Lighting equipment: a primer

One of the overwhelmingly popular requests I seem to get is for an article on lighting – specifically, how I achieve what I achieve with my images. This article will be the first in a series of five, covering various aspects of lighting and deconstructing the source. It’ll also serve as a useful prelude to my studio lighting workshop tomorrow.

Before we do that, it’s important to establish a baseline: if you don’t know what it is you’re using, then it’s going to be both time consuming to explain, and difficult to understand. Thus, we’re going to begin with an explanation – a quick 101, really – of common lighting sources, tools and modifiers – and an explanation of what they’re useful for, and how one would deploy them. Please excuse the crude line drawings; I don’t have a lot of these objects myself, hence a lack of source images. We’ll go down the list in alphabetical order.

barndoor

Barn doors
Moving plates fixed to a light to control spill off. Useful for creating strongly directional light and preventing too much from reaching the background behind the subject.

beautydish

Beauty dish
A set of nestled reflectors fitted to the end of a studio strobe to create a ringlight effect for portraits/ faces – soft, without shadows, but still with some definition.

diffuser dome

Diffuser dome
A clip on bit of translucent plastic that goes over the end of a flash to soften its output. Usually makes almost no difference but eats a lot of power.

diffuserpanel

Diffuser panel
Any sheet of semi-translucent material that goes in front of a light source to soften the directionality of its output; varies in thickness and opacity.

flash

Flash/ Speedlight
Small, portable, self-powered light source. Usually mounted to the camera, and communicates with the camera’s meter using electronic contacts to control output power. More sophisticated models are capable of wireless operations, triggered optically by another flash and with metering taken care of by the camera. The flash head itself has some modifiers built in – usually zoom, which controls beam spread, in addition to being aimable.

gel

Gel
A piece of transparent, colored plastic that filters the output of any light to balance it with ambient sources; usually yellow/orange or green to balance tungsten and fluorescent sources respectively.

gobo

Gobo
An opaque piece of material with a cutout to permit light to pass through; usually with a shape or design. Used more frequently for productions than photography. The best example of a gobo is perhaps the Batman sign…

grid

Grid
Exactly what it sounds like – a grid of panels placed at right angles to the light source. Acts like an array of 90 degree barn doors; controls light spillage and ensures that most of the light goes in one direction, but without the hard edges that barn doors produce.

HMI light
Very bright incandescent source in the form of a studio strobe – used for video production. Compatible with all normal accessories, e.g. softboxes/ gobos/ diffusers etc.

_5001017bw copy

LED Panel
Continuous, low-temperature light source. Nowhere near as bright as HMI lights, but also nowhere near as hot. Useful on location when you have to operate off batteries, or when you have to photograph temperature-sensative objects – ice cream, for example.

monoblock

Monoblock
Any self-contained studio light that doesn’t require a separate power source or transformer. Plugs directly into the wall.

radiotrigger

Radio triggers
Wireless trigger for flashes or strobes that isn’t restricted by line of sight. Requires one controller on-camera, and one for each flash unit.

reflector

Reflector
A piece of material – usually white/ silver or gold (warm) – held below a or to one side of a subject to provide fill light on the shadow side by reflecting the primary light source. Softens out the shadows. Usually requires an assistant, as in, ‘Tilt the reflector down a bit more, thanks.’

ringflash

Ringlight/ Ringflash
A flash with a circular tube, or a light shaper in the form of a ring that simulates the effect of a circular tube. Once again, useful for portraits.

softbox

Softbox
A tent of sorts – usually fabric – which the light source fires into at one end, with a semi-translucent window at the other end. The insides are usually reflective to minimize light loss. Creates a large, soft, diffuse light source; comes in many sizes. Useful for anything and everything. Can be used in conjunction with grids, barn doors, etc.

snoot

Snoot
A cone-shaped object, open at both ends that goes over the end of a light source to create a very tight, intense beam of light – effectively a spotlight.

stand

Stand
Anything used to hold your lights or accessories.

Strobe
Large studio flashes – much more powerful than portable flashes/ speedlights, but require mains power or large lead-acid battery packs to run.

umbrella

Umbrella
Umbrellas come in two varieties: shoot through and reflective. The former act as diffusers; the latter produce a slightly harsher, more directional (but still diffuse) light. Usually deployed in conjunction with flashes or smaller studio strobes. More light loss than a softbox because the sides are open; not always a bad thing because sometimes a little ambient illumination is required.

zoom head

Zoom head
The part of a flash that allows control of the beam spread – it’s called a zoom head because it allows the photographer to match the angle of coverage with the field of view of the lens, with minimal power wastage.

Stay tuned for subsequent parts – we’ll cover reverse engineering setups, and some more advanced techniques and tricks. MT

10×10: 100 ways to improve your photography

This article was originally posted in a series of 10 mini-exerpts back in the very early days of the site; Google Analytics tells me that it was hardly viewed, which is probably a shame – so I’ve re-packaged, updated and re-presented it again here as a monster all-in-one reference. Enjoy. MT

Disclaimer: I’m assuming you already know the basics.

Part one: Compact cameras

Pretty much everybody has a compact, even if it’s only the one built into your phone. It’s no good for serious photography. Or is it? You might find yourself using it more if you try some of these ideas…

10: Carry spare batteries. One in the camera, one in your pocket or one charging. This lets you keep going – especially important since compact battery life is often terrible.

9: Use the hand strap. It seems obvious, doesn’t it? But you’d be surprised how many people don’t, and then land up having to buy new cameras.

IMG_1330b copy

8: Shoot bursts, if you have a useable buffer. Without the buffer, you’ll just have to rely on timing and counting shots – think of it as a revolver rather than a machine gun. The same rules about the middle shot being stable and sharp in a burst also apply to compacts.

_0011033bw copy

Zoom. Ricoh GRDIII

7: Keep ISO as low as possible, and make use of the stabilizer. Most good compacts have stabilizers; this is because even with the 1/focal length rule, there’ll be enough camera shake to blur things – you’re holding a light object at arms’ length and trying to keep it still. Granted, there’s no mirror slap, but there’s also nothing to brace against, either. Keeping the ISO as low as possible lets you maximize image quality. There’s usually a big difference between even base ISO and one stop up; know the limits of usability and don’t exceed them.

6: Look at the whole frame. I’m not sure how to say this more succinctly: there are things compacts can do that larger sensor cameras can’t – think of telephoto/ compressed perspective shots where everything is in focus, for example – and vice versa (shallow depth of field, wide FoV). Look at the whole scene, and see how you can use these strengths to your advantage. Images shot with compacts that work actually force you to have a much stronger composition, because you cannot rely on the crutch of bokeh or let the lens do the talking.

_0011492 copy

5: Spot meter. Dynamic range on all compacts is limited because the pixels are small. This means losing the shadows or the highlights is inevitable under most situations; you need to decide which one is important. The spot meter (and a half press to lock exposure) helps you to do that. High key = keep the shadows and lose the highlights; low key = keep the highlights and lose the shadows; most important however is making sure the subject is properly exposed – use the spot meter over faces, for instance. The other alternative is to use the spot meter on highlights and add a stop of exposure compensation – the meter will try to average a middle gray exposure out of whatever you place the box over; you know the camera has a little more tonal range in it if the highlights are at middle gray, so you can safely add some positive exposure compensation. This generally makes the rest of the image a little dark – especially under harsh light – but it also has the side benefit of making the colors richer.

4: Use P mode. I’d say leave it in full auto, except most of the time that doesn’t let you control exposure compensation and metering – those are important. Why not use aperture priority, as I’d recommend with a larger sensor camera? Simple: there’s no point. The real focal length is so wide and the lenses usually so slow that DoF is enormous, and changing the aperture isn’t going to do anything other than reduce the amount of light reaching the sensor. Great if it’s bright, but if you stop down too much, you’re going to to induce diffraction and just land up with soft images.

3: Keep the lens clean. I’m constantly surprised by how many people have dirty lenses on their cameras and then complain that the images aren’t sharp, or that they can’t see anything in the finder – but there’s fingerprints all over it. It’s especially important on a compact as the small sensor and high pixel density are very demanding of lenses; the more aberrations you have on yours, the lower resolving power is going to be.

2: Prefocus. Although focusing speeds have improved dramatically, what’s really nice about most point and shoots is the half press to full press lag is actually quite low – but you need to be prefocused first. In any case, the huge DoF will cover any minor focus errors. Most fleeing moments can be captured with a compact and a little anticipation.

_0011588 copy

1: Set up your camera to either shoot raw, or output as neutral a jpeg as possible. If you can’t get a raw file, there’s still a lot that can be done with a good jpeg – what I usually do is reduce contrast to minimum to preserve the highlights and shadows; turn saturation down, and lower (but not zero) sharpening. Reason being that if you zero sharpening, you do generally lose some detail on compacts as this step is applied to the raw data in the imaging engine before being saved as a jpeg. You’ll be surprised how much you can do with one of these files afterwards in photoshop. Similarly, avoid those fake HDR or extended dynamic range modes; they might appear to help but what they actually do is make highlights look very unnatural because the tonal values overlap with other parts of the luminance range.

Part two: DSLRs

Disclaimer: I’m assuming you know the basics already, but want to get serious.

10: Control your view. Use the viewfinder when you can; there’s less lag, you can brace the camera against your face to increase stability, the dynamic range and resolution are higher, it’s a more direct connection to your subject and it saves power to boot. But why not use live view if you’ve got it, especially coupled with a swiveling screen? For critical focus, odd angles, and video, it’s actually pretty handy. Though I personally avoid it like the plague unless i have no choice.

9: Shutter button technique matters. You’d be surprised how many people just jab the button and wonder why the camera isn’t responding. Firstly, don’t jab. Roll your finger gently to reduce camera shake. Secondly, prefocus; the shutter button has two stages – the first activating autofocus, the second, shutter release. If you have focus already going, then your lag is going to be much, much shorter than if the camera has to do all the work when you press the button – even on the fastest cameras. Finally, you’d be surprised how many people use the horizontal release in portrait orientation even if they have a vertical one – don’t. It’s less stable, and frankly you just look silly.

Night party. It looks bright, but the EXIF will tell you otherwise. I needed every single trick in the book to get this shot: stratospheric ISOs, low shutter speeds, and a fast f1.4 lens wide open. Nikon D700, 24/1.4.

8: Turn the in-camera sharpening and contrast up to maximum. What? Why? There’ll be haloes! I can hear the cries of incomprehension and derision already. First caveat: you must shoot raw. Second caveat: use a raw processor that ignores the camera’s proprietary processing tags, e.g. Adobe Camera Raw. The reason why you want to crank both of these things up is that the camera’s preview engine generates a jpeg based on these settings; if your exposure is okay with the contrast at maximum, then you know you’ll have more shadow and highlight latitude. And high sharpening accentuates the differences between in focus and out of focus.And it also accentuates noise; basically, the combination of these settings makes it easier for you to tell if you’ve nailed it or not.

7: Don’t let zoom lenses make you lazy. Select a focal length based on perspective, not angle of view: in other words, don’t use a wide lens because you want to get more of the scenery in, or a telephoto because you want to get closer. Instead, wide is for accentuating perspective, telephoto is for compressing it.

Action. An interpretation of the famous first series of motor drive images that showed a galloping horse’s legs do in fact leave the ground simultaneously. Nikon D700, 28-300VR

6: Shoot in bursts. Events evolve. The first shot may not be the best, or you or your subject may move. A burst is insurance, and if they’re all perfectly focused and exposed, then it lets you select the best image – say for minor variations in facial expression of a portrait. Note that I don’t mean machine gunning the shutter until your buffer is full; three or four shots is usually plenty.

Fire. The balloon was firing on and off unpredictably. It would be a lot more difficult to get this shot without auto ISO. Nikon D3100, 85/1.4 G

5: Use auto-ISO, but only if it’s configurable. If the minimum shutter speed is not configurable, you don’t know at what shutter speed the camera is going to start bumping the sensitivity; if it’s too early, your images will be grainer than they need to be. If it’s too late, then you may not have enough shutter speed for a sharp shot.

Cheers. Tough lighting; how do you know what your camera is going to expose for if you haven’t tried it out? Nikon D700, 85/1.4 G

4: Know what your camera is doing: AF, metering, auto-ISO. This is actually very, very important. If you don’t know how your camera responds under a given situation, how do you know if you can get the image or not? There’s no shortcut to this other than a lot of practice and experimentation.

Alien. I prefocused on the spot where the man would be when the light was exactly behind and over him, then waited. Nikon D3, 24-70/2.8 G

3: Have some way to control your AF: either use AF-ON or AF-L, together with continuous focusing. Autofocus is an aid, not a crutch. Auto-select point systems will seldom select the point you want; they’re useful, but only in an environment where you have a lot of randomly moving subjects and need to pick the closest one. When you have something a bit more sedate, tell the camera what to focus on. Use continuous autofocus, because everything moves, if only slightly; the larger your aperture, the more this will matter because depth of field is shallower and probably won’t be sufficient to cover subject movement. I prefer to have AF activation on the shutter button and an AF-Lock button configured under my right thumb – this is so I know I can just press one button and have a high chance of getting the shot – but I also know of plenty (most sports shooters?) who configure AF-ON under the thumb, and the shutter button to capture the image only. AF Lock for that configuration is of course done by releasing the AF-ON button. Try both and see which works for you.

This was actually shot in a well lit carpark, but with a stopped down lens and fast shutter speed to eliminate ambient and have nearly 100% of the exposure provided by the flash. If I’d shot aperture priority, I’d still be able to see the surroundings. Nikon D700, 28-300VR and three SB900s.

2: Shoot aperture priority, except for flash. This is the easiest way to maximize control of your camera: aperture priority to control depth of field, manual mode if you need to balance flash and ambient lighting.

Watching the world pass by. Imagine this frame without the edge intrusions: it’d feel pretty different, wouldn’t it? Nikon D700, 85/1.4 G

1: Watch the edges of your frame. I’ll say it time and again: what usually makes or breaks a photo, or the difference between an excellent image and an outstanding one, is how well the subject stands out. This is both a function of subject lighting, positioning and focus, as well as the inverse: what other things are there in the frame that take attention away from the subject? Intrusions into edges are one of the main ones. Conversely, there are also compositions where edge intrusions are welcome, or even make the image: they suggest things that might not be there, or leave things to the imagination of the reader. Use with care!

Part three: Mirrorless cameras

Mirrorless: the middle child? Maybe. But even a diehard sceptic like me has discovered that these things have their uses –just be clear about your expectations.

10: Spare batteries are an absolute must. Due to the large sensor, LCD and high demands from lens focusing motors, stabilizers and the like, mirrorless cameras have the highest power draw of any type of camera (other than medium format digital, it seems). Make sure you have at least two to get you through a day, maybe with an additional spare.

9: When selecting a camera, look at two things: useability (including lens choices) and raw sensor quality. I’ve tried the Panasonics, Sonys, Fuji and Olympus systems; of all of these, only the Olympus E-PM1 Pen Mini stayed more than a month. Why? Because it’s the most responsive and configurable of them all. The Panasonics are very configurable but not very user friendly. The Fuji X100 has the best image quality, but the firmware is a disaster and it’s slow as molasses. The Sony is reasonably responsive, but not so easily configurable and the lens choices are pretty limited. And the NEX-5 I owned had a strange color palette. And don’t pick one so big that you might as well take your DSLR.

8: Use a hand strap instead of a neck strap. If it’s in your hand, you’ll be ready faster. And more likely to use it. And the weight/ size aren’t so bad you need to hang it around your neck or shoulder for relief. It also takes up less space in your bag when you have to store it.

7: Adaptors are useless. Although they seem like a good idea, mirrorless systems are optimized for telecentric lenses with very short back flange distances; conventional SLR or RF lenses aren’t designed like this and thus don’t work well on mirrorless cameras. It’s quite well known that RF wides have numerous issues like cyan/magenta shifted corners, increased CA and vignetting. Adapted lenses are also bulky and lacking in automation – no AF, no aperture control, no stabilizer. And accurately manually focusing something held at arms’ length is near impossible.

_PM03612 copy

6: Remember the lag. Even though release lag may be in the 30-40ms range, you’re going to have another lag induced by the LCD itself – the best models refresh at 60hz, which means you’re looking at least another 15-20ms (or more) of additional lag as the screen refreshes to show the current scene. Practice to get a feel for the rhythm of the camera.

5: Avoid continuous AF. Contrast detect AF systems still aren’t good enough to track moving subjects – with the exception of the hybrid system in the Nikon V1 that also has phase detect photosites built into the sensor – so either prefocus and anticipate, or cover with DOF.

4: Carry it everywhere. No point sacrificing image quality if you’re going to leave it at home like the full size camera. This is also why I’m drawn to the smaller, more pocketable mirrorless cameras like the Olympus Pen Mini. I’ve put it on a hand strap and use a pancake lens most of the time; it’s not a lot bigger than a compact but produces vastly better image quality.

3: Use the EVF if you’ve got one. Like any optical finder, bracing the camera against your face helps stability immensely. I’m not recommending going out and buying an add-on finder; these are usually flimsy, unwieldy and dramatically increase the size of the camera – defeating the point of mirrorless in the first place.

2: 1/focal length rule doesn’t apply anymore. Why not, aside from crop factor? Because most of the time you’ll be using live view and holding the camera at arms’ length – this means increased propensity towards camera shake. Double, or even triple that for critical shots or action. Or use a flash. And while stabilizers help, they probably bring the safe speed into the 1/fl rule or maybe very slightly better.

1: Compose like an SLR, shoot like a compact. They’re hybrids, right? Treat them as such. You get the DOF of an SLR – which means you have to watch your focus point, and take care in choosing perspectives. But you also have the limitations of a compact – so remember to watch your exposure/ highlights/ shadows; prefocus; don’t expect it to be able to track moving objects. Remember the limitations of both, and that should give you a good idea of how to get the most out of your mirrorless camera.

Part four: Rangefinders

10: Timing, timing, timing: shoot lots and get to know the lag rhythm of your camera. It might feel instant, but it isn’t. That split second can make or break the difference in a critical shot, especially during a fast-paced situation – that fleeting expression, or arrangement of people.

9: Get to know your lenses: There is no such thing as the perfect lens. All of them have idiosyncrasies, be it focus breathing, focus shift, curved focus planes, flare under certain conditions, or maybe the ability to produce brilliant 14-pointed stars from point light sources at f16. (Don’t laugh, the Leica 21 Summilux ASPH does this.) The better you know your lenses and the way they draw, the more you can exploit their properties to help your pictorial rendition of a given situation. It’s also why I’ve got eight ways to get to 28mm – there’s a huge difference between the Zeiss ZF.2 2/28 ‘Hollywood’ Distagon and the Ricoh GR-Digital III, for instance.

8: Use a soft release and thumb grip (and maybe front grip). Anything that can make your grip more secure or comfortable, and your shutter release action more gentle, is your friend. I like the Thumbs Up, personally.

7: Don’t limit your subjects to the center focus point. You can focus and then recompose. But remember that most lenses aren’t flat field (especially rangefinder designs, which are usually non-retrofocus and spherical) so a little tweak to the focus ring is required for edge subjects – usually to make the focus point slightly closer, as the focal plane will be curved slightly around you. Experience is required to determine exactly how much and when to shift – this is why I also highly recommend using fewer lenses but knowing them well.

6: Use the DoF scales to prefocus. Especially useful with wide lenses, whose large DoF means that you might even be able to shoot hyper focal and not have to focus at all: especially great for being fast and reducing time between seeing the shot and capturing it. Very important skill for street photography and photojournalism. You can practice this by estimating distances and setting your lens with the camera at waist level, then checking in the finder.

5: Pay attention to the edges. The frame lines are a suggestion: there will be more included. With experience, you can push the composition a bit and still get everything in.

4: Shoot with both eyes open. The nice, bright, high-magnification finders are great for letting you a) see what’s outside your frame and might make composition better or worse if included or excluded; and b) you can keep both eyes open to enhance your peripheral vision. It’ll also stop you from getting run over.

3: Know the limitations of the system. By their nature, your finder will probably only cover 28-135, and not be very accurate for 90 and 135. So really, the strengths of the system lie in the 28-75mm range; don’t try and do birding with one of these things and wonder why your results aren’t up to par. (Note: I do use my M9-P for macro work, but that’s a different story entirely.)

2: Less is more. Rangefinders are small and light: why burden yourself and turn photography into endurance sherpa-ing? Try reducing your regular kit to two, or better yet, one lens. Either something which provides to distinctly different perspectives, or perhaps something in-between. I choose 28/50, after a long time trying to make the single 35 work for me. It just didn’t agree with the way my eyes worked, which is a shame because the 35/1.4 ASPH FLE I had was easily one of the best lenses I’d ever used, period.

_M9P1_L1007298 copy
As above, so below. Leica M9-P, 28/2.8 ASPH

1: Check your rangefinder calibration. There’s nothing worse than shooting an entire series at f1.4 and thinking you nailed focus – or at least remembered doing so in the finder while shooting – then being horrified as you open up the set only to find your subjects’ noses in focus and their eyes a distant plane away. If you know how to calibrate your rangefinder, great; if not, it might be the subject of a future post here (but I take no responsibility if you damage something or void your warranty). If you don’t dare, send it in to your dealer. The best thing you can do is have your body calibrated to match all of your lenses – so send them all in at the same time. The next best thing is to have it calibrated for the lens with the shallowest DoF; the one exception is if the lens suffers from focus shift. Then you’ve got no choice but to calibrate for your most frequently used lens and remember which direction to adjust for later. Check calibration often and if you get a new, shallower DoF lens. One last related point: make sure all of your viewfinder windows (VF, RF patch, frame lines, front VF) are clean – you’ll be surprised how much easier it is to focus!

Bonus for Leica M8/9 users: The meter is center weighted and very heavily biased towards protecting highlights. So, for backlit subjects there are a few ways of compensating. a) Lock exposure with the camera aimed at something of roughly equal luminance but not backlit; this works on the shutter half-press position (with a little dot displayed at the top between the leftmost digits in the finder) if you’ve got the release mode set to standard. b) For M9 users, use the rear dial to activate exposure compensation. I personally don’t like this, because I have no idea if I have it set or not, and if so, how much. c) If you’re shooting with fixed and not auto-ISO, then note the shutter reading in the finder, and move the shutter dial to something appropriate. I use a slightly more complicated method, with auto-ISO: if the shutter speed displayed is over the minimum you set, then you know the camera is in base ISO. I just manually set it to something lower; the camera can’t lower the ISO any more, so it overexposes as desired. If the situation is dark and you’re above base ISO, this doesn’t work. In very dark situations, I usually just leave the camera at ISO 1250 and go manual with the exposure.

Part five: Photojournalism and street

Photojournalism (hereafter PJ) and street photography go hand in hand: they’re about capturing a moment of life. PJ goes a bit further by adding a story to that moment; street can just be an aesthetically pleasing moment in and of itself. Both though require the photographer to be observant and ready. This is what works for me.

_M9P1_L1004918bw copy

10: Watch your shutter speeds. You’re going to need more than 1/focal length – maybe 1/2x to be safe, or even 1/3x if you’re running and gunning. You’re moving, your subject is moving, and nothing is steady. Remember also that the higher the resolution your camera, the less forgiving it is of focus errors and camera shake.

9: Small, nondescript cameras are best. They don’t draw attention to you – especially in the current day and age of everybody carrying a camera, nobody is going to take you seriously if you have a small black compact. You’d be surprised how much I get away with using the iPhone or Ricoh GR-Digital III. People simply don’t perceive it as threatening in the same way a pro DSLR and 70-200 might be. Compacts also give you more depth of field for a given aperture.

8: Shoot wide and close. The perspective produces a stronger image; wide lenses are also more forgiving to focus errors and camera shake. And as a bonus, you get context in the frame as par for the course.

7: Anticipate and observe. To quote the Cartier-Bresson: pick the decisive moment. To do so, you need to be aware of everything around you; really look. Pay attention to the details. People are fairly predictable; it should be easy to spot if something out of the ordinary is about to happen. Anticipation of the action gives you a vital few seconds more to prepare and be in position, or have the camera out.

6: Blend in. Act like you belong, dress nondescript, and nobody will pay you a second glance. It will make your job a lot easier. If you draw attention to yourself – be it by being uncertain or provocative – then people of course notice.

5: Always have the camera to hand. How are you going to get a quick shot off if the camera is in your bag? You should be able to get a shot in less than 5 seconds – sometimes your window is even shorter than that.

4: In a real emergency, help. Yes, our duty as a PJ is to record, document, communicate and raise awareness about the events around you; you help by telling a story. But you don’t have to shoot all the time. Get your shot and then help out the people. Remember that at the end of the day, we’re all human.

3: Practice, practice, practice. Use your camera until you’re fast and proficient; you should be able to visualize the frame and field of view without having to raise the camera to your eye. You should be able to set things by muscle memory and have a group of settings (if your camera supports this) that configures the camera to be ready to go.

2: If spotted, acknowledge your subject. A friendly smile, a sincere nod – all of these things make people feel comfortable with your presence and make your life easy. You don’t have to stop and talk or explain what you’re doing if nobody is asking. Smile and move on. Done.

1: Be confident. It is better to say sorry rather than ask permission and miss the shot. With that, go out and be productive.

Part six: Lighting

This post deals with the light you create. You can’t always find what you need, so it’s important to know the dos and don’ts of off camera lighting. My tips apply to speedlight users; I’ve never been a huge fan of monoblocks, nor have I used them very much since Nikon launched their CLS system. Sure, sometimes you wish for more power, but then again you remember that you can go for hundreds, if not nearly thousands, of shots on a set or two of AAs – instead of carrying a 50kg lead acid lump around. Read on.

10: Always shoot in manual mode with flash. Otherwise, there’s no way you can balance your flash and ambient exposure; if you want all flash, then you can dial in the highest sync speed possible – this will help you avoid camera shake. If you let the camera decide, it will usually only get it right for the center portion of the frame when the flash exposure is much greater than the ambient exposure. This is to say, most camera systems are useless at daylight fill, especially under very bright conditions.

9: Imperfect diffusers and softboxes add character to portraits, but not product shots. Uneven lighting for most product shots just makes the object look odd. For people, it can be strangely flattering. Consider making some shoddy homemade internal baffles for your portrait soft boxes.

_M220416bw copy.jpg

8: If you’re controlling lighting, you shouldn’t have blown highlights or blocked up shadows – unless you want them. Self-explanatory. Your lighting isn’t balanced properly. Try again.

_3007528bw copy
Intentional outline. Nikon D3, 105VR, one SB900 off camera.

7: Those clip on diffusers are pointless. A small light source can never replicate a big light source unless you expand (and diffuse) it – be it bouncing off the ceiling, or a softbox. A little clip on diffuser is just going to make a small, diffuse source – which at any distance, looks like a small intense source except weaker. You’ll get the same reflections and general lighting feel. All you’ll have done is a) look stupid b) wasted your money and c) lost at least two stops of light. I’ve never even used the diffuser domes supplied with any of my flashes; they’re still in the plastic bags they came in.

6: Duct tape is your friend. Use it to tape flashes in odd positions to whatever supports might be handy; sometimes you just can’t erect a flash stand in the place you want it. But you could tape the flash to the ceiling. I’ve done it before.

_3009669bw copy

5: More flashes are better. I’ve got four; two primary units, one spare, and one more unit to use as a commander on cameras without a built in (Leica M9-P, I’m looking at you). Legend has it that Joe McNally travels with an entire suitcase of SB800s. I dread to think how many batteries he goes through every year.

_7047913 copy
Alfabeti. Nikon D700, 60/2.8 G 2xSB900s

4: If you’re short of lights, consider a reflector. Positioning one light directly opposite the reflector gives you another pseudo-light – depending on the reflector, it could be as little as 1 stop light loss – think of a mirror, for instance. A more diffuse reflector can provide gentle fill.

_X1_L1001004bw copy
Leaf shutter benefits. Leica X1, SB900, 1/2000s.

3: Higher sync speeds are better. Pro DSLRs top out at 1/250s for full power, or less power and faster – but these are not true ‘flash speeds’, because the flash has to fire for longer but at reduced power – note how the flash no longer freezes motion at 1/8000s as much as it did at 1/250s. Leaf shutter compacts like the Ricoh GRDIII and Leica X1 both sync to 1/2000s; they’re great for capturing motion or providing balanced daylight fill, where your ambient shutter speed might be very high. You won’t lose the highlights, and you also won’t lose the shadows – thanks to your high sync speed.

2: Remember the eyes. For living subjects, a little catch light reflected in the eye can make all the difference between a flat, boring shot and a portrait that looks alive. Use a reflector, or if you’re using Nikon CLS, the trigger flash on your camera works fine too.

_X1_L1000981bw copy
Note the eyes. Leica X1, SB900.

1: Spare batteries are important. Never get caught short. I avoid NiMH as they tend to exhibit the memory effect, especially if not used frequently – as would be typical for your second or third spare set. The Sanyo Eneloop batteries are fantastic – they really do hold charge like alkalines, but have the reuseability and current draw properties of NiMH. I’ve got eight sets of these for my flashes, and only charge them when depleted.

_7040287 copy
Macro lighting is quite a different game entirely. There isn’t a lot of working distance, and you need a lot of diffusion to create the same apparent perceived light source size.

Part seven: Postproduction and editing

Photoshop is a fix all for everything, right? It’s also come to represent a dirty word; when something has been ‘Photoshopped’ it’s no longer authentic or original, and the skill of the photographer has been severely diminished. Wrong, think again. Photoshop is the equivalent of the darkroom from the film days: sure, you can add things to the scene, but they look odd and unnatural. The main thing you did in the darkroom was finalize the exposure: adjust the density and brightness, and fiddle with the contrast. Maybe some dodge and burn. How? Chemical mixes, timing and cutout masks. We do the same now – except the chemicals are your raw converter and curves layer, the fixer is your save button, and dodge and burn is a brush tool.

So what is editing exactly? The process of removing unwanted material – in this case photographs – to leave a more coherent story or narrative; being selective about what you show is just as important as having something to show in the first place. There’s no point in having technically brilliant but boring images – but you can make a story out of perfectly timed moments, even if they’re a little noisy or blurred.

10: Keep all of your raw files. You never know when somebody might ask for a color version of a B&W image; don’t lose that sale because you were trying to be cheap on storage. Storage IS cheap.

_M9P1_L1005824bw copy

9: Sharpening should be the last step. If you sharpen too early on, you’re to end up with extra noise and less tonal information, especially for images with a lot of fine detail. Why? Because of the way sharpening works. It increases apparent acuity between adjacent areas of different luminance by increasing the difference in luminosity between them. Making something brighter or darker – with images containing a lot of fine detail, this means a change to a large area of the image – will inevitably destroy some tonal information, especially at the extreme ends of the tonal range.

_7046623b copy

8: Let your images mature before deleting. Look at your images immediately after a shoot and pick out your favorites. Then do this exercise again two weeks later. You’ll probably find that there’s been a big change. Why? Immediately after the shoot, you remember how difficult it was to get one shot; that effort put in affects your artistic judgment. Two weeks later, you’ll probably not remember as clearly, and you’re more likely to go with your first instincts. Go with the latter selection.

A tale of two frames. I initially preferred the first frame; but a month later, I think there’s more of a story and more contrasts in the second one. M9-P, 28/2.8 ASPH

7: Calibrate your monitor. Whether you use one of the Spyders or the built in utility in OS X, it’s important to adjust your monitor to produce as accurate color as possible – this is important for both print and screen; you want to make sure that other people see the same thing you put in so much effort to create. For print, you can attach the color profile to the file; a good printer will be able to match the print to what you see on screen. It’s also important to know the gamut of your monitor; I’ll never do any serious editing on my 11” MacBook Air because the screen has terrible color. On the other hand, the 27” iMac/ Cinema Displays are fantastic, as are the 15” and 17” MacBook Pros.

_M8_L1023901 copy
Intentional color. Leica M8, 21/1.4 ASPH

6: Do most of your adjustments in the raw converter. This is important, because the data is in its highest bitrate form – which means making large changes to the file at this stage has the least impact on image quality. If you do highlight recovery on a 16 bit raw file, you’ll probably have a decent stop or two (assuming a good sensor) before you get posterization or false color. Now try doing the same to a jpeg and you’ll see what I mean. By the same token, keep your files in the highest bitrate form until you’re absolutely sure you’re not going to change anything again – and that might be a Photoshop file in 16 bit with all layers, or it might be a quality 12 jpeg. I generally don’t edit again, so I save my finished files as a maximum quality jpeg. Remember that print doesn’t have as much dynamic range as a computer screen, so if it looks fine on a calibrated monitor, it’ll probably look fine in print.

5: Buy a good tablet. I like the Wacom Intuos 4. It will help you immensely to lay precise masks and control your dodge and burn; the tip is pressure and tilt sensitive to control brush size and density. It’s much faster than doing things with the mouse, too – once you get used to how the entire tablet area maps to your screen. Get one that suits your screen size. The medium 6×9” is perfect for my 15” MacBook Pro.

The Beach. Leica M8, 50/1.4 ASPH

4: Don’t overdo anything. Turning it up to 11 works for some shots, but not most. Too much sharpening leaves haloes. Too much contrast loses tonal detail. Too much saturation makes it feel unnatural and cartoonish. Etc. And don’t even get me started on overuse of HDR; overlapping tonal values are jarring to the eyes.

_D90_DSC2987 copy

3: Always have backups of your backups. I’ve had a situation where a new OS caused some serious issues with my primary computer; the upshot was that none of the files were readable. My primary backup drive – a Maxtor; I’ll never buy one of those again, just too many have failed – started making the click of death when I connected it, and I was able to get most of my data off in time before the drive crashed and died. Good thing there was one more backup copy. My current management strategy is to keep all finished jpegs on my editing computer; there are two duplicate backups with all the raw files (in the same file structure) on external drives, one of which lives in my bag and goes with me everywhere; I also time machine the primary drive whenever I do a backup to the externals. Generally I’ll do a backup once I finish editing a batch, which might be 50 or 100 images or thereabouts. Storage is cheap. Lost files are priceless.

2: Integrity matters, especially for photojournalists. Whilst I’ll have no compulsion removing dust from a watch product shot or litter from fine art street photography, I absolutely will NOT touch the content of the image for photojournalism. This is because once you do, and if you get caught, your credibility is instantly nonexistent.

1: You can’t polish a turd. Don’t think that you can rescue a compositionally weak image ‘in Photoshop’. You can’t. You can’t change the lighting. If you didn’t get it mostly right in-camera, you’re not going to be able to fix it in Photoshop. You can fix exposure, color, contrast and the way the image appears; you can’t change the content. If an image is good, however, you can make it extraordinary.

Part Eight: General tips for all photographers

Here are some suggestions that apply to everybody, regardless of what or how you shoot.

_M9P1_L1007399 copy
Prague. Leica M9-P, 28/2.8 ASPH

10: Shoot raw and expose a little bit hot. There’s always a bit of potential to recover highlights in your raw files; some cameras more than others. Know how much yours can tolerate before blowing highlights completely. It’s not just a way to expand dynamic range; exposing hot and bringing down the exposure later actually reduces shadow noise, too. For those of you using a third party RAW converter that doesn’t read proprietary image settings, crank your sharpening in camera up to maximum – it won’t affect the raw file (only the jpeg preview), but you will be able to more easily see if things are in focus or not when using the image review screen.

_M8_L1017249 copy
But we all have favorites. Billingham Hadley Pro. Leica M8, 50/1.4 ASPH

9: There is no perfect bag. Just accept it, and move on. Buy a new one if it takes your fancy but don’t expect it to solve all of your problems. Most of the time I only use a bag if I have other non-photographic items to transport. If it’s camera-only then it just goes over my shoulder.

_M9P1_L1004990bw copy

8: Watch the edges of your frame. Your subject is identified by a) light; b) position in the composition; c) context. The edges add or remove context – and with it, distractions. Use them carefully.

_PM03439 copy
Spotlight. I’d have missed this if I was fiddling with my settings. Olympus E-PM1, Panasonic 20/1.7

7: Learn your equipment. You should be able to operate your cameras like it’s second nature. Muscle memory is your friend, and can make the difference between responding instinctively and getting the shot, or missing it altogether. Practice is the only way to do this.

_PM03858 copy
The ephemeral sushi. Nothing is in focus, the saturation is all over the place, there are hot spots, the color isn’t accurate…but somehow, it works. Olympus E-PM1, Panasonic 20/1.7

6: Look at lots of images. Famous works. Not so famous works. Flickr. It’s a good source of both inspiration and way of helping you to hone your sense of composition.

_D90_DSC0431bw copy
But surely it will make me a better photographer!

5: Don’t buy new gear unless you’re sure you’re not the limitation. Make sure you know exactly what it is that your current gear isn’t doing for you and how the new gear will solve it.

Homage a Rene Magritte. Prague. Olympus E-PM1, 45/1.8

4: Look at other mediums of art for inspiration. It could be painting, design, architecture; for instance I love the way Magritte renders clouds, and I look for that kind of light when shooting skies.

_M9P1_L1005830bw copy
Gorilla in the shadows, Prague. Leica M9-P, 28/2.8 ASPH

3: Look for interesting light, not just interesting subjects. But of course it’s best to have both. The best photos present an unusual subject in an extraordinary way.

_7036002 copy
Precision. I waited for both the sun and the bird. Nikon D700, 24/1.4

2: Be very, very selective with your keepers. Keep only the best. I throw away 99% of what I shoot. Not because it’s bad, but because if you shoot good pictures, then keeping only excellent will make you excellent after a while; if you shoot excellent on average and keep only outstanding, then you’ll be outstanding. And so on. Continually push and challenge yourself – set assignments, practice, tasks. Go outside of your comfort zone, and the persistence will yield results.

_0012621 copy
Serendipity. Interesting things happen when you stick a compact inside a marine chronometer then do wide-angle macrophotography with it; this was my first time trying it. Ricoh GR-Digital III

1: Shoot lots. Practice, practice, practice. Experiment. If it doesn’t work, at least you’ve learned not to do it. If it does, great – another technique to add to the arsenal. I always get asked ‘how do I pick it up? How did you pick it up?’ and my answer is the same: I experimented and shot a lot. But I also made sure I made a note of what I did, so I learned something from the experience. When I started, I was probably doing a thousand frames a day – 99.9% were crap, of course – but slowly that ratio swung. Always carry a camera – even if it’s just your phone – and don’t be afraid to use it.

Part nine: Birding and wildlife

The focus of this post is on birding and wildlife: it’s something that every aspiring serious amateur photographer will probably try at least once, usually right after they purchase an enormous telephoto lens. Bragging rights are only good if you have the images to go along with the lens.

_3022426 copy

Cattle egret. Nikon D3, 400/2.8 VRII

10: Dress right, bring mosquito/ insect repellant, and carry a bottle of water and a hat. The environment where some animals live can be harsh and remote. You’re not going to be concentrating on the photography if you’re not comfortable.

_3020442 copy

Scarlet ibises. Nikon D3, 70-300VR

9: Pay attention to the time of day. There’s no wrong or right time to shoot, but there is good light and bad light. Bad light is flat and uninteresting, and doesn’t flatter your subject. Good light is always tangential and thus creates contrasts; better still, it can isolate your subject from the background. And if there’s plenty of it, that’s a bonus because you can use a higher shutter speed.

_D3T1396 copy.jpg

Eagle. Nikon D3, 300/2.8 VR + 1.4x

8: A sharp but noisy image is better than a noise-free but blur one. Unless your intention is to be artistic or atmospheric, it’s better to have grain than none but also no idea what the subject actually is. This goes for all subjects, and types of photography: if your subject and composition are strong enough, nobody is going to care that the shot is grainy – look at Robert Capa’s Normandy Beach landing photos.

_D3T1215 copy.jpg

Albino peacock. Nikon D3, 300/2.8 VR + 1.4x TC

7: Use single point continuous AF. Avoid the temptation to let the camera decide the AF point; it will almost never focus on the eyes, and certainly won’t be able to recognize animal faces (except perhaps some chimpanzees.) Continuous AF is necessary because your depth of field is razor thin; a little movement to and fro either by you or your subject can move focus dramatically.

_N212242bw copy.jpg

A thoughtful scratch. Nikon D200, 300/2.8 VR + 1.4x TC

6: Shoot in bursts. Two reasons for this: action usually unfolds in a sequence, and the first image may not be the most interesting; secondly, if you’re using a borderline shutter speed, then the burst helps to negate the effects of your finger pushing the shutter (and also camera). The first and last shots will usually be blur, but the middle group will be sharp because you didn’t have to move your finger in between.

_N210426 copy.jpg

Stealth duck. Nikon D200, 300/2.8 VR + 1.4x TC

5: Focus on the eyes. With all living things, the eyes are the key to the soul. I can’t explain why, but everybody knows that a portrait with the subject looking at the camera is a lot more powerful than one where you just see the back of the person’s head. The same goes for wildlife. Better yet if you can get a catchlight in the pupil, be it the sun or a very small fill flash.

_N208281 copy.jpg

Caught in the act of lunch. Nikon D200, AI 500/4 P

4: Have support. I don’t mean a sherpa team or an agony aunt. The longer the lens, the more support you’re going to need. A 0.1 degree camera movement with a wide lens covering 100 degrees horizontally is going to produce 0.1% blur, which you can probably get away with on a small print; but an 0.1 degree camera movement with a 5 degree field of view – corresponding to a 500mm lens – is equivalent to a whopping 2% blur. That shot will be so bad it might as well be completely out of focus. A gimbal head and solid tripod legs are great, but not very mobile. What I prefer to do is use a stout carbon-fiber monopod and rest my arm on the top of the lens to tension the system; if I’ve got something convenient to lean on, then I’ll use a bean bag to support the lens. This gets worse as your lenses get longer – I normally used an old manual focus 500/4 with 1.4x converter on DX, meaning 1,050mm equivalent. Handheld, this is an impossible combination to aim and hold, let alone get a steady shot with. With the monopod technique, 1/50s was routinely possible.

_7030609 copy.jpg

Angry cassowary. Olympus E-410, Nikon AI 500/4 P + 1.4x TC

3: Know our subject. Do your research, learn behavioral patterns, feeding patterns and anything else such as favorite watering spots or trees; the more you know about your subject, the easier it will be to find it and go unnoticed. Also, identify rare or unusual behavior – further adding something unique to your image.

_1D31619 copy.jpg

The bird with the sun hat. Canon 1D Mark III, 500/4 L IS

2: Patience, patience, patience. The rarer your subject, the longer it’s going to take for you to a) find it and b) get into a position where you can shoot it, or where it stays still for long enough for you to get a good image. Give up and call it a day only when you absolutely can’t stand waiting any longer; some of the most stunning wildlife images – think of the BBC Planet Earth series – were only captured after years of waiting.

_MT70034bw copy.jpg

Dancing flamingoes. Nikon D2H, 55-200/4-5.6 DX

1: Be ready and stay alert. Usually most interesting action happens in a split second; if you’re not ready with your settings fixed and your finger on the shutter, you’re going to miss it. This one seems to conflict with #2, but it really doesn’t; it’s what makes wildlife photography so difficult. Endless waiting, but the need to be vigilant. In the end though, the results pay off.

Part 10: Macrophotography

_7051614 copy
Lange Datograph. Nikon D700, 60/2.8 G

10: Watch your reflections! Every time I shoot something polished and reflective, I keep thinking of this viral internet meme called reflectoporn. Don’t google it. You have been warned.

_7053570bw copy
Jaeger Le-Coultre Gyrotourbillon 2 tourbillon. Nikon D700, 60/2.8 G with 72mm extension.

9: Use bellows or extension tubes to get more magnification. I’ve got both; remember you need to compensate exposure for light loss as your magnification increases. The Nikons do this automatically, but most other cameras don’t. Macro lenses and extension tubes/ bellows work great; make sure they’re high quality items because cheap ones will have non-planar mounts, and result in odd distortion. Note that some lenses won’t work with bellows or tubes because they either bring the focal point inside the rear element of the lens, or the lens design isn’t compatible because the focusing elements are internal.

8: Diffraction vs. DoF: a tradeoff. Pick one. As you stop down more, your DoF increases; but go too far and you also start to lose resolution because of diffraction. Exactly when this kicks in depends on your focal length and the pixel pitch of your camera; on the D700 with a 60mm lens, it starts around f22 and becomes very noticeable by f32. There are a couple of solutions: use a shorter focal length – the 35 ASPH FLE gives me more DoF by f16; or use a tilt shift lens.

_N201289 copy.jpg
Ants are skittish. Don’t get too close. I’ve had bugs jump on my lens before. Nikon D200, 105/2.8 VR

7: Working distance is your friend. There’s more room for lighting, and less chance of disturbing the subject (especially for those of you who shoot small bugs or insects). For product shoots, since you’re further away, reflections are smaller – and thus require less retouching.

_7055968 copy
Speake-Marin Immortal Dragon. Nikon D700, Zeiss ZM 2.8/28 Biogon

6: Macro lenses are used for macro work for a reason. That’s because they’re optimized for near subject distances; the plane of focus is flat and they have correction for common aberrations (spherical, lateral CA, LoCA) especially close up. With a normal lens, as you get closer, the aberrations and distortions get more and more obvious – which is why you don’t want to use a normal lens and extension tubes. There are two exceptions: when you have no choice, and when using certain particular lenses. A good example is the Leica 35/1.4 Summilux-M ASPH FLE; who’d have thought a documentary/ reportage lens with a 70cm near focus limit performs spectacularly on a D700 with extension tubes?

5: Continuous light sources are good. Not for primary lighting, but for helping focus and composition. Better yet if you mirror your lighting position with the secondary lights. I use a pair of 120 LED video light panels.

4: Use DOF preview to check your composition. DOF preview? Composition? How are there related? Simple: as you stop down, your composition changes again. And there’s a big difference between f2.8 and f22 at macro distances.

3: Clean your subject well! The better the lighting, the more uniform the subject texture, and the higher the magnification, the more dust you’re going to see. It’s much easier to clean the real object than try to do it in photoshop.

2: Set magnification, not focus. What’s the difference? Each lens gives a certain magnification ratio for a particular focus distance; if you focus first (or only focus) then you’ll find the composition changing – especially at the borders – as the image snaps into focus. I decide how much of the subject I want to cover, and then move the camera to focus. This is especially important at high magnifications – I work all the way up to 6:1.

1: Keep your exposure times short. You’re going to be wondering how. I use a flash and the highest sync speed the camera supports; because you’re stopped down and at base ISO, 99.9% or more of the light comes from the flash. And flash times – even at maximum power – are less than 1/1000s usually. Lower power ratings are even faster – this is more than enough to stop camera shake even at very high magnifications. The upshot? I don’t use tripods; they’ve been relegated to holding my flashes! I value the freedom of composition given by handholding the rig. The one exception to this rule is when I need to do focus stacking.

Long lens technique and tips

_3032710 copy
Snow duck, Hokkaido, Japan. Nikon D3, 70-300VR

Today’s article is going to be a little bit out of character for me – one of my great photographic passions used to be birding and wildlife; I don’t know how I got drawn into it, but my neighbor (and Photoshop guru, illustrator Gordon Hurden) happening to be on probably had something to do with it. I gladly spent my weekends in humid swamps, with nothing but mosquitoes and bugs for company; fortunately I managed to avoid dengue despite averaging at least a dozen bites from every session – inevitably on the tiny slivers of skin I’d forget to cover in repellant. I learned three important things from this period in my photographic career: one, patience and timing are everything; two, know your subject; and three, how to handle a long lens.

_D3T1396 copy.jpg
Eagle-Hawk. Nikon D3, AFS 300/2.8 VR

The first thing I can’t teach you, unfortunately; the second requires self-study, and the third is the subject of this article. For the purposes of simplicity, I’m going to wear the hat of a wildlife photographer, and discuss exceptions/ applications to other types of photography (sport, landscape, macro) at the end of the article. But before we begin, there are some golden rules that need to be shared and explained:

_N213460 copy.jpg

Forget about hand holding: Sure, you might get off a good shot or two, but try hefting that thing around all day and not getting tired – even if you are built like Arnie in his heyday, you’re not going to be at all stable. Remember: the longer the lens, the higher the magnification; the higher the magnification, the more obvious a given degree of angular shake is going to be proportional to the size of the frame (angular frame coverage decreases as focal length increases).

You get what you pay for: Cheap, optically good, and fast: when it comes to long lenses, pick any two. There are no bargains in the super telephoto world, unless you count some of the older manual focus lenses; then you lose AF, VR and gain a whole load of weight (no carbon-fiber hoods and helicoids here). This also applies to heads, tripods and any other part of the system you can think of.

Size does matter: For small, nervous animals – some birds are a great example of this – you can never have enough millimeters. And more millimeters means more reach, but also more shake. More shake means you need to go up a size for tripods, heads, etc – anything that forms part of your imaging system and associated supports.

You may be perfectly stationary, but your subject isn’t: Even if your system is rock-solid and can give you a perfectly sharp image consistently at say 1/10s and slower, your subject is probably not going to be able to stay still for that long – don’t forget this when you’re trying to figure out why there’s still motion blur in your image: it may not be from your camera or tripod.

_N214856 copy.jpg

With that in mind, let’s take a look at the things we can do to minimize camera shake.

Increase shutter speed.
This seems like a no-brainer, but the inevitable tradeoff is shutter speed against noise: would you rather have a blurry image, or one that’s sharp but noisy? Personally, the latter gives you some options for processing afterwards, but the former may just land up being frustrating. Throw the 1/focal length rule out of the window: how slow you can go depends on your technique/ support system and subject – I limit this to about 1/60 with relatively lethargic birds, and 1/500 for hyperactive ones (hummingbirds are a good example). 1/60 also avoids the danger zone of most support systems, and You’re not going to be able to handhold a 600mm lens at 1/600s, so give up that idea.

_N212587bw copy.jpg

Mirror lockup.
Most the vibration in an exposure comes from either the action of depressing the shutter, or recoil from the mirror raising into position immediately before the shutter fires. The shutter itself is designed to be as light as possible with very little inertia so it requires little energy to move; it contributes relative little shake. Although mirror lockup (or at very least, a self timer) is a great way of removing this issue from long exposures, the main problem with wildlife photography and mirror lockup is that response is not immediate, and you’ll almost certainly land up missing the critical moment. The best way around this is to use live view, and fire the shutter that way – on most of the newer live view cameras (D800 and D4, for instance) the mirror doesn’t have to cycle before firing a frame; only the shutter fires, resulting in much lower vibration. Some cameras even have an electronic first shutter option (D4) which further lowers vibration. Needless to say, the mirrorless CSCs are the best type of camera for this kind of work thanks to their combination of reach/ crop factor and lack of a mirror; it’s just a shame that there are no serious long lens options currently available. (A good 300/4 wouldn’t cost that much and give 600/4 equivalent reach and speed – are any of the manufacturers reading this?)

_N212564 copy.jpg

Continuous AF, or manual focus
Long lenses have extremely shallow depth of field; if your subject (or you) move by a small distance, this is very obviously translated into the focal plane sand not covered by depth of field; you will need to either use continuous AF, and control the point used manually (hint: cover the near eye of your subject) or focus manually. I did most of my wildlife photography with an old manual-focus Nikon AI 500/4 P telephoto, which was both lighter than the autofocus versions, as well as being considerably cheaper.

_N208163 copy.jpg

Shutter technique
I mentioned the act of depressing the shutter earlier – jabbing vertically at the button is almost certainly going to ruin your exposure through photographer-induced shake; slowly stroke the button instead from left to right, or roll the pad of your finger onto it from right to left. Either way, be gentle. Curiously the position of the shutter on the top plate makes depressing it especially susceptible to causing camera shake; I don’t know why none of the camera makers have cottoned on to this and implemented a more vertical release instead – squeezing the grip would produce far less shake, and still be just as ergonomic, if not more so. The only cameras that come to mind with a nearly vertical release are the old Olympus C-8080 and to a lesser extent, the Leica S2 – none of which are at all suitable for wildlife photography.

Tripods
A good tripod is your best friend, and a must for prolonged telephoto lens use. Monopods are better for mobility, but lack the ultimate stability and require constant attention to keep upright – a tripod, on the other hand, is happy to stand by itself all day (unless attacked by a bear) and is far less fatiguing to use. It’s tempting to get something light – especially since you know you’re going to have to carry it to the shooting location, which might be quite far from your transport – but don’t fall into that temptation, even if some of the lighter tripods have higher load ratings than your camera system. The reason for this is small tubes – both in thickness and diameter – will be far less effective at absorbing vibration than larger ones, and smaller joins will always be less rigid. Again: you get what you pay for. Carbon fiber is preferable to steel or aluminum because of both weight and damping properties; the orientation of the weave helps with this. Wood is also another option, but a bit heavier and not so happy with moisture. I highly recommend the Gitzo 5-series systematic tripods for serious telephoto users.

_N209570 copy.jpg

Monopods
If you need to run and gun, or are shooting with better light, or don’t plan to be out for long, then consider a monopod – it’s lighter, easier to set up, and more flexible. The same rules apply as for tripods – get the thickest, sturdiest one you can find; either attach it directly to the lens foot, or use a rigid monopod head (that permits only tilt) to minimize slop in the system. With the right technique, (see bracing below) I’ve been able to get critically sharp results from a monopod and 750mm equivalent lens at 1/30s. Note: monopods are not recommended if it’s windy; enormous lenses and their hoods tend to act like sails and windsocks and start to swing about a bit in the breeze.

_M223240 copy.jpg

Heads
There’s no point in spending a lot of money on a good tripod or monopod then letting it down with a lousy head – this is the critical portion of the support system. The most important thing is that the head must not be able to suddenly unlock and let go of your lens; this will make it both highly likely to result in an expensive accident, and difficult for you to adjust framing precisely. At very least, use a ballhead with tension control; I like the Manfrotto 468MG Hydrostat series. Ideally though, you probably want a gimbal head of some sort; this allows you to leave the system unlocked (providing you’ve mounted the lens at its balance point, of course) and simply aim the camera like a good artillery piece. Monopods should either have no head (screw the top of the monopod straight to the lens foot) or a dedicated monopod-only head to provide tilt. And this may sound stupid, but don’t forget to lock down the rotating collar on the lens – if it didn’t have any play in it, you wouldn’t be able to turn it. But at the same time, that play is death to stability.

Beanbags
If you have something to lean on, like a tree trunk, vehicle door or a wall, a beanbag can be an interesting option because it’s both stable and allows for a range of positioning; the beans mould to the shape of the lens and absorb vibration. In fact, this is one of the most stable support methods available. A cheaper (but heavier) alternative is a sack of rice. Just make sure you don’t let go of the lens, because it’s not attached to anything…

_M80_DSC4930 copy.jpg

Bracing
Bracing the camera lightly against your forehead via the eyecup is also a very effective way of dampening motion, because it couples it to the greater mass of your body. This is critical for monopod users, and of less importance for tripod shooters. In addition, if you’re using a monopod, it’s a good idea to put a little pressure on the monopod to keep everything under tension; hard to describe but what I usually do is stub one toe into the monopod’s foot, hold the camera at the grip and put a hand over the attachment point of the lens, whilst pushing forward slightly on the whole rig. This anchors the monopod firmly to the ground, as well as preventing the end of the lens from wobbling.

_N210426 copy.jpg

Breathing techniques
Similar to bracing, this is of importance to monopod users, but less so for tripod users as you should be shooting with the head locked down, and the entire setup static. Monopods are never static by definition, so you need all the tricks in the book to maximize stability. Don’t hold your breath when you shoot; this actually increases your heart rate over time. If you’re using a long enough lens – around 700mm and up – and hold your breath and stabilize the camera against your forehead/ eye socket, you’ll actually see the finder jump a little every time your heart beats. This is obviously counterproductive. The best technique to maintain an even heartbeat (shared with me by a competition pistol markswoman) is to exhale slowly when firi…oops, I meant depressing the shutter button.

_7190026 copy.jpg

Burst shooting
Since we’ve already established that mirror lockup is not practical for wildlife photography because of the lag involved, the next best thing is to shoot in three-shot bursts – this helps with both finger-induced motion (your finger is static for the middle burst) and mirror-induced motion, and works best with high frame rate cameras. The idea is that the camera will be displaced during the first frame, stay there during the second, and move back to the rest position during the third (where you lift off) – all I can say is that it works.

_7030609 copy.jpg
Cassowary portrait. Olympus E-410, Nikon AI 500/4 P

Stabilizers
Optical stabilizers work much better than sensor-based ones when using long lenses – this is because being at the nodal point of the optical system, they can correct for a much greater range of angular motion. However, they have their limitations – above a certain shutter speed threshold, stabilizers should be turned off; they simply don’t react fast enough and can actually cause double images. If you’re locked down on a tripod, they should be turned off too; these systems have a tendency to overcompensate for small movements of the kind that might be experienced on a tripod. Finally, although they can reduce camera motion, they can’t compensate for subject motion. Most of the time, I shot with stabilizers off.

_7020985 copy

Application to sport photography
Most sports are shot at high enough shutter speeds (to freeze action) that a monopod is sufficient, stabilizers aren’t really required, and although the refined techniques described above can help, they’re not strictly necessary until you start to get into the borderline 1/500s region – (due to the necessity to freeze fast action). Tripods generally get in the way and don’t allow the photographer to respond fast enough to changes in action.

_M102965 copy.jpg

Application to landscape photography
Although landscape photographers tend to not use such long lenses, a sturdy tripod is still recommended especially if long exposures are required; here mirror lockup (or at very least, the self timer) will help immensely with stability. Most support systems have issues around the 1/10-1/50s region; try and avoid this if possible, especially with longer focal lengths.

_3024681 copy

Application to macrophotography
At first glance, this may seem out of place, but in reality, macrophotography techniques are quite similar to those for handling long telephoto lenses; stability is paramount, and the smallest camera movement is hugely magnified. The main difference is your ability to control subject lighting with flash; this allows you to freeze motion (both camera and subject) through an artificially short exposure time – limited to the actual flash duration. All of the tripod-based techniques described above are useful to the macrophotographer; I can’t think of any situation in which a monopod would be useful.

Teaching update: Photoshop workflow DVD, August Email School intake

1. By popular demand…presenting Ming Thein’s Introduction to Photoshop Workflow DVD!

Thank you to everybody who participated in the earlier survey on whether a DVD covering my Photoshop workflow would be useful – it seems that nearly a thousand of you thought it would be, and that’s more than enough justification for me to produce one. I’m just sorry it’s taken this long – commercial work and everything else gets in the way…

However, I’m pleased to announce that the DVD is finally complete and available for sale; it covers:

  • A basic explanation of the working environment of Bridge and Photoshop, following CS5.5 (CS3,4, 5 and 6 are similar; I don’t use any tools here that aren’t available in the other versions, so it’s a very flexible workflow)
  • A runthrough of the functions of Camera Raw
  • My personal workflow – if you’ve ever wondered what my postprocessing process is, or how I get the style and look you see on the site and in my commercial work, this is for you.
  • Several end to end processing examples – I’ve picked a number of files that I’d consider difficult or processing-intensive to use as step by step walkthroughs.
  • The Camera Raw portion – where about half the work is done – also applies to Lightroom and Photoshop Elements, too. The buttons may be different, but the fundamental principles of tools don’t change between software – dodge is dodge, burn is burn, and curves are curves.

Total runtime is about 1h 15min.

Checkout now via PayPal

This will be the first in a series of many DVDs in which I’ll spend more time detailing and explaining the various functions of Photoshop and their application to photographers, but it makes the ideal starting point for anybody who would like to get started in serious postprocessing, or perhaps are wondering why their images lack that punch and sparkle.

Please note – for KL residents, happy to do MEPS – please send me an email to make arrangements.

2. Email School of Photography August intake

I’ve now cleared the pipeline somewhat, which means I can take on a fresh batch of students for my Email School of Photography – more details here. It’s a unique, fully-customized correspondence course tailored to your skill level and photographic objectives – learn what you want to learn, at your convenience. So for all of you who were on the fence, now’s the time to sign up.

The course is just US$800 for ten sessions including a detailed portfolio review; once again payable via paypal to mingthein2(at)gmail.com.

Thanks in advance for your support – all these little things help me keep producing content and keep this site running. MT

Depth of field and the importance of achieving critical focus

_7053043 copy

Your plane of focus determines more than just what’s sharp and what isn’t: it directs the eye of the viewer to the subject, too. The shallower your depth of field, the more exaggerated this becomes – to the point that with a very shallow DOF lens, a close subject and far background, you really won’t be able to identify what the background actually is.

_M8_L1012158bw copy
Jazz time. Leica M8, 35/2 ASPH

All the more important that you choose the right plane of focus, then.

From a compositional point of view, the obvious thing would be to ensure all of your subject in focus – or is it? Not necessarily – sometimes you need just enough of it to be identifiable, and the rest can be merely a suggested impression. Take the eyes in a portrait, for instance. You don’t need to have the ears and hair in perfect focus, too. Less obvious is the need for context: today’s photographers seem to be fixated on achieving ever shallower depth of field, not knowing that in the past, achieving sufficient depth of field was a huge struggle that required the use of camera movements, long exposures, enormous lights and tiny apertures (I don’t know if any readers remember or have heard of Ansel Adams’ f.64 club – so much for ‘f8 and be there’). Part of the problem was the insufficient image quality of smaller media; the other part of the problem was the psychological conditioning of observers and viewers: before photography there was drawing and painting, and neither of those had any such thing as bokeh.

Rain and traffic. Leica M9-P, 50/0.95 ASPH

I used to be one of those chasing ever faster lenses – for the simple reason that earlier digital cameras were frankly pretty crap when it started to get dark – higher ISOs were all but unusable. If you couldn’t use an tripod (reportage work, for instance) then you had no choice but to accept grain (compromising image quality), use a flash (compromising ambience and context) or use a faster lens.

Fortunately, we now have sensors good enough that we don’t always have to shoot at f1.4 the minute it gets dark; we can do so because we like the look, but not because we have to – and that’s important, because it means we can choose just how much context* to include in the shot. Moral of the story: think very carefully about how much of the image needs to be in focus to tell the story effectively: too little, and you lose context because the subject has no stage; too much, and you lose focus and isolation, because the subject may not longer be as separated from it environment.

*By ‘context’, I mean background that isn’t subject. If your entire shot is subject, then there’s no context, of course.

_7015246bw copy

This brings me to the second portion of this article: focus. It might sound obvious, but ensure your subject is in focus. The non-obvious bit is that there’s in focus, and in focus. The difference is obvious at the pixel level: are you seeing single-pixel detail (or near enough, to the resolving limits of your lens/ sensor combination)? If you’re not, go back and try again.

It matters for two reasons: there’s nothing more annoying than looking at a slightly OOF image, and you yourself will probably look at the photo later and think ‘if only…’; and then there’s the ever-increasing pixel density that makes it more and more difficult to achieve critical sharpness at the pixel level. The higher the resolving power of a camera, the more finely geared the focus mechanism has to be in order to achieve critical focus. In the film days, this wasn’t so much of an issue because the ‘sensor’ had some thickness to it – the emulsion was of a fixed depth – however, with digital sensors, this ‘depth’ is all but nonexistent – so an image tends to snap in and out of focus fairly abruptly, with very little acceptable transition zone – a zone that gets increasingly narrow as your depth of field decreases.

_M9P1_L1011571 copy
Just enough context. Leica M9-P, 35/1.4 ASPH FLE

The reality is that with modern lens and camera designs, camera shake aside, your ability to focus has by far the greatest impact on the resolution and perceived sharpness of an image. It’s actually much more difficult to achieve critical focus with a fast wide lens than a fast long one – reason being that the transition zone between in and out of focus is far more gentle; an increasing reliance on contrast detect AF rather than phase detect AF does’t help, either.

Fortunately, there are many things you can do to maximize your chances of getting a positive hit. I’ll go through them for each of the common camera types.

Compacts

1. Half press to focus, and gently release. You’d be surprised how many people just jab at the shutter button and wonder a) why their camera is slow and b) why images are blurry. The former is because the camera will take some time to find focus; the latter is because either it didn’t find focus properly (the electronics told it to trip the shutter when focus was acceptable or because of the jerk caused by the finger-jabbing motion and recoil.
2. Pick a high contrast subject. All compacts (except the Nikon 1 and some Ricohs, but those are all hybrid systems anyway) use contrast detection to determine when the image is in focus or not. The lens is racked back and forth until the portion of the image under the selected AF box reaches maximum contrast; this may or may not correspond to what you’ve selected. So, to be safe, select a subject with good contrast.
3. If in doubt, stop down a little – but not too much. Stopping down gives you more depth of field to cover focusing errors; on a compact with very short real focal lengths, you’ll find that f4 (or f5.6 at maximum for larger sensored cameras or longer focal lengths) is probably enough to ensure everything is in focus; any more than that and you’ll be seeing a reduction in sharpness due to diffraction.
4. Turn off that AF assist light. Not only is it hugely annoying and conspicuous at night, I find that it also tends to give a lot of false positives.
5. For moving subjects, continuous AF is nearly useless. The only way to reliably hit a moving subject is either to rely on your extended DOF and hope single AF is quick enough to nail it, or use trap focus by pre focusing on a certain point, and waiting for your subject to arrive.

_3100_DSC0957 copy
Crossing. Nikon D3100, AFS 85/1.4 G

DSLRs

1. I repeat again: half press to focus, and gently release. The same applies for DSLRs and compacts.
2. And again: pick a high contrast subject. Phase detect AF sensors also like high contrast subjects – preferably something with either horizontal or vertical lines, depending on the orientation of your AF sensors.
3. Don’t let the camera do the choosing. Pick your AF boxes manually. If you don’t, you have no idea what the camera will focus on – it’s generally the closest thing in the frame, but that might not be what you want it to do. Especially if you’re shooting with a very shallow DOF lens.
4. Use continuous AF mode. Again, especially for shallow DOF lenses, a few millimeters of subject movement or photographer movement to or from the subject can affect sharpness greatly – to avoid this problem, use continuous AF mode and only lock focus if you’re absolutely certain you’ve got what you want. (A popular alternative is to put AF-ON on a separate button. I personally use that button to lock focus, because generally it’s easier to use one finger to activate AF and shoot off the shutter button alone, rather than two) And without saying, you HAVE to use continuous AF on moving subjects; make sure the focus box always tracks the subject.
5. Check your focus calibration. Set up the camera on a tripod, with an angled static target (I recommend the LensAlign) that lets you see if you’re focusing on your intended point or not. Adjust your AF Fine Tune settings if you have them, until you can reliably achieve critical focus. Do this for every lens you’ve got.
6. Get your mirror aligned. If you’re manual focusing a lot, you’ll want to get your mirror aligned so that what you see in the finder is the same as what the sensor sees – what this effectively does is adjust the rest position of the mirror so that the distance from mount to sensor is exactly the same as mount to focusing screen, over the whole frame.
7. Use a split prism or micro prism screen. Remember the half-circles in the middle of manual focus film SLR viewfinders? Those were focusing aids called split prisms, which let you see very quickly if something was in focus or not – all you had to do was turn the focusing ring until the verticals aligned. Why they’re no longer standard equipment on DSLRs these days is beyond me. Why they’re no longer available even as accessories, except for some third party companies, is even more mind boggling. The standard screens have a very narrow scatter angle, which means that there isn’t much difference in brightness between slow and fast lenses – great for kit zooms, but not so great for determining critical focus with very fast lenses; they lack the required snap. If you don’t believe me, try using the DOF preview button at f1.4, f2 and f2.8 – you’ll probably see no difference in the viewfinder.
8. Don’t trust the focus confirmation aids. The dot (Nikon) or beep (Canon) is somewhat misleading because there’s a range to ‘acceptably in focus’ – and the extremes of that range are pretty wide. It’s a guide only, not an absolute.
9. Use magnified live view and a tripod for absolutely critical images.

Rangefinders

1. The most critical portion of the focusing system is the rangefinder. It is impossible to emphasize how important a perfectly aligned rangefinder is – especially when using fast lenses. Remember also that you have no way to visualize the focus plane. So: make sure your rangefinder is properly calibrated for the lenses you use – each lens will be slightly different because of cam wear, alignment and a whole load of other factors. Do not attempt to do this yourself, because there are four adjustment points – one each for near and far limits, one for travel, and one for vertical alignment. Not knowing which one does what can result in a bit of a disaster. Since there’s a feeler cam that always interacts with the focusing cam on the lens, the calibration can, and does, drift after a while, so check it annually or so if you use the camera frequently.
2. Clean the RF and VF windows! Dirt + smudges + oil = low contrast = difficulty in focusing.
3. Use a magnifier over the viewfinder if you’re using longer lenses. This helps by enlarging the central portion of the frame that contains the RF patch (at the expense of the outer portions) – you’ll find that since the RF patch occupies a large portion of the frame, it’s difficult to see exactly what’s in focus and what isn’t without the magnifier.

Finally, remember the higher the resolution camera you’re using, the more critical focusing becomes – don’t go out for an upgrade of either camera or lenses until you’re sure that you’re getting all you can out of your current one. MT

How to tell if your D800/ D800E/ D4 has the ‘left focusing problem’

I’ve been asked this question more times in the last few days than I can remember: ‘does my D800/ D800E/ D4 have the left side focusing problem?’

Here’s how you can tell.

1. Pick the widest, fastest lens you own. A 24/1.4 is ideal.
2. Shoot it wide open, with the camera on a tripod, AF set to AFS single point.
3. Shoot a set of images at extreme left, center and extreme right, defocusing the lens manually between shots. Use viewfinder AF. Pick a subject about 2m away.
4. Without moving the camera, do the same but in live view. (This is so the camera focuses exactly on the sensor).

5a. If there is no difference in sharpness in AF and LV modes between the points across the frame, then you’re fine and don’t have a problem. (But you might of course find the edges worse than the center; that’s normal. LV and AF focused shots at each point should look exactly the same in a correctly calibrated camera.)

5b. If LV is sharper than AF for all frames, then you need to use AF fine tune and try the process again.

5c. If the LV shots look sharper for only some, but not all, of the points, (e.g. right and center points look the same for AF and LV, but your left point is much sharper in LV than AF) – then you have the asymmetric focusing problem and your camera has to go back to Nikon.

You might also find this article useful on how to use AF fine tune.

And with that, I’m off to send my camera in for the fix. Will report back later (or tomorrow, whenever it’s done)…MT

Common photographic mistakes by beginners, amateurs and pros – and how to avoid them

_M9P1_L1004981bw copy

Beginners: Ever wonder why your photos don’t look ‘professional?’ Amateurs: ever wonder why you lack consistency? Pros: Ever wonder why you lose your edge or drive? Wonder no longer. This article deals with some of the most common oversights by photographers of all kinds, and how to avoid them.

Beginners

The missing subject. If it’s not obvious at a glance what is the subject of your image – i.e. what the photo is actually about – then you should probably ask yourself why you took the picture in the first place. If the answer was ‘because of the X’, and the X is not obvious, then you need to try again. The subject in a photo should stand out – by contrast, by color, by light, by motion, or by focus. In exceptional cases it’s possible to make it stand out by not having it, but this is very, very rare and requires perfect use of contextual information to allow the viewer to make inferences about what should complete the scene.

Poor perspective use. Pick your perspective before your angle of view. Wide angles are used to emphasize foreground subjects, telephotos to de-emphasize them with respect to the background. Don’t use a wide angle to ‘get more stuff in’ the frame, that will just result in boring images. Similarly, telephotos are not for ‘getting closer’.

Being stuck in the wrong gear. This includes the entire suite of woes of technical errors – exposure, focus, camera shake, white balance etc. Usually due to the driver relying too much on the camera to do the work for you: it will never get it right because there is no way the camera can know what the photographer intends to do with each image. You will have to take control somewhere along the line in the imaging chain in order to create the image you envision in your mind at the time of capture, and it’s better to do it closer to the capture process to minimize the subsequent amount of image quality degradation.

Amateurs

Worrying too much about gear. This usually takes the form of hauling around everything you own for every shoot and believing a new piece of equipment will solve some deficiency in your images that can almost always be traced back to photographic skill, or more specifically, the lack thereof. If you carry too much stuff you’ll always be second-guessing your choice of lens or camera. And if you keep buying new gear, you’ll never master what you’ve got – and be at a disadvantage because you can’t control your equipment. Before buying new gear, make sure you know exactly what it is with your current kit that is the limitation, and that it will resolve the problem – otherwise you’ll have both wasted money and compromised your photography. However, if you’re just a camera collector, disregard this item. In fact, disregard this entire post.

Intrusions and truncations into frame edges. With 100% finders being commonplace, there’s no excuse for parts of the subject being cut off at the edges, or obviously contrasting distractions intruding into the frame – like tree branches or phantom limbs, for instance.

Color issues. Odd white balance, or objects in the frame that are obviously the wrong color can create some interest in an otherwise boring scene – or things like that can just be jarring if they’re too far off the mark. This is especially important for skin tones or food. If you’re not sure what the correct white balance is, either adjust it accordingly with the eyedropper tool when converting the raw file, or manually white balance with a gray card. Don’t leave the camera to do it on automatic – if a channel gets clipped, the information isn’t recoverable. This is especially obvious with jpegs due to the limited tonal range available in the first place.

Black and white contrast issues. Amateur black and white generally tends to be too flat or too contrasty. The latter results in a loss of highlight and shadow quarter tones, resulting in an over-graphic representation of the subject and not enough tonal range to differentiate the subject from the background; the former is just dull and uninteresting to look at. It’s like knowing the chef had twenty different ingredients to make a meal, but he used only the gray, monotonous-tasting one.

Poor use of natural frames or leading lines. These little ‘helpers’ are to be found all over the place – the converging perspectives of a long hallway are a great example of this. They can help to draw your eye to the subject, but they can also lead your eye away from it if you put the subject anywhere else by the confluence of these lines.

Center-only composition. Few images work well with the subject dead-center or nearly there; the more dynamic images always have a bit of space before or after – I like to think of it as the anticipation or the aftermath. All cameras these days have more than one focusing point. I hear they even let you pick which one!

Lack of balance. I did say just now that center-subject compositions are boring; that’s because they mostly are. But at the same time, you can’t have frames where all of the action happens in say the bottom-left corner and the rest of the image is empty. Visual balance is a tough thing to describe, but fortunately it’s one of those properties of an image which is instinctively easy to recognize.

Incorrect use of depth of field. Too little, and the picture becomes about the bokeh – most of the images shot with the old Leica 50/1.0 Noctilux are like this – I can never understand why people gush over a picture of a boring fence or pile of bricks just because it exhibits swirly bokeh; to me it says nothing more than ‘I rely on my gear to create a style for me because I have no imagination!’ It is, of course, a tool – used well, it can enhance an image. Used poorly, well, you’re just another camera collector who takes pictures of fences. Notice I haven’t said anything about too much depth of field – you can always compose to use this to your advantage, because any secondary element of context helps to tell the story. However, the converse is also true – there’s no context in an abstract wall of blur. Conclusion: I’m beginning to think there’s a just right amount of bokeh for every scene – or at least a range; just enough blur to help you focus on the primary subject, not too much to remove all the context.

Poor timing and not being prepared. I see plenty of shots that I call ‘near misses’. This is when the idea is there, the technical execution is well done, but the timing is off – always caused by a moving element that’s out of position. There are two elements to getting this right – practice, and practice. You need to have some ability to anticipate what’s going to happen next; you also need to have an instinctive feel for how much lag your camera has between depressing the button and the picture being taken. And the only way to make this intuitive is by shooting and getting accustomed to it.

Professionals

Getting stuck in the creative rut. Not pushing yourself and relying on the same patterns of framing time and again may ensure you get the money shot, but eventually everybody else will be getting the same money shot, too. (Certain local celebrity wedding photographers where I live are notorious for this.) You need to be continually trying new things, improving and refining and always pushing. It’s an increasingly competitive industry, and a very visual one – if your images don’t stand out, then you’re never going to be a client’s first choice – they probably won’t even notice you from the rest of the pack.

Leaving the thinking to the client asks for and no more. This is related to the previous point – in fact, it’s the precursor to it. Clients come in a continuum: those who leave all of the creative freedom to the photographer, recognizing that the reason why they were attracted to your portfolio in the first place is because of your own personal style (these are the best clients of all) – to those that tell you exactly what they want, down to the last millimeter of positioning. The former type of client is rare; this makes it very easy to fall into being a contractor/ executor rather than being a creative.

Subcontracting out too much of the retouching and styling. Another related point comes in the form of an army of assistants and stylists. Given how much of the creative process is encapsulated in the post processing portion, it seems rather risky to leave the work to somebody else – even if they understand your original vision, chances are that it will take longer because there will be many revisions required, and in the end it may still not quite be what you initially envisioned. If you let this happen for too long, technology may move on to the point where you don’t even know how to achieve the desired end result anymore. And if your assistant or retoucher leaves, then what happens?

Not trying different subjects. I’ve had endless debates with various people in the industry on this topic – is it better to be a specialist and only shoot one thing, or a generalist and shoot everything? The reality is that it’s a bit of both. You have to be known for one thing – that becomes your go-to commercial support – but you need to be able to shoot many different types of subjects. There are two reasons for this – firstly, it lets you make more income from being able to offer clients additional services; the less obvious one is that shooting different things helps you to develop different techniques that can be applied across your particular subject of expertise.

Finally, there’s working too much. This sounds contradictory, but not taking enough time out to focus on personal shooting/ creative development can actually make you lose your creativity and consequently negatively affect your business. Fortunately when this happens, you’ve got less work and more time to experiment, so hopefully you do actually go out and do some personal shooting. I’ve definitely noticed that the more commercial work I do, the less I feel inclined to do personal work – I think this is dangerous because that’s probably the only time where you don’t have limitations imposed on you by your deliverables, and can let your creativity do its thing.

And on that note, I’m off for a walk. With a camera. MT

Some thoughts on reprocessing and revisiting images

Reprocessing
The difference of seven years of Photoshop skill: 2012 (left) vs 2005 (right). Mandarin duck; Nikon D2H, Tokina AF 80-200/2.8

From day one, I was told by every serious photographer two things: one, don’t delete anything because opportunities never come twice, but storage is cheap; two, shoot raw, and keep your raw files somewhere in an archive. Or at very least, keep your original jpegs if your camera doesn’t do raw.

I only recently started doing the former: I keep all of the raw files from a commercial shoot, and then send a contact sheet off to the client to let them pick the ones they want retouched – usually between 10 and 50%, per whatever the commercial agreement was. The rest stay in the archive in case they come back later and want to license additional images, or I need to composite in bits during the retouching. For my personal work, I cull ruthlessly – the rationale and the methodology was previously covered in this article.

_DSC8648b copy
Venice, 2004. Nikon D70, 24-120VR

One of the more popular justifications given for being the image-hoarding equivalent of a packrat is that you might want to go back and reprocess your files later once technology or your technique improves, so you can get more out of the original image. This makes sense from a logical point of view, but from a practical standpoint, if you’ve improved that much as a photographer it’s probably because you’re out there shooting new stuff and refining both the shooting and processing portions of your technique. In short: I’ve never gone back and reprocessed anything. Well, there might have been a couple of exceptions when an image was licensed to a client and adjusted for print or to the client’s taste, but nothing more than that. I honestly don’t have time to reprocess my personal work.

_DSC8648-2012 copy
Venice, 2012

However, I suppose we could all find time to do things if we thought they were important enough. And this brings me to the biggest argument against reprocessing images: your artistic vision for that particular image, or what you saw in that particular scene, will never be stronger than at the time of shooting. It just fades gradually as time passes; this is just a consequence of the way the human brain works: we forget things over time. And unless you suddenly look at an image again later and find something that bothers you hugely, you’re probably just going to go with whatever you thought was best at the time.

_MT39141bw copy
Courchevel cloud, 2005. D2H, Sigma 70-300/4-5.6 APO

However, in the interests of academic curiosity, I’m going to do some reprocessing for this article. I don’t know how it’s going to turn out: I’m writing this philosophical portion of the article before doing the work. Frankly even finding shots that meet my compositional standards is tough, because I (hope, at any rate) have moved on significantly in my photographic abilities since these images were shot. There’s no point in reprocessing something from last month, because I don’t think you’ll see any difference in the before and after – one’s style changes slowly, like a tree growing. But one’s style is also defined by the way you shoot, and there are things I do routinely now – for instance, cinematic, very shallow DOF in low light – which I couldn’t physically have done back then, because the equipment didn’t exist.

_MT39141-2012 copy
Courchevel cloud, 2012.

The archives have been raided, and yielded a number of images. In some cases I’ve had to use the original JPEGs as a starting point because I didn’t have raw files; this is obvious in the lack of file quality and noise. There’s not a lot I can do about that, unfortunately; 8 compressed bits of tonal information can never be made into 16 complete ones. You’ll also see in some places I disagreed with my original processing choice of B&W vs color, and even the final crop – I guess as one’s style and eye evolves, we see different things in the same image. The eagle-eyed of you will also notice small corrections to composition via distortion, cropping or stretching; I normally do these things today, but I’m sure I wasn’t doing any of it at the time. Similarly, dust/ speck cloning was something I never bothered with. I’ve picked a wide range of subjects, too. I’m going to post the final state I arrived at back at the time – usually a mildly edited jpeg – and the reprocessed, 2012-version. I would highly encourage all of my readers to share their thoughts on which they prefer, and why; let the comments section be a forum for discussion. I’ve also provided some thoughts below on each individual image.

_M227904-2012 copy
Nikko station, 2012. There’s a lot of empty space in the top portion of this image, especially the overexposed window at top left; it threatens to imbalance the composition – hence switching to a 16:9 crop. The original colors in the scene were delicate and tonally interesting, so I opted to rebalance for true color instead of do another monochrome conversion.

_DSC8280b copy
Piazza San Marco, Venice, 2004. Nikon D70, 24-120VR

_DSC8280-2012 copy
Piazza San Marco, Venice, 2012. This is one of the very early images from my DSLR career; up til this point I’d been using a super zoom compact. If I’d known any better, I’d have used a different exposure time to retain more suggestion of people in the scene, or better yet, stacked many exposures. And f10 isn’t exactly the optimal aperture on the first-generation 24-120VR. Aside from the obvious color fix – this is much closer to the reality I remember than the original processing – verticals, horizontals and tonal maps have also been tweaked. I don’t think the composition is particularly fantastic, but gimme a break, I just started at this point, okay? :)

_M227348 copy
Kinkakuji, Kyoto, 2007. Nikon D200, 17-55/2.8

_M227348-2012 copy
Kinkakuji, Kyoto, 2012. You’ll notice there isn’t a lot of difference between the two; this was from a later period in my photographic career where my processing was both more refined, and I was shooting RAW (with all of the associated available adjustments) to hand. I didn’t change the composition, though I’m not 100% happy about the positioning of some of the edge elements in the frame; the majority of the change was to sort out the dayglo colors, and the horribly inaccurate foliage. It was a particularly hot summer that year; the image was shot in August, and the trees were looking a little dry and wilted – I think this is much closer to the reality I remember at that point.

_M215519 copy

_M215519-2012 copy
Scarlet Ibis, 2012. Not a lot of change; I punched up the color a little, because these birds are pretty darn striking in person. I don’t remember the color of the swamp, so I left it much as-is. Again: a late 2007 image.

_MT39064 copy

_MT39064-2012 copy
La Tania sunset, France. WHOA! You’re probably wondering what happened here – of all the images, this is the one which is the most different from the original. Aside from the obvious change in crop, I’ve now got the shadow recovery tool at my disposal, and better yet, an intimate familiarity with it. The problem I faced at the time was the sunset was a) both not very punchy and b) the native dynamic range of the scene was already quite challenging, meaning that making the highlight portion punchier would have sacrificed tonal detail in the shadows. At the time, I had no clue how to unblock it. I don’t remember the exact color of the the scene, but I suspect it was probably somewhere between the two images. Which one do you prefer?

_DSC8121bw copy
Venice, 2004. Nikon D70, 24-120VR

_DSC8121-2012 copy
Venice, 2012. At the time, I was influenced heavily by a number of ‘classical’ monochrome shots I’d seen in magazines; as a result, this street scene was instantly converted. What I failed to notice in the original – until now, fortunately I still have the original color jpeg – is that the light spillage from the shop windows at left actually give the image an interesting structure that’s lost in black and white because of the similarity of luminance values between the warm-lit stone and the regular stone. I’ve attempted to bring this back, however the limited dynamic range of the jpeg has led to less smooth tonal transitions than I’d be able to achieve with a raw file. Actually, working this ‘vintage’ jpeg reminded me a lot of dealing with iPhone files – imperfect color, blocked shadows, blown highlights, and a decidedly averse reaction to resizing.

_DSC8066b copy
Canal reflections, 2004. Nikon D70, 24-120VR

_DSC8066-2012 copy
Canal reflections, 2005. To me, reflections are juxtapositions. Our minds invert them subconsciously anyway, otherwise we would recognize them as the mirror images of their own selves; I usually take this further by treating the image as the real subject, and the subject as the abstraction – what’s the difference anyway, since all images are subjective and facsimiles of the real thing? Aside from that obvious flip, the verticals have been corrected, and the tonality smoothened out – especially in the water, so it looks more like liquid and less like a block of color.

_MT73080 copy.jpg
Mandarin duck, 2005. Nikon D2H, Tokina AF 80-200/2.8. For some odd reason Flickr won’t let me re-upload a modern duplicate of this image with the right border and matching image size, so I apologize. However, the original image remains the same.

_MT73080-2012 copy
Mandarin duck, 2012. Improved color accuracy and worked on micro contrast a little.

With all of the reworked versions, I’m not sure I can say that I 100% prefer the 2012 version over the originals – photography is very much the sum of the parts, and the interaction between the original framing and the processing is very much a large component of that. The processing methodology I currently use doesn’t really fit the vision I had back then, and vice versa. Score one for the argument against do-overs: you really can’t fix it in post; you can enhance an image, but not fix something that’s fundamentally wrong with the composition or lighting. Here’s another interesting idea for a future article – reprocessing somebody else’s raw files. Might provide an interesting insight into how much difference Photoshop really makes…MT

Video: A B&W workflow tutorial

After the series of articles on color and B&W – and of course the M-Monochrom review – I got a huge number of emails asking about my workflow for B&W conversion. I originally tried to put this post into a conventional text and image format, but gave up shortly after I realized it would be impossible. Instead, have a video! I don’t claim to be any good at video production (forays into this are are another topic for another day), but I think this should give you a good idea of how it all comes together. Excuse the lousy sound, that bit I still haven’t quite gotten figured out yet. I suppose I need some collar mics or something – the equipment buying never ends…

Anyway, enjoy the video. MT

Black and white conversion options

_3100_DSC0450bw copy
Water drops. Nikon D3100, 60/2.8 G.

I’ve gotten a lot of emails after the Leica X2 and M-Monochrom reviews asking about B&W conversion and processing; I guess the M-Monochrom announcement had a knock on effect on the way people started seeing things. It doesn’t make color cameras redundant for B&W work, though.

Let’s start by demystifying two things.

1. Certain cameras have certain particular B&W characteristics. True, but only if you use JPEG. If you are shooting RAW, they provide different starting points – this is from a tonal response point of view – but ultimately you can get a consistent look regardless of the camera. I know, because I do this all the time.

_DSF1170bw copy

2. There are benefits to a monochrome-only camera. True. The Bayer filter and subsequent conversion is an interpolation of neighboring pixel image data to extract color information; luminance information is lifted from the photosite. Any sort of interpolation will reduce tonal accuracy and increase noise, because the luminance value you’ve got is now an approximation instead of a true value. However, it’s fairly easy to see that whilst there are benefits to shooting monochrome-only, you can actually convert a color RAW file into a monochrome one, and lower the perceived amount of noise – though not to as low a level as a monochrome-only camera. If you have a poor interpolation method, then the luminance values can be affected too – once again, increasing the perception of pixel-level image noise in a color image. Bottom line: yes, lower noise, and yes, better detail.

_M9P1_L1014802 copy
Trees. Leica M9-P, 21/3.4 ASPH.

Also one of the images available in my print offer.

However, what you lose from a monochrome-camera is the ability to do control the relative luminance level of individual color channels. Why is this important? Suppose your color scene has a relatively small range of background tonal values, but your subject is a very different color. Its luminance may be the same as the background, but it stands out because of the difference in color. As we concluded in a previous article, this kind of image is a very bad candidate for B&W conversion off the bat, because you’d land up with something very flat-looking. (Real life translation: running out and buying an M-Monochrom isn’t going to solve your B&W conversion woes, but it will give you an interesting starting base – especially when it comes to noise and dynamic range. Those of you who don’t mind doing a bit of work, hold on to your normal cameras. And in fact, these techniques apply to the M-Monochrom too.)

_7006528bw copy

Actually, if you’re prepared to do some work, this not necessarily the case. It’s still possible to separate the subject from the background on the basis of luminance only; you just need to work a bit harder. You’ve even got a few options here. Park that thought for a moment, we have to introduce the basics of B&W conversion first.

_M8_L1022658bw copy
Shadows. Leica M8, Voigtlander 50/1.1

_5000935 original
A sample image for the purposes of demonstration for this article. This is the original file, converted from RAW, with all of the sliders set to zero. Olympus OM-D, 45/1.8.

The simplest method is to desaturate. All this does is throw out color information, and leave luminance information only. You are then free to do whatever you wish to complete processing of the file. After much investigation and experimentation, this is actually the method I use, coupled with another trick or two. Desaturation can be done in ACR (saturation slider, first tab) or in Photoshop (Hue/Saturation tool, then desaturate the master)

_5000935 desaturate
Straight desaturation. Note overall lack of contrast.

Slightly more complicated is the gradient map. You can use the standard linear black to white transition (press D in photoshop first, then add a new gradient map adjustment layer) – which gives very similar, but not quite the same, results as desaturation. Gradient maps with a straight gradient tend to be a bit more contrasty than desaturation. If you want to experiment a bit, it’s actually possible to put in intermediate control points into the gradient and bias it towards a high key (mostly white, black fades out faster) or low key (black stays for longer) look. What actually works here will depend on your image, however, so be prepared to do some fiddling. The good news is that if you use a new adjustment layer, the gradient is easily modifiable without having to redo your entire conversion.

Finally, we’ve got the channel mixer. Best used on the RAW file in ACR, this lets you decide how much of each individual color channel goes into making the final image. Note that the tool only uses the luminance components of each channel, and it’s additive; this means that color (and perceptual color) information is discarded. To make things even more complicated, there’s a separate B&W conversion adjustment layer in Photoshop itself that effectively does the same thing as the ACR conversion, but it only has six channels for you to play with instead of the eight in ACR.

_5000935 channel mix red heavy
Channel mixer via ACR, decreased reds; note how the subject (in this case, predominantly in the yellow channel) stands out more from the background.

Remember the conundrum of how to isolate a different colored, but similarly luminous, subject from the background from earlier? The solution to this is the channel mixer. You can increase the luminance of the primary color of your subject, and decrease that of the predominant background color; the converse also works. The problem comes when you’ve got a mixture of colors in both subject and background, and some of those are common colors. (Don’t get carried away though: remember that some images just don’t work in black and white).

This isn’t, the entire toolkit, of course. You’ll find that after this kind of conversion, things look rather flat. That’s because a lot of how the human eye perceives contrast and separation is dependent on differences in hue; obviously we have removed that, so we have to artificially put it back in again. Two of Photoshop’s tools will be your best friends here: the dodge and burn brush, and the curves tool. Understand how both of these things work, what the dos and don’ts are, and you can work magic with any B&W conversion. A tablet is also extremely helpful for these things, as it gives you precision control and feathering over your brush application. It lets you avoid hard edges, odd abrupt transitions, and permits highly precise editing.

At this point, it’s probably worth talking about plugins and filters. The former are either a set of Photoshop actions, or a separate program, that controls the conversion – specifically the luminance translation of each cool channel into a luminance value – and the tonal map of the final file. Whilst they are extremely popular and used by many ‘internet street photographers’ either to save time or because they are unable to get their desired results from a nuts and bolts conversion, I personally avoid them because they do not give you enough fine control, and even worse, everybody’s images that were run through that filter look the same. There is no personality or skill in that.

Photography is arguably art and very much down to personal taste. If you are 100% happy with the way those results look, great; I’m jealous of the amount of time you’ve saved in your workflow. However, claiming this is art is disingenuous; it’s like finding out Ansel Adams shot BW400CN (a B&W film designed to be run through a C41 color processing machine) and developed it at the local pharmacy – instead of Tri-X or Plus-X, controlling his development time and chemical composition, and then cutting precision masks to dodge and burn portions of his subjects.

_5000935 copy
That ‘arty’ high contrast, high grain look. It’s actually what heavily pushed Tri-X used to look like, but how many people actually know that firsthand?

There’s a second type of filer that’s useful, and in either form, it performs a similar function to the channel mixer – it either admits or cuts out light that’s of a certain range of wavelengths. The most common example of this is a physical red filter that goes over the end of your lens; the effect is dark skies, because very little of the blue spectrum passes through the red filter and onto the recording medium. It works with digital too, but you have to remember to adjust exposure accordingly, and obviously not use it in color mode. You can also replicate this effect digitally. Add in a new layer, make it one color, and then select the appropriate blending mode; then only do your B&W conversion. There are interesting results obtainable through this method.

_5000935bw copy
Final image, desaturation + curves + selective dodge and burn + second round of curves + slight palladium tone layer

If you pull back the B&W conversion layer slightly – assuming you didn’t directly apply the conversion to the image – then it’s also possible to use a color layer to create a toning effect; sepia or platinum is probably the most common. You can even use a graduated fill layer to provide a variable effect; this is especially useful for increasing the density of skies, for instance.

Personally, I prefer to shoot color and then convert to B&W; not because I can’t decide upfront how a scene should be presented, but because there’s a lot of flexibility in how I want to handle the conversion later to highlight certain aspects of my subject, or achieve certain tonal looks.

I’ll go into detail on my personal B&W workflow with an end to end example in a future article. MT

Chasing perfect color, and common myths about white balance

The previous article on the inexact science of color and emotion dealt with why color was important, and how we can use it as a tool to alter the mood and emotional response of the viewer of our photographs. This article explains how we get there.

Although highly saturated color is visually striking, and B&W images are timelessly classic and elegant, there are a lot of times when neither is appropriate or an accurate representation of the scene. I’ve recently realized that I like accurate color above everything else – saturation control then becomes a matter of seasoning to taste. Color accuracy is actually quite critical when it comes to things like food – if the color of cheese or lettuce is off, it just looks moldy or unfresh. This is definitely NOT good for commercial work! My recent work is what I’d call in a ‘natural’ style – the color, saturation and hues are as close to my perception and remembrance of the scene as possible. I’ll do some shifting of white balance to make things warmer or cooler as required, but not a huge amount because it can do some very strange things to tonal accuracy.

Skin tones are perhaps the most difficult to replicate accurately; this is because skin is both reflective of ambient light (easy for the camera to capture) and emissive – we’re warm, and there’s some passive IR radiated by warm objects. Although modern cameras have very effective UV/IR blocking filter packs, they also produce (in my opinion) slightly dead-looking skin tones. I actually liked the skin tones from the Leica M8 for this reason, which was notorious for having perhaps the weakest UVIR filtration of any camera on the market – to the point that to get accurate blacks you’d have to use a UVIR filter on your lens.

Other objects that are notoriously difficult to reproduce accurately are flowers, some animals, and some fabrics. Again – this is because of the way they interact with the near-UV and near-IR spectra, which affects the way our eyes perceive color (though we can’t see UV or IR directly unlike some animals). To date, there is no camera that accurately reflects the spectral response of the human eye – and I suspect it might be very difficult to make one, because the filter pack would have to be calibrated to transmit or cut out a certain amount of each wavelength. It’s much easier to make a filter that cuts out everything above and/or below a certain wavelength. Throw in the added complication of mixed light sources, and you’ve got a minor nightmare.

Colors. All of them. Which one do you balance for without shifting the others? Answer: focus on your subject – in this case, skin tones and blacks. Olympus E-PM1 Pen Mini, 45/1.8

So what can we do to achieve perfect color?

First clarification: we are not trying to achieve perfect spectral reproduction; we’re trying to achieve perfect perceptual reproduction. It’s not quite the same thing. Basically, you want to get to the starting point of being as close to what you remember seeing as possible, then work from there. That way, you know that all of your tweaking isn’t going to create some strange shifts in certain parts of the tonal spectrum.

White balance is inextricably linked to color. And there are some important things one has to bear in mind:

1. You have to get it right first time if you’re shooting JPEG. There just isn’t the tonal headroom in 8 bits to be able to make anything other than minor channel adjustments and not encounter posterization or weird hue shifts.

2. Manual white balance and a piece of paper are your best friends.

3. If you’re shooting RAW, white balance is less critical, but if you blow a channel, you’re not getting it back. Usually reds and yellows are the first to go. With earlier cameras, you might have to underexpose by as much as two stops to maintain tonal detail in the reds. I think it’s something to do with IR-sensitivity, the effectiveness of the filter pack over the top of the sensor, and how the red pixels respond very strongly to IR pollution.

Cigars are one of the most difficult colors to get right. I don’t know what it is about the tobacco leaf, but that rich, deep brown hue requires a lot of work to perfect. Nikon D700, AFS 60/2.8 G Micro

4. White balance does affect exposure. This isn’t immediately intuitive; the reason is because if you get it very, very wrong, you’ll find that after correction, the dominant colors in the shot will shift, and the sensor may not have gained up enough at the extreme ends (red or blue) resulting in underexposure – most likely. You can to some extent recover this in post, but the bigger problem is that you’re going to land up with a very noisy image – the blue channel is generally holds the most noise for most cameras as it is the least sensitive due to the laws of optics, photon energy and filtration…but I won’t go into that here; complex quantum mechanical formulae are beyond the ability of my blogging software to input and display. :)

_7035823 copy

Bottom line: shoot raw, and get in the right ballpark. Small adjustment are fine, and you can never get it 100% right all the time with a manual balance because ambient light is always changing. AWB works reasonably well on most cameras these days, but you have to watch out for the very warm light sources. I was told by several people in the camera industry that it was a conscious choice to leave the yellow/red components in the tungsten AWB because people expect the light to be warm (back to perception) – and having pure whites just looked odd to most consumers. I can attest to that as a lot of my students have asked me why the color is so blue when shooting indoors! Although I can’t say whether it’s a visual expectation on the part off the photographer, or whether inaccurate white balance is something they’ve come to expect because it was inadvertently dictated by the industry.

I’ve been playing with a handy little tool recently called a WhiBal. Basically, it’s a very, very accurate neutral gray card. I’ve found there are two ways to use it – one, take a shot under AWB with the card in the frame, and use that as your reference frame; eyedropper tool WB from the card in ACR, then sync white balance between the remainder of your files. Note that these two methods only work when your lighting is consistent from frame to frame, i.e. under studio conditions. The other option is shoot the card under the lighting conditions you’re going to use to set the preset in camera; I find this works better because all of your frames are automatically synced from the shoot. And if you’re using the same setup – as I do for watches – I can basically do it once and just leave one of my manual presets to match my flash and diffuser combo.

_7035796 copy
If any of you have shot purple flowers, you’ll know they’re notorious for shifting towards blue: that’s because of the UV reflectance. Flowers have UV and IR reflective pigments to signal to other animals – in this case pollinating insects and birds – that can see UV and IR.
Nepal. Nikon D700, 24/1.4 G

Next, make the tweaks – in your RAW converter, (I use ACR 6) perfect your white balance. Use the eyedropper tool on various gray areas in the scene until, it looks close to what you remember. (This is another reason why I like to process as close to immediately as possible: you might forget what the originals scene looked like, or any processing ideas you might have had at the time). Don’t worry if the eyedropper tool doesn’t get it right; you can shift the color temperature and hue sliders a little until you do.

_7025478 copy
This blue is one of the most difficult colors to get right. What makes it so appealing as a car color – the fact that it changes a lot under different lighting conditions – also makes it a royal pain to photograph and represent accurately. The honest truth is that I have no idea what RGB value this actually is, because it’s both reflective and in many spectra. Nikon D700, 28-300VR.

Open your file, make whatever contrast adjustments you need to – curves/ levels – then only use the Hue/Saturation tool to adjust the individual channels. Using curves inevitably shifts the saturation and hue slightly – there’s no way out of that – so you’ll need to bring back the individual channels. For instance, if it’s predominantly red and you used a curve that darkened the image, you’ll have to compensate for that by reducing saturation and increasing lightness slightly in the Hue/Saturation tool. There is no exact science to this – it’s all about experience, perception, and having the most accurate monitor you can find.

_7021997 copy
Remember what I was saying before about shellfish and birds? Nikon D700, AFS 60/2.8 G Micro

Each camera has a different filter pack and spectral response. Even though manufacturers try to keep the color output consistent from model to model, there will be differences. The D3100, for instance, has a crappy color gamut that I was never happy with – much like the NEX-5 – however, the D700, D5100 and D7000 are all pretty similar. The D800 is close, but even more accurate and with a wider supported tonal range out of the box. The M8 with UVIR filter, M9 without and S2 are almost identical. Since I use a whole bunch of cameras – at the last check, Leica, Nikon, Olympus and Ricoh – I’ve created individual color profiles for each camera in ACR and saved them as camera defaults. The look I like is somewhere between the tonal richness of Leica and the warmth of Olympus – perhaps Olympus + Zeiss glass describes it best. Oh, and different lenses have different spectral transmission characteristics too, just to make life more interesting. Your personal preferences will almost certainly be different because each individual perceives color differently. But I suggest that if you have the time, this is a worthwhile exercise.

_7022462 copy

One important final note: all of this is in vain if your final output use is extremely limited gamut or highly compressed (*cough*FACEBOOK*cough*) – all of the additional tonal information you tried to save is going to be lost and compressed to hell. Some browsers (Safari) and photo sharing sites (Flickr) are better than others because they are color profile aware and don’t compress images, but the issue then becomes monitor accuracy. So unless you know the final output method and have some control over it, it’s very tricky to ensure that everybody is seeing the same thing. And printing is a whole separate blog on its own…MT

Zone focusing and shooting hyperfocal

Hyperfocal shooting is a subset of zone focusing. Both are very, very useful tools in the arsenal of a photojournalist or street photographer; especially so if you’re using a manual focus lens, or one with a meaningful depth of field scale engraved on it. It means that if you know what distance your subject has to be at to fill your frame correctly, you can set that and just shoot straight away when you bring the camera to your eye – a very fast way of working. It’s what I usually do when I have enough light and a wide lens on my Leica.

Let’s start with zone focusing. It’s simple if your lens has a depth of field scale:
1. Pick an aperture
2. Find the depth of field scale markings corresponding to that aperture.
They’re on the bit of the lens that doesn’t rotate.
3. There are two of them. Everything between those two marks will be inn acceptable focus. Why the hesitation around ‘acceptable’? Because sharp-at-the-100%-pixel-level defines acceptable focus, and that will vary from camera to camera – the higher your pixel density, the narrower the acceptable focus margin will be. You’ll have to experiment for your camera and find out how much (if anything) to compensate by – for some cameras, you might find you have to as much as halve the width of the gap between the two markings.

_D90_DSC7238bw copy
Leica 21/1.4 Summilux-M ASPH.

Example: in the image below, the lens is focused just after 1.5m. This means the sharpest point will be at 1.5m, but if we set f2.8, objects from 1.2m to a bit over 2m will be in focus. Selecting f5.6 expands this further to 1m to 5m.

A good rule of thumb is 1/3-2/3: one third of your DOF will be in front of the focus distance, and 2/3rds behind.

Simple, right? There are a few more things to know.
1. It works best for wide-angle lenses, because they have more DOF for a given aperture. (You could zone focus with a telephoto, but you’d need a silly small aperture and probably run out of light).
2. It works best during daytime, because you’ll have enough light to stop down a bit (and thus increase your margin for error).
3. It works best if you have some practice estimating distances, because you can adjust on the fly without having to bring the camera to your eye.
4. It works best with smaller sensor cameras, because again there’s more DOF for a given angle of view (focal length equivalent) and aperture – for instance, the Ricoh GR-Digital III has a ‘snap’ mode that sets focus to certain distance; at f2.8 and 1.5m, almost everything will be in focus from 0.75cm onwards or so.
5. You can’t do it easily with modern AF lenses – those which do have DOF scales usually only give f11 and f22, which are heavily restricted by the amount of light you’ve got to work with; then the distance scale itself is short and probably not very precise, with few distances marked; lastly, there isn’t enough precision in the focusing ring. You could do it by using the AF system to focus on a distance, switch to MF, and set your aperture – but you’d have to memorize your DOF tables, which is never easy or fun.
6. Some compacts are better than others for this than others; the best kind have manual focus with a DOF indicator bar and scale – the Leica X1 and Ricoh GR-Digital series come to mind.

Let’s move on to hyper focal. The hyper focal distance is the setting beyond which everything is in focus to infinity at a given aperture. Even super-shallow DOF lenses like the Noctilux 0.95 have a hyper focal distance – but it’s probably 50m or something at f0.95. Once again, the wider the lens, the nearer the hyper focal distance will be for a given aperture. With lenses in the 28mm range, you can work at a reasonable aperture of f8 or so and have hyper focal distance at about 3m on a full frame sensor, which is great for capturing spontaneous moments in photojournalism or street photography.

There are several very useful calculators online, such as DOF Master – playing around with this will give you a good idea of which of your camera/ lens combinations is best suited to zone focusing. I personally do it with my Leica M9-P, and sometimes with the Ricoh GR-Digital; but never with the DSLRs because AF is very nearly as fast, especially on the D700. Also, beware lenses like the Olympus ZD 12/2 for micro four thirds – it might look like it has distance and DOF scales, but the focusing ring is electronically coupled, and lacks the resolution to make it truly useful. MT

Workflow

I get two questions regularly:

1. “What camera should I buy, or should I buy X or Y?”
2. “I have the same equipment as you. How do you make your images look the way they do? Why can’t I do it?”

I’m not going to address the first question here. As for the second question, there are two answers and one fundamental underlying question: assuming the problem isn’t with your composition, what is it about your workflow that creates that very visible difference in the final image?

Workflow is very important to professionals, because if you’ve got a very high image throughput, then you can take on more work, deliver better quality images to your clients, and at the end of the day, make more money. So it’s in our interests to be as efficient as possible, without sacrificing quality. Good workflow should have the absolute minimum number of steps, be fast and easy to execute, automated to the greatest extent possible (but recognizing that individual images are like children: you have to treat each one differently) and most importantly, be camera independent. The latter requirement is so that you are free to use the best tool for the job without worrying about what to do with the files later. There’s no getting around the fact that different cameras and lenses require different amounts of editing or correction to achieve the desired results; it’s just something that has to be built into your process.

A common misconception is that workflow just covers the post-shoot editing process: it doesn’t. Workflow affects the entire way you execute an assignment, from preparation to final image delivery. What follows is a high level overview of the way I work, and some of the key steps.

1. Prep
- Make a list of equipment you’re going to need.
- Charge batteries, and bring 2x the number you think you’ll need – s*** happens.
- Ensure you have spares: cards, batteries, flashes, bodies, RF calibration spanners…
- Unless you’re shooting a run-and-gun stealth photojournalist assignment, or are going to be carrying your equipment for long periods of time, take everything you think you might need. Better to have it and not use it rather than miss a shot for want of a lens.
- Pack with plenty of time to spare, in case you find you’re missing something or can’t decide which configuration to use – at least you’ve got time to think it over or go out and buy anything critical that’s missing.

2. Shoot
- Turn up early so you can set up (if required) and be relaxed. Nervousness means jumpy hands which means blurred images.
- I always shoot RAW, for maximum latitude later when processing.
- Write-protect your keepers in camera to prevent accidental deletion.
- Shoot bursts where possible, both to get duplicates (insurance) and a choice of material to work with later.

3. First edit
- Delete the ‘obvious fail’ shots in camera when you have downtime – but ONLY when you have downtime. Missing a shot because you were staring at the back of your camera is an amateur’s mistake. I’ll probably dump about 50% of the images at this point.

4. Post-shoot
- Unpack
- Clean equipment – lenses, filters, eyepieces, LCDs etc.
- Recharge any depleted batteries
- Put everything back where it came from, so you can find it again next time.

5. Dump cards
- I will dump all cards to my primary processing machine at this point, and leave the cards unformatted back in the camera – just in case a file gets corrupted or I need the original, I know it’s still there.

6. Backup
- I use a Mac. At this point, I’ll run a time machine backup on my primary processing machine.

7. Second edit
- Delete the images that don’t really work at larger sizes – see my previous article here on editing. I use Adobe Bridge to delete and rate images. Another 50% of the images will go.

8. RAW conversion
- Depending on your machine, figure out how many RAW files you can open before it starts to slow down (use the ‘efficiency’ display in Photoshop; it’s in the bottom left of your image window. 100% means that everything is being loaded to RAM, which is the fastest way of editing). I can open about 15 12MP files in 16 bit before things start to slow down. This means I’ll probably load 20-30, because I also delete some at this point.
- Load bunch of files (20-30) into Camera Raw.
- Make primary exposure adjustments; I will adjust white balance, exposure, shadow/ highlight recovery sliders, vignetting.
- I only crop to aspect ratios that are non-native for my camera. If I’m using a multi-aspect ratio camera like the Leica D-Lux 5, I won’t crop at all.
- I have created a color profile for each camera I use so that I can get consistent color and the same look out of any camera I use, this is applied to the raw file in ACR.
- And same for the tonal response curve.
- Open the files in Photoshop (I’m using CS5.5 Extended now) at maximum quality: 16bit, full resolution.
- B&W conversion: depending on what final look I want, there are many options: gradient map, desaturate, channel mixer…to be the subject of a future article.
- Make curve adjustments – sometimes up to four or five times.
- Any retouching is done at this point – e.g. dust removal for product shots, or color enhancement using brushes and masks. I use a Wacom Intuos4 6×9″ tablet for this, nothing else so far gives me enough fine control.
- Local dodge and burn where applicable.
- Finally, sharpening: do this last, so you don’t land up increasing image noise/ grain. Must be done after curves.
- Convert to 8 bit and desired color space.
- Save final file. I generally use a maximum quality JPEG unless the client demands otherwise; you really can’t tell the difference unless you’re going to do future manipulation on it. (Revisiting old files will be the subject of another future article).
- Optional: do an incremental backup again, if it’s a big conversion job you can’t finish at one sitting, or if each file is time consuming and will take a lot of effort to duplicate.

9. Final edit
- Go through the set again. Keep only the unique, essential images. By the time I’m done, I keep only 1-5% of the initial shoot volume.

10. Portfolio selection
- I keep a portfolio of images for the subjects I commonly shoot; this gets updated after every shoot, especially if I feel there are images that should be added. It’s my aim to have at least one image to add to the portfolio (and replace an old one) from each assignment; this way, I force myself to continually improve.

11. Backup and format
- Dual duplicate sets of images with all raw files to external hard drives, one of which is kept offsite
- Keep finished files only on main processing machine
- Final backup: time machine of main processing machine
- Only now will I format cards. Where possible, I keep at least two copies of the original files – just in case something goes wrong. It’s happened to me in the past, and I’ve been very, very grateful that I did remember to backup. I’ve been doing it religiously ever since, and highly recommend you do the same.

A note on filing: I store images in hierarchal folders by Subject>Event/date>Subset. This allows me to find things easily. I have a separate folder for work on assignment, which is named with something sensible and a date. I don’t like database-based programs for image management like Aperture, because it’s very difficult and unwieldy to manage if you have a lot of images.

12. Delivery
- Send off the images to clients; either over the web, or via DVD.

Now, repeat! MT

The process of editing

Let me clarify: by editing, I mean the process of selecting which images to keep, which make the final cut, and which aren’t wroth bothering with. I’ll generally do three edits: one almost immediately after shooting, in-camera; one when I get home and dump the cards/ start converting raw files; and the final cut after I’m done making finished files, but before I archive or deliver complete sets to clients.

As an example, let’s take the contact sheet I used in an earlier article on how to use contact sheets. For the purposes of this exercise, assume that this set is one that came fresh out of the camera (in reality, it’s already been through the complete selection process, and no, I don’t shoot jpeg unless I have no other choice.)

First cut (in camera)
I’ll delete images which are:
- Clearly out of focus
- Incorrectly exposed
- Compositional failures/ experiments that didn’t work
- Clearly meaningless/ no obvious subject
I’ll leave duplicates or near-duplicates of good shots; you can’t judge fine detail or critical focus off the back of a camera screen.

For the example, I’ve already taken out the first cut in camera, so let’s move on.

Second cut (before raw conversion)
I’ll delete images which are:
- Not critically sharp
- Didn’t work as well as expected when viewed at a reasonable size (full screen, usually)
- Compositionally weaker than the rest of the set
At this point, I also pick the best image if there are a series of duplicates or near-duplicates. (Duplication is something I do where possible to give me the best possible selection of raw material to work with.)

Final cut (before delivery)
- Eliminate similar images, so that what you’re left with is a series of individually very strong photos, each with a clearly different character
- Chose only the best X images, where X is your delivery target/ agreement


Final cut. Notice how each image in the final set is distinctly different from the other, yet I haven’t ‘lost’ any critical shots, and manage to capture the essence of the movement of the watch.

I’ll leave you with one final thought: the mark of a truly good photographer is not how many good shots he produces, but rather how many good shots the audience remembers: if you only show good shots, nobody is going to think you’re capable of producing a dud. Furthermore, if you aren’t your own harshest critic, your skill level is never going to improve. This is why editing is so crucial to the entire photographic process; I force myself to keep only the best 1-2% of everything I shoot. MT

Contact sheets, and how to use them

This article is a lead on from my earlier review of the Magnum Contact Sheets book.

Contact sheets are a tool that date from the days of film: basically, the developed negatives are laid out directly on top of photographic printing paper, exposed for the appropriate duration, and fixed. They aren’t ‘proper’ prints per se, but a provide the photographer and editor a quick way of looking at all of the images in a sequence at once.


A printed (or from negatives) contact sheet would probably look something like this.

The photographer would then mark out his first and second cut images, followed by the verification from the editor; the chosen images would then be printed properly from the original negatives, with any tweaks required (such as dodging and burning, increasing exposure, changing print density etc.) With the analog photography process, that marked the end of the line for the photographer unless they also did their own printing – which was rare.

Interestingly, contact sheets were considered something of a luxury item for photographers because of the cost of producing them – especially when there were a lot of rolls of film to go through – most photographers just used a loupe and light table, or if desperate, held the negatives up to a window.

Contact sheets still remain a useful tool, not just because they allow you to see all images at once and judge their relative merits, but also because they force you to look at the distilled essence of an image: if a shot makes a compelling thumbnail, it’s generally also quite powerful at larger sizes. However, the reverse isn’t true: some shots need to be printed large to work well, landscapes, for instance. With images like this, contact sheets aren’t necessarily the best tool (unless you’re shooting medium format, or have larger thumbnails to work with).

Not shooting film? Don’t worry. We can still do the same thing today in the digital world. Photoshop itself has an automated tool (File>Automate>Contact Sheet) to create contact sheets of images; these are useful to print or send to clients. Alternatively, programs such as Bridge and Lightroom effectively let you create digital contact sheets which you can interact with on the fly:

What these programs let you do is a) see everything at once; b) see only the ones you wanted; c) use a magnifying loupe to check sharpness on a particular image or several images to compare; d) here’s the important bit: rate images. With Bridge and LR, Command-[number] lets you tag a star rating from 1-5; later on, you can filter by images rated at a certain level or above. And it works for raw files too, so long as the camera is supported by Adobe Camera Raw.

My current process is to keep all images from a shoot (except the obvious duds or unsuccessful experiments, which I bin in camera) and then conduct a first pass edit using the contact sheet view as soon as they’re in the computer – I’ll rate my images 3, 4 and 5*; 3* are kept because they’re useful for stock or remembering a particular event; 4* are good images and deliverable to clients; 5* are portfolio grade, best-of. The rest aren’t worth keeping and get binned. I’ll work on the 5* images first, and go down the quality ladder from there. That way, my best images are immediately ready to go, and if I don’t get a chance to make a final file (analogous to printing) of the 3*s, I can always come back later.

As photographers, we often fall into the trap of either being overcritical (bin all) or sentimental (bin none) – neither approach is good. For personal work, using contact sheets helps you to edit and see what worked and what didn’t (and by combination, what ideas might work in future if combined). On assignment, it lets you see the relative merits of each image and ensure that you’re only turning in the very best. Contact sheets are a powerful tool to help you achieve this – and the cost of printing is no longer really an excuse. MT
