Photoessay: Design goals

_8B40588 copy

Regular readers probably know that I have more than a passing interest in all things horological; firstly as an aspiring collector, then a photographer (this is what motivated me to begin, to be the story of another article), then a low-budget collector, and fortunately, somebody who has access to the industry through client relationships and options that might not be available elsewhere. Eventually, I realised that the temptation to design my own was far too strong; finding the right collaborator proved less easy, but I eventually realised that dream (more detailed story here). It is, unfortunately, both an addictive and frustrating process: inevitably, once you’ve lived with any design for any length of time, you start to appreciate what works and get frustrated by what doesn’t. It’s even more frustrating when you have ideas you might want to try, and know that you can (somewhat) easily execute them. Some CAD and some sitting time later, the design has matured and you are making some phone calls. The trick is not to overdesign: it is easy to make something that’s too fussy and just doesn’t work.

On Assignment photoessay and challenge: Making a $200 watch look the business

_8052118 copy

Today’s photoessay-on-assignment-report hybrid comes courtesy of a regular client who both makes their own and OEM watches for other companies. They’re not a big name – you’ve probably never seen the brand outside Asia, if at all – and they’re certainly not competing at the high end, but they do have mass-market volume; it’s a very different sort of assignment to the kind I normally undertake in Switzerland. It doesn’t require much skill to make an exceptional watch made with no consideration for price look exceptional; the challenge there is making it look extraordinary – otherwise your photography has not added any value or even done the object justice. My job here is very different: how does one make a $200-retail watch look like a $2,000++ one?

On Assignment: back to the hospital

_8020693 copy

This hospital has turned into one of my regular clients – I went back for another couple of shoots. Incrementally, we’re working our way through the departments and refreshing their image banks. I’m also hoping to shoot live surgery at some point in the future, but no idea if that’s going to be cleared by their board or not – there are so many things that might be unacceptable both from a hygiene point of view – you can’t autoclave a camera – as well as privacy etc. Still, it’ll be an interesting experience. At least light shouldn’t be a problem, given those fantastically bright operating theatre fixtures. (Side fact: one of the reasons why I didn’t go to med school was because I couldn’t stand the sight of blood. But oddly enough, operating a camera makes me focus on shooting and completely ignore everything else – the resultant being that I’m happy to shoot in places which I’d never even think about visiting ordinarily.)

_8019369 copy

But, I digress. With this post, I wanted to talk a bit about lighting on location. Hospital lighting in the wards tends to be uniform, flat and uninteresting: fluorescent tubes, more fluorescent tubes, and yet more…you get the picture. If you’re lucky, they might even be color matched. Fortunately, to keep patients feeling comfortable with the ambience, most of the time they’re at least daylight-balanced tubes (this is important, because it means you don’t have to gel your flashes to balance out ambient).

_8019694 copy

A typical scene involves some equipment, a doctor/ technician, and a patient. And the interaction is what we’re trying to capture, along with some sense of context, along with a bit of ‘ooh, look at the fancy machine’. This means that lighting is a bit of a challenge because you’ve got to have a nice diffuse source to make the humans look good, as well as something a bit punchier and more directional to give the machines some depth and dimensionality. On top of all of this, there often isn’t that much room in which to set things up, and ceilings aren’t that high. Oh, and it’s also a working hospital, so time is very much of the essence.

_8020533-43 copy
Composite shot – the glass was far too reflective and dark (it was a sleep lab, after all) so I had to shoot one of the monitoring post, another one of the computer screen, and a third inside the sleep lab itself from approximately the same angle of view of the operator and line of sight.

The setup I go with is a pair of speedlights on stands with umbrellas; either shoot-through (for the primary light on the humans) or bounced reflector (for the machines). Sometimes I’ll add a third speedlight as a catchlight or to brighten up the background a bit. For the most part, Nikon’s CLS/ iTTL system works pretty well, though the background speedlights sometimes don’t trigger due to being out of the line of sight. But a little tweak to position and usually all is well again. I was considering radio triggers, but then I was told that they weren’t allowed in the hospital as they might interfere with critical equipment such as pacemakers and life support machines (!) – probably best not tried, then.

Workshop report: 28 Sep Making Light in Kuala Lumpur

_8021743 copy
Our model for the day, Aliza Kim. Nikon D800E, 85/1.8 G

Although unfortunately Kristian Dowling couldn’t co-present in the end due to food poisoning, the show must go on, and it did: an intimate and dedicated class of participants joined me for a different look at making light in the studio. We started with a deconstruction and minor reprogramming of preconceptions: the use of a studio is about total control for all aspects of the image, not just lighting; why compromise when you are in a repeatable, 100% controllable environment?

And setup shot for the above: only the 4×6″ softbox was in play.

The morning was spent examining firstly the basics of the principles of composition, color theory and psychology, the importance of perfect color and how to achieve it, and finally, deconstructing lighting under several increasingly complex scenarios – one light, two lights, reflectors, multiple lights, balancing with ambient…I’m proud to say that the students did an increasingly good job of figuring out what the light setups used were, even if I did throw them a few curve balls 🙂 (There’s a reason why this post comes at the end of the last week’s focus on lighting articles!)

After lunch, we moved on to replicating most of these setups, starting simple with one large softbox…

_8021661 copy

…a variety of poses, practice with timing, framing and anticipating where to leave space when the model moved…

_8021674bw copy

…including setups involving two lights:

_RX100_DSC1613b copy

…strong backlight (that’s the 4×6 softbox serving as backdrop in the left edge of the frame)…

…and the use of a single-beauty light from a more oblique angle to create interesting silhouettes:

_8021749 copy

One more costume change later, and I demonstrated the versatility of speedlights for location work and ease of creating completely different effects by mixing diffuse and harsh light. Here, we used a three-light setup to create a very edgy, moody, feel; later on adding a cinematic and emotional element by varying the color tone of the final shot, or omitting it completely. The speedlights were set to manual output, triggered and controlled via iTTL for the Nikon shooters, and switched over to SU4 slave mode for the Canon shooters (and lone Sony RX100, the B-roll camera of yours truly.)

We finished up the day with a quick Photoshop postprocessing demonstration to clean up a few files for print by the studio’s resident print master, Wesley Wong of Giclee Art – thus completing the imaging chain, and showing just how much further you can take your images when you’re in control of all of the elements. Even at 13×19″, the RX100 images were virtually indistinguishable from the D800E – we would have to go even further, probably to 25×40″ or so, before a significant difference would be discernable. Score one for the argument for sufficiency! I’m pleased to report that everybody had a great time and learned a lot (or at least were polite enough not to say otherwise 🙂 – in the words of one participant, “I think my head just exploded.”

Our group and model.

I’d like to conclude with a quick note on equipment: we were using Profoto Pro heads, a D4 pack, one beauty dish with and without 25deg grid, 4×6′ and 1×4′ softboxes, three Nikon SB900s, umbrellas and a whole array of clamps and stands for lighting; the model images in this post were shot by me (except for the one ‘Charlie’s Angels’ shot where noted) using a Nikon D800E, Nikon AFS 85/1.8 G, Zeiss ZF.2 2/50 and 2/100 Makro-Planars. B-roll, documentary, and one of the model images was shot using a Sony RX100, except of course the images of me which were shot by the students as the camera made its rounds to be fondled…

I’d like to say a big thank you to the participants, and Shriro-Malaysia/ Profoto for the use of the studio and lighting equipment. Stay tuned for more upcoming workshops!

Deconstructing light, part four: continuous sources

The final part in this introduction to lighting mini-series is a look at when continuous light sources can be useful, and how to best deploy them.

I use continuous lighting primarily for food photography – specifically, large, high-CRI LED panels – because the low temperature of the source doesn’t interfere with the subject. (Try blasting sashimi with flash repeatedly, and you’ll soon see just how fast delicate fish can cook.) However, it’s also useful in other situations – obviously, to give clients an idea of what the end result will look like; for videography, when flashes obviously aren’t feasible, and less obviously, when you’re working in a dark environment and actually need a reasonably accurate representation of what the light will look like in order to compose and focus.

The rules for using continuous lights are pretty much the same, but with a few limitations:
1. Color temperature usually isn’t variable, and for large sources, you might not be able to find gels big enough – so you will probably have to go with almost 100% artificial light in your exposure. Note that you can also find continuous tungsten lights, but these run very hot and have a very low color temperature, which can lead to problems with blues.
2. LED panels aren’t that bright, so you will need to work with a tripod, and again, watch ambient light – it will creep in because the exposure times will necessarily be longer than for flash photography.
3. Subject motion – another consequence of longer exposures, especially with human subjects.
4. Heat. If you’re using tungsten light, be careful with things accidentally coming in contact with the bulbs or heads and catching fire or burning. That includes your skin.
5. Power. You’ll need to be plugged into mains or large batteries for lights of any consequential power. Ensure you take this into account when planning for a shoot – extension cables and power strips are your friend!

Let’s look at some examples, shall we?

_DL5T_L1000740 copy
The end of sorbet. Leica D-Lux 5

Single small LED panel to the top; note the hot spot on the spoon. The problem with using panels is that they’re difficult diffuse without a significant loss in power; the only way to make it work is either live with the hot spots (not a major problem for food) or get bigger panels (very expensive). I wanted my panels to be versatile, so I’m now using 45x45cm models.

_MM1_L9995676bw copy
Test shot from the M-Monochrom review. Leica M-Monochrom, 50/2 APO

One large LED panel off to the right; since it was a test shot, I didn’t bother to clear the wire from the foreground…with human subjects, LED panels enable faster, more comfortable working as you don’t have to make as many trial and error adjustments with the flash, and it’s simply not as hot.

_DL5T_L1000648 copy
Bread. Leica D-Lux 5

Part of a series from a food photography class I ran for Leica earlier in the year. I had two small LED panels for this, spread out around the top of the image and on even power; they provided definition and shadow. Image was shot top-down, obviously.

_DL5T_L1000646 copy
Foie gras. Leica D-Lux 5

Two LED panels; one top left, one top right. Both slightly above the subject to highlight that moisty, oily sheen on the seared foie gras. LED panels are quite directional but yet with short throw; this means they’ve got to be fairly close to your subject, and you’ll need more than one to fill in the shadows.

_DL5T_L1000702 copy
Leica S2, using the D-Lux 5

This is an example of what you can do when you have 40 LED panels at your disposal – I demonstrated product photography using the mini-panels to create a ring of light around the subject, with some actually providing light on the subject, and some just there to provide background texture.

_DL5T_L1000981 copy
Sushi platter. Leica D-Lux 5

One medium panel from the top took care of lighting here – getting the height and angle right is the critical part, so that the subject is evenly lit but yet has definition to preserve the shape and texture of the fish. Panels were about 30cm above the subject in this case.

_5003422 copy
Rice cones. Olympus OM-D

I used two panels here – one on full power from the right side, slightly elevated relative to the plane of the plate, and slightly behind; the other was to the left and running 1/8th power to provide fill and keep the food looking fresh and ‘bright’ rather than shadowy and ‘heavy’. Lighting is all about psychology and creating the desired mood in the viewer…

Deconstructing light, part three: balancing ambient

One of the neat things you can do when you’re controlling the light is highlighting your subject, but preserving the ambient atmosphere. Today’s post focuses on how to do that.

Ambient light is your friend: it helps you to fill in the background with pre-lit object, providing compositional context; but more importantly, you can use it to preserve the atmosphere of the scene, which can be difficult to recreate if you’re using 100% flash or strobe only. All of the previous control points for single and multiple lights apply, of course. The two major challenges with balancing ambient are exposure and color. I’ll deal with exposure first.

There’s no fixed rule for this, but the more ambient you want to preserve, the closer your exposure must be to ambient exposure; the best way to do this is by shooting in manual mode and balancing out your shutter speed and aperture until you’re around one stop underexposed; I wouldn’t do anything more than three stops of difference (unless you have very bright ambient point sources) because very little, if any, ambient sources will remain. You’ve got three parameters to play with here – shutter speed, aperture and ISO. Shutter speed should fall somewhere between your max sync speed and around 1/30s if you’re dealing with people; higher if there are moving objects, lower if static. Aperture should allow you to hold in focus whatever you need to. ISO is the remaining balancing factor once you have set the other two – try and keep this low to maintain image quality, however. I generally don’t go higher than 800. Note that flash power should be the last thing that’s altered (and done by the camera’s meter to balance out the required exposure) – this is because you are firstly setting your exposure based on ambient, then filling the primary subject with the precise amount of flash required for a proper exposure.

Color is actually simpler: if it’s daylight, or close to it, there’s no need to gel your flashes, because they operate at fairly close to daylight Kelvin temperatures. If it’s tungsten or fluorescent, you’ll need to use the correct gels over the front of the flash so they provide the same temperature color source as the ambient lighting; you’ll also then have to set the white balance in-camera to match ambient. Note that you don’t always have to match the flashes to ambient; sometimes having a bit of temperature difference isn’t a bad thing, as it can help to highlight the subject. Just don’t make the difference too glaringly obvious.

Let’s move on to the examples.

Omega Speedmaster 9300. Nikon D800E

One of the more common situations I face where I have to balance flash and ambient are lume shots of watches – you need a very long exposure to capture the glow luminous material; often 30s at f16 ISO 100, or longer. However, a luminous dial pattern on its own isn’t very interesting, so I usually supplement this with some ambient. You could do this two ways – composite a regular (but underexposed by several stops) shot in, or just add a manual flash kicker to define the case. Here, I used 1/16th power from top left through the diffuser box.

_7061864 copy
Sandwich. Nikon D700

The background glow is the restaurant decor; I had flashes reflecting off umbrellas left and right to illuminate the sandwich. Exposure was balanced out to expose two stops under ambient for the restaurant, with a longer exposure time and base ISO (sandwiches don’t do much moving).

_D90_DSC7112 copy
Autumn texture. Nikon D90

One flash from the left, not diffused to provide a bit of harsh light to add texture and definition to the subject; exposure 1/2 stop under ambient. I wanted to fill the shadows and create some cross-lighting effects rather than make things soft and diffuse; a very flat angle for the flash position was used to accomplish this.

_8018601 copy
MRI room. Some of you might recognize this from a previous on assignment post. Nikon D800E

The objective of this shoot was to show the clean, high-tech environment of the hospital’s new MRI machine. The MRI and room itself had ambient lighting on both the machine and ceiling; if we shot with this alone, firstly our models wouldn’t have been able to keep still for long enough, and secondly, the ambient light was far too cool with a large difference in color temperature to the machine. Hence, flashes were used to illuminate the room and models – one in a reflective umbrella to the top right corner of the room; I needed throw and definition for the whites. The second one was placed on top of the rear casing of the MRI to fill the back of the room.

_8018569 copy
Mammogram. Nikon D800E

Here, the client wanted to convey a warm, friendly feeling to the room; nothing says this better than warm lighting. The color temperature of the flashes were shifted with gels; the primary source source was a flash reflected off an umbrella behind and above the machine; a secondary flash was bounced off the wall behind me (and to the right of the patient) to provide fill at 1.5 stops under the main flash.

_7065341 copy
Sony RX100 product shot. Nikon D700

The final example is one of those deceptively complex shots: one flash from top right was fired through the diffuser to light the camera body and background, but the exposure was altered until it balanced out that of the screen. If I’d just used the native sync speed of 1/250s and stopped down, the screen would black out because it isn’t that bright.

Come back again tomorrow for the final part in this series! MT

Deconstructing light, part two: multiple sources

Part two deals with multiple sources: how and where do you use them? What is the one key rule to remember?

Although you can do a lot with a single flash, there’s even more that can be done with two or more. For starters, you can fill in shadows; or if you want to get more adventurous, you can mix both hard and soft light (direct and diffused) for better definition, or more accurate replication of found light sources. (There’s one particular shot I’m rather fond of that I call ‘the Hollywood’, which I’ll go into later).

There’s one critical thing to remember when using multiple sources, though: there must always be a primary source. If you don’t have one, then you won’t have any subject definition – opposing sources will fill in the shadows, and shadows are what defines the shape of an object.

The same parameters you can control with a single source apply to multiple sources, of course. The more sources you have, the more complicated things get. It’s useful to decompose your thinking thusly:
1. Primary source, on main subject
2. Secondary source, on main subject – definition (rim light, not diffused) or fill (diffused, or reflected)?
3. Other sources, for background objects or secondary subject – take steps 1 and 2 and repeat.

I’m sure you can now see why Joe McNally needs several trunks full of speedlights. I’m not quite there yet, but I find that most of the time a two-light setup is sufficient; there are times where I’ll use three for watches, but I’ve yet to require four sources (except in situations where I need more power from one location, and have to add a second flash to turn the wick up a notch).

Let’s look at some examples.

_N207239 copy.jpg
Ferrari 250 GTO. Sadly, not a real one. Nikon D200

This one has two distinct sources, both flashes behind diffuser panels – one at left, and one at right. They’re actually slightly behind the subject to create a nice specular highlight that defines the curvature in the panels; if I’d put the sources at right angles, you’d have very flat illumination and not much of a feel for the 3-D shape of the car.

_3002397 copy.jpg
Nikon 14-24. Nikon D3

Some objects betray their lighting secrets very clearly – reflective hemispheres are perhaps the worst culprits. For something like this, the best thing to do is keep the light source simple; in this case, two softboxes from the left and right. Power was equal; if not, you wouldn’t get the nice multi-colored reflections off the coatings on the lens. Note that the softboxes were actually pretty close to the subject; the hemispherical shape makes them appear further away.

_7052948 copy
Lange Datograph. Nikon D700

Through a trick of optical projection, the watch actually appears floating in mid-air and truncated, even though it’s resting securely on the surface behind. Note that this was shot with the lens and watch resting on a flat surface, but lit as though vertical. The primary source was through a diffuser, aimed at the watch and shielded from lighting the lens in front; a secondary source, at reduced power, lit the nameplate of the lens; finally, a third source – again at reduced power – lit the background. A simple-looking shot, but a bugger to light.

_N215925bw copy.jpg
Panerai Arktos. Nikon D200

Sometimes you want hard definition; in such cases, a concentrated, direct source is the best way to go, without diffusion. Here, I used one flash from the top, and one from the bottom to provide fill. Both were positioned at a low angle to avoid flat-looking interference at the point of the subject closest to the camera, with a small baffle on one side of the flash preventing light spillage.

_7060545 copy
Steak. Nikon D700

This example is an instance of when two light sources look like one. A flash with reflective umbrella was used from the top right; you actually need to see a bit of harsh reflection off the oil on the steak to know it’s a juicy steak, making a reflective umbrella ideal. However, you still need to soften out the edges a bit, which is where the very low power secondary source comes in; if it’s too diffuse, you lose the defining effect of the first source, so there’s another flash reflecting off an umbrella from the left, too.

_3009669bw copy
The Hollywood. Nikon D3

There are actually four flashes in play here: two at the back to provide the spotlight effect and backlit definition on the subject’s hair; one from the right in a softbox as the primary source, and a fourth on the D3 to serve as remote commander.

_7056862 copy
Jaeger-LeCoultre Gyrotourbillon I. Nikon D700

Lighting at the macro scale is extremely tricky – partially because you don’t have a lot of working distance, and partially because your source has to be the right size: too large, and the light is too soft and lacks definition; too small, and you’re going to get harsh reflections and rough-looking surfaces. Here, I used one flash fairly close to the topmost diffuser, with a secondary one through the back diffuser to provide fill of the shadows – thanks to the handy aperture in the watch dial.

_7040287 copy
Seiko Fifty-five Fathoms. Nikon D700

We finish this section with a classic two-light: primary source upper back center, and secondary fill from the left to give the transparent domed objects – water and watch crystal – some definition. Not much power difference between the two flashes; the bigger difference was the location of the flashes. The back one was further away and with a wider spread than the left one; this created a larger source of almost equal brightness.

Deconstructing light, part one: one light

_7056032bw copy

Over the next few days, we’ll look at a few examples of lighting, and specifically, deconstructing it: what lights were positioned where, and what was the logic of doing so?

Today, I’m going to start with some relatively simple setups: they only use one light, with or without additional modifiers. Quite often, you don’t actually need much more than that. Single light setups tend to have very well defined shadows and highlights; chiaroscuro is the term that’s used to refer to an image that is predominantly described by it shadows and negative spaces. Classical painters were masters of this technique; they lit things in ways that are very difficult to replicate in real life – partially because of the size of their sources, and partially because they weren’t strictly limited by the laws of physics.

For simplicity, let us assume that you’re shooting at your camera’s highest sync speed, and that ambient light is not really a factor into the equation. Note that everything said here applies to both speedlights and studio strobes. I’m not going to discuss built in or on-camera flash, because it simply will not give you the results you need or offer the flexibility required. There are few variables in a one-light setup:

1. Output power
How bright do you want it? Usually, your lights will alter power based solely on your desired depth of field – which translates into aperture, which in turn translates into the amount of power required to provide a correct exposure. Note that the shutter speed only affects ambient light, not the power output of the flash. Flash duration is often 1/1000s or even much shorter. Most cameras will sync to 1/250s or thereabouts; this is the maximum duration of a full power flash. Those that sync at higher speeds require the flash to fire several times to cover the focal plane, as this is the highest speed at which the entire sensor area is exposed at the same time. (Anything faster, and the opening between shutter curtains is effectively a narrow moving slit.)

2. Distance
More distance requires a higher guide number to provide the same given illumination. Distance also affects the perceived size of your source – in general, providing the light isn’t a single point, the farther away you are, the brighter your source has to be for a given illumination level. For more diffuse light, you want your primary source to be further away.

3. Beam coverage/ angle
Most flashes and heads can have their beam angle changed – you want to match the beam angle to the focal length to produce the optimal balance frame coverage and power consumption; lighting more than you need to is a waste of power, but less than your angle of view will produce hot spots. Of course, you could always do this deliberately for a spotlight effect. Note that a wide beam close to the subject and diffuser will not look the same as a spot (telephoto setting on the flash) beam farther away with a big diffuser; the latter will produce far softer light.

4. Diffusion
The best example of diffusion is the difference between a clear, cloudless day and an overcast one: look at the difference in shadows. A cloudless day produces very harsh shadows and wide dynamic range with high brightness in the highlights; it’s a dynamic range nightmare (especially for outdoor wedding shooters, because of all that black and white involved). The opposite is true for cloudy days – note how soft and diffuse the light is. The clouds are effectively adding as a diffuser. For photographic/ flash purposes, you can use a diffuser – not a small clip-on thing that goes on your flash, but something larger like a softbox. The further away your source is from the diffuser, the softer the light is going to be. Control diffusion, and you effectively control the subject’s tonal differentiation.

5. Angle of incidence/ positioning
This seems obvious, but where you put your light and how you aim it can make a huge difference to the look of the image. In fact, it’s possible to leave the orientation of subject and camera fixed in one position, and just move your lights to create several completely different-looking images.

A quicks note on color and white balance: assuming all of your exposure comes from flash, just set your white balance to flash or daylight – most cameras will do this automatically. We do need to start worrying about mixed color temperatures, but only when balancing ambient and artificial light.

Let’s look at some examples.

Hair. Leica X1

Single speedlight in softbox; shot at 1/2000s sync speed – to freeze motion, I used a camera with a leaf shutter and high flash sync speed. The source was positioned at 45 degrees to the subject and camera to provide definition; it was not that far away from the subject to avoid too much diffusion – this way, you still get some highlight definition which helps give the subject shape.

Maitres du Temps Chapter 3 prototype dial. Nikon D800

Single speedlight behind diffuser panel to the top of the watch. The watch was inside a diffuser box to control reflections of surrounding objects off its polished surfaces. For images like this, the precise position of the flash relative to the diffuser and subject, as well as the beam angle, are very important – a small change in the position of the flash or beam angle changes the nature of the reflection significantly, as you will see demonstrated by the next image. For this image, the source was reasonably high up, far away, and with a wide beam angle to produce a soft reflection.

Lange Datograph. Nikon D700

This shot employed an almost identical setup to the previous one, except the flash was at a lower angle, much closer to the watch and with a tighter beam spread (longer zoom setting). Note how the reflection in this shot is very concentrated in one spot close to the top edge of the crystal, and is much ‘harder’ and more defined than in the previous shot.

_7058192 copy
Seasoning. Nikon D700

I used a flash in an reflective umbrella to the back left of the subject here; I wanted some diffusion but also some definition – too much diffusion and the pasta looks like a flat, matte amorphous blob. The source was partially behind the subject to provide a bit of backlight, which would define the grains of seasoning against the dark background of the person’s shirt. Note: there is such a thing as too much diffusion!

_7046623 copy
Girard-Perregaux F1-047. Nikon D700

Despite appearances, this shot actually employed direct flash with almost no diffusion. The watch itself is fairly matte, and the texture of the carbon-fiber dial is only apparent when struck with strongly directional light. I used a single flash to the right of the subject, almost touching the diffuser panel; this provided a minimal amount of softening of the edge of the flash source (so it wouldn’t appear as a hard point source in the minor reflections) but enough directionality to give the dial definition.

_7021997 copy
Prawns. Nikon D700

This example involves one flash again, but bounced off an umbrella fairly far away from the subject. Given that the room, tablecloth and surroundings were predominantly white, any light source used would reflect and provide some fill. This meant that the primary source had to be diffuse, yet directional – making an umbrella ideal.

Eugenie. Nikon D200

The final example involves a combination of light modifiers – a snoot and a diffuser box. The snoot was used to concentrate the light to the center of the diffuser; the diffuser was used to soften the skin of the subject. The net effect was a soft spot – imagine a source about the size of a large dinner plate, with intensity dropping off towards the edges. Thus, we get the best of both worlds – chiaroscuro definition, and gentle tonal rolloff in the shadows and highlights.

On Assignment: Time factors and big magnets

_8018601 copy
MRI machines are a lot thicker than they look on TV. Nikon D800E, Zeiss ZF.2 2.8/21 Distagon

I’ve shot for hospitals before, though not under these conditions. The day – well, night – before the shoot, I didn’t know I was going to be shooting the next day. Turns out that the hospital ordered a new MRI machine, at a cost of just RM13,000,000 – making it by far the most expensive object I’ve ever photographed. Here’s a bit of background on MRI machines: they’re so heavy that the room has to be purpose built to accommodate it, and the machine settled in then the rest of the place completed around the outside. (The control booth wasn’t operational or in place when I went there.) Apparently the magnet has to be cycled when it’s new to run in; during breaks in the cycling when the magnetic field strength dropped to zero was the only time we could go in to shoot it – they never fully turn the thing off. The upshot of all of this was that I had about half an hour to complete the shoot before they had to gas the MRI machine up with helium and start the cycling process again.

Inside the donut. Nikon D800E, Zeiss ZF.2 2.8/21 Distagon. Single SB900 with an umbrella outside to illuminate the patient and room. I don’t know why, but I kept thinking of Star Wars whilst I was inside here shooting.

There were about ten shots to complete inside the room – several of the room and machine itself, a few with a patient in it, and a couple with doctor-patient interaction. Needless to say, everything required lights to be brought in; not because ambient wasn’t bright enough, but because even, flat light is great for soothing patients but utterly crappy for providing definition on white objects. I used two SB900 speedlights for this shoot, triggered by the built in on my Nikon D800E. One was the main key light on a stand using an umbrella, and the other was placed to provide background fill. Whilst they work fine with line of sight, I do find myself wanting to hide them in ever more creative places; the inside of the MRI’s donut hole being one. I think I must be one of the few people to ever stick a flash inside an MRI machine. Perhaps I’ll pick up a set of Pocket Wizards at some point.

Half an hour and one haematoma on my finger later (I clipped it between the leg joins of my Gitzo while rushing to pack up) – good thing I was at a hospital – we were done. Possibly the most rushed shoot I’ve ever done, but also rather fun.

The Mammomat. Has a rather neat carbon fiber um…rack tray, too. Nikon D800E, Zeiss ZF.2 2/50 Makro-Planar. SB900 with umbrella from top right. The bluish color is actually a big glass panel that’s part of the machine; it changes color which supposedly helps keep patients calm.

The session actually started off here, in Mammography – it’s challenging to make a room that’s designed to have some separation between the x-ray source and the operator booth look cosy and inviting. And even more challenging was to show the process with a model patient in a way that didn’t reveal any skin.

The trick with lighting here was to balance the mid-warm ambient fluorescent with flash to provide definition and shadows; I shot manual for all of the exposures at about 0.5-1.5 stops under ambient. A SB900 with umbrella behind and above the subject provided face definition, with a second naked one on the floor provided room fill.

On assignment: Bistro food

_7060396 copy
This set shot with a Nikon D700, AFS 60/2.8 G Micro and several SB900 flashes.

I’m seeing an increasing shift in my commercial work these days towards food – as a gourmet (or perhaps as a greedy person) I’m certainly not complaining. Interestingly, food photography actually shares a lot of techniques in common with watch photography – with the huge benefit of not having any reflective surfaces to worry about. But from a lighting point of view, it’s the same.

Last week, I shot what was probably my final job with the Nikon D700 – some highlights of which are presented here. The D800 studio update will probably be towards the end of next week due to job scheduling.

I wanted to use this opportunity to say a few things about both food photography, and draw some conclusions on the D700’s use as a studio camera.

_7060499 copy

Food may not have any reflective surfaces, but it certainly presents some challenges of its own: firstly, temperature. Things don’t look optimally appetizing for that long (think ice cream) which means you’ve got to work quickly, and studio strobes are pretty much out of the question because the heat would make anything fresh wilt in less time than your fastest flash sync speed. The solution I’ve found to that is either use low-temperature LED panels or use flashes. For the most part, I use flashes because they’re more flexible in terms of light output deliverable, and have enough power to accommodate larger setups. LED panels don’t have as much throw or power, and go through batteries like crazy. And there are also color temperature issues – so far, very few panels can deliver a relatively even, neutral spectrum – and those that can are both hideously expensive and not all that bright.

_7060545 copy

The next challenge is actually detail: most people don’t want to look too closely at what it is they’re eating. I mean, a steak looks great as a whole, but I don’t think you want to start looking at meat fibers and thinking about exactly what motor function that muscle did when it was still part of the cow; there’s a huge compositional tradeoff between detail, suggestion, and emotion.

_7060248 copy

Bottom line: food images are about emotion: they must make you feel like you want to eat them. The ultimate litmus test for me is: would I want to order the dish if I saw this image in a menu? Lighting is your one control here: both softness and position of the light sources, and less intuitively, color temperature. (I’ll go into this more in a future article).

_7061864 copy

I’m going to conclude with a few words about the D700 as a studio camera. It may not deliver the most resolution, but it does have a few advantages over say a D3x or medium format – providing you don’t have clients that must absolutely have that pixel count. Firstly, there’ the built in flash with commander function – that was the #1 reason why I went for a D700 instead of a D3s, and I don’t regret it one bit. Speed isn’t an issue, but putting an ENEL4a in the MB-D10 grip gives you both speed and an incredible amount of shooting time: I can easily shoot a full day assignment on one battery. This assignment (2,000 frames in total) was completed with 60% power left over on the ENEL4a, and the ENEL3e in the camera still full. Finally, base ISO of 200 gives your speed lights a boost – and even if you don’t need the extra power, it reduces cycle time as well as extending your battery life.

_7061009 copy

Curiously, the internal flash can’t handle more than about a dozen shots or so in reasonably rapid succession before it cuts out to take a breather – unclear whether this is due to the capacitor’s limitations, or an overheat protection system of some sort to prevent your prism catching fire (which would probably be a fatal disaster considering the camera is both touching your face and made of highly inflammable magnesium.)

I’m looking forward to the quality the D800 brings, though I can’t say I’m so enthused about the amount of retouching it will require – especially for watches and other similar product. But for food, bring it on! MT

I will be attending the World Gourmet Summit in Singapore at the end of April to conduct some sessions for Leica; details to come soon. MT
