3.5 Context
Context is the way the viewer of the image creates the story of the primary subject, using the secondary elements in the frame as mental markers. The secondary elements help to place the subject in terms of time, location, culture, era, mood, as well as giving countless other psychological clues such as wealth, poverty, uncertainty, danger, unasked questions, etc. A subject in isolation is fine for a commercial product shoot, but it lacks the emotion and narrative richness that well-framed surroundings can add. The photographer also has to ensure that the elements in the frame have the correct relative prominence, which is to say the framing should direct the eye of the viewer to the primary subject first, and then the secondary subjects in order of importance. If this is not the case, then the message of the photograph can land up being quite different to the intention of the photographer at the time of capture. Properties of a subject that affect relative prominence include size, position in the frame, relative brightness, and contrast/ color vis-a-vis the background.

The importance of context. Leica M9-P, 35/1.4 ASPH FLE

Perhaps the concept of context is best illustrated by an example: let’s take the classic photojournalism shot. Wide angle, strongly directional lighting, some atmospheric haze, angry person waving a gun front and centre standing in a shaft of sunlight, close to the camera. The background scene contains other people grimacing (we think – they’re too small and far from the camera to tell) and greatly reduced in prominence to the primary subject, some destroyed/ burned objects, and a fire, all set to an destroyed building in the background. First thing we think when we see an image like this: war. But what if the angry person wasn’t highlighted in a shaft of sunlight, the camera was closer to the other people, who now turn out to be laughing, and we see that the destroyed background building is actually abandoned and the only one in a relatively prosperous-appearing urban area? Would these two images not have a very different story?

The price of progress. Leica M8, 35/2 ASPH

4. Cultural background and history
There are some images which will never mean anything to any observers outside a closed group of people; this is because the compositional elements and subjects make reference to things that are culturally unique or specific to a historical time period. The trick to making images like this work is that they must have enough context for the viewer to be able to make a reasonably accurate guess at the context, even if they have no idea of the specific references invoked. Good examples would include any sort of cultural or religious ceremonies; historical events that were not publicised outside a particular country; or ethnic differences between different racial groups. (I doubt most viewers would be able to tell the difference between Dinka and Masaai tribespeople, for instance. But there would be enough visual cues in the frame to correctly think ‘Africa’.)

It just has to be Paris. Leica M8, 21/1.4 ASPH

I’d probably widen this to include any technical sort of photography where a good portion of the visual impact comes from the subject – fully conscious of the fact that this also covers a good portion of my own work. I could take images with identical lighting and camera/ subject positioning of say a Lange Datograph and a Lange Double Split, but only the horological afficionados are going to display any meaningful difference in excitement for one image over the other.

Seeking understanding. Leica M8, 21/1.4 ASPH

5. Human psychology
Something related to cultural background – think of it as a collective culture for the human race. There are things that universally invoke a reaction amongst the vast majority of people; for subject matter, this includes anything taboo such as death; anything universally celebrated such as birth or marriage, smiles, tears, tension, anger and anything other strong emotional cues (feel free to add to the comments if I’ve missed anything). The ability to include such cues in a very obvious way in an image further increases the overall impact of the shot – seasoned photojournalists such as those who produce reportage for National Geographic, Time, Life etc are very good at this.

Does this scene make you feel warm? Why? Nikon D700, 85/1.4 G

There’s also a second set of elements related to the human psyche that can form useful toolkit – these include use of color (or B&W); directionality of lighting, and particular hues or shades to provoke a reaction. It can be as simple an image of a place with predominantly warm hues (reds, yellows) feels cosy and inviting; the same place with shifted white balance or cooler lighting resulting in blues and whites can be made to feel clinical and sterile. Part of our response to color is down to conditioning imposed by lifestyle – incandescent light, hearth fires, sci-fi culture, medical clinics etc.# – and part of it is probably a physiological thing from our time in the jungle. It’s well known that in the natural world, brightly colored animals and plants are either that way to attract the attention of mates or other members of their species, or to warn potential predators of toxicity.

No missing the subject here. Nikon D700, 60/2.8G

#I’m sure you all had an image in your mind at every single one of these examples – now think, what was the predominant tone, color or white balance in each of those images? This article goes into the psychology of color in more detail, and this one deals with how to achieve control over color.

Finally, there are compositional rules that most people react to, to varying degrees. These include a preference for balance and symmetry; responding to leading lines, and singling out things inside natural frames. There’s also the expectation of the top of the frame being lighter than the bottom; I’m not sure where this emerges from, but I’m fairly confident it has something to do with the sky being brighter than the ground in real life.

This shot probably means more to me than it does to you, because I’m married to the subject. Leica M8, 35/2 ASPH

6. The personal connection
The one element that the photographer has almost no control over for the majority of his audience – assuming that the image is to be viewed by more than those who commissioned it or who have direct involvement in it – is to do with the personal response of the viewer. A good example would be pictures of a wedding – they’d mean something to me if it was my wedding, and I might even be able to overlook compositional shortcomings because of the moment they capture (though I suspect my wife might disagree) – but to somebody with a detached and critical eye, the images may hold very little merit. Or perhaps a well-executed still life of bananas; I might love fruit and therefore be more inclined to like the image over somebody who’s allergic to them, or perhaps suffered from one too many banana peel pranks as a kid – they, on the other hand, might be made very uncomfortable by the image indeed – and possibly not even know why.

Moral of the story: take some time to understand your audience, and you’ll be surprised at the difference in the response. It’s one of the first questions I always ask a client: is it for you, or your customers? And what would your customers want to see?

Blink and you’ll wonder if you really saw it. Nepal, Nikon D700, 24/1.4G

7. Timing.
This concept is best encapsulated in HC-B’s decisive moment philosophy: unlike with a video, you’ve only got one frame to tell the entire story. This means that everything that has happened, is happening, and will happen in the future must be captured in that one frame; it’s the relationship between the events clearly occurring in the frame, and the cues given from which the viewer’s mind interpolates what’s on both sides of the timeline. Although each of the other factors almost always have multiple possibilities that ‘work’ as an image (albeit with different stories) – there is only ever one decisive moment for each message or story. If you miss it, there are other moments, but they each have a different story. Time is a continuum and an artificial human construct, but at the same time the flow of causality is one-way. (This is getting a bit more metaphysical than intended; for more have a look at this article on the relationship between quantum mechanics and photography.)

City Hall, London. Leica M8, Voigtlander 50/1.1

8. The X factor.
Truly outstanding images have something that goes beyond items 1-6; it’s an unquantifiable something that is perhaps almost born out of luck and chance, and never to be repeated. You have to have the right subject, at the right moment, in the right light, with just enough context to tell the story but not so much as to overwhelm, and some sort of personal or emotional connection created with the viewer. (And if you’re a commercial photographer, you’ll have to create all of this from scratch on demand on a repeatable basis.) I actually think the final part of what makes an image work is a degree of controlled imperfection; this appeals at a subconscious level to the humanity of the viewer; it’s almost as though it says ‘what I saw affected me as much as it should affect you’. (Of course, there is a time and place for this, and in commercial shoots, camera shake is just sloppy.) Finally, never underestimate the importance of luck: being in exactly the right place, at the right time.

Sometimes, the patient are rewarded. Schonbrunn, Vienna. Leica M9-P, 28/2.8 ASPH

9. Conclusion
I want to finish on a high note. Even though there are a lot of elements that one has to manipulate – and a couple that you can’t control – to make an outstanding image, it’s clearly possible, because outstanding images happen all the time. And probably more frequently than we think, too – not all of them are shared with the world; Vivian Maier’s work is a great example of that. The single most important element of all isn’t covered in any of the sections above, and that’s practice and preparation. It’s also the best advice I can give to any photographer at any skill level. No matter how deep one’s understanding of the concepts is, if you don’t have a camera with you, or can’t figure out how to get the effect you want, or find the spot metering button, or accidentally shoot in a thumbnail-sized jpeg or something similar, you’re going to miss the shot. If your eye isn’t trained to passively seek out compositions all the time, then you’re going to miss something. The best thing, however, is that the element of preparedness is 100% under the control of the photographer. MT

What makes an outstanding image? (part 1)

October 6, 2012 By Ming Thein 67 Comments

Of the 400 or so posts I’ve published up to this point, I recently realized that the one enormously gaping hole I haven’t yet covered deals with the one of the major fundamentals: how do you actually determine if an image ‘works’ or not? What makes it good? What makes it outstanding? I think it was both a discussion on composition in our reader pool forum on Flickr, as well as the strongly mixed reactions to this photoessay post that did it – context, even a mini-article, sometimes simply isn’t enough if you’re missing a cultural familiarity, or local view. This is obviously not a simple question to answer; despite an extensive search online, I haven’t been able to find any good articles that provided any sort of conclusion. (Clearly, I must be a bit of a masochist in deciding to write this article.) Perhaps it’s because it’s an extremely subjective question to begin with; or perhaps it’s because to come up with an answer that makes sense requires a thoroughly multidisciplinary approach: strong images resonate technical, compositional, cultural, psychological and personal chords. And the final two are of course highly observer-dependant.

In fact, it’s a wonder that we have any images at all that are globally recognized and appreciated. Rather than analyze specific images, I’m going to spend some time looking into some of the more abstract characteristics and their implications for one’s photography. I’d recommend finding a comfortable chair and grabbing a drink because this is a pretty heavy article. So heavy, in fact, I’ve decided to split it into two parts. It’s also turned out to be one of the most difficult articles to write, occupying a good couple of days thanks to the extremely vague and ill-defined nature of the subject matter. Finding the right photos to illustrate the article was just as tough; excuse me if there are some repeats of previously-posted images here.

One of the most important things for a photographer to know is specifically why one of their images works, and why another one doesn’t. I was going through my contacts’ uploads on Flickr the other day and noticing that there were three types of photographers:
a) upload everything, no QC or editing whatsoever, mostly poor images;
b) upload most things, has one or two really good images, mostly mediocre;
c) only uploads good stuff, and shows a consistent level of quality.

Type a almost certainly has no idea of what makes a good image, or perhaps they don’t really care; we must remember that social media is also used for indiscriminate sharing. Type b appears to be a more serious amateur, and wants to make good images, and probably knows a good image when they see one, but is unable to deconstruct their successful images into a series of things that they can replicate. The final type, c, knows what works, and either doesn’t bother shooting the rest, or hits the delete key pretty fast when something isn’t quite right. I want to get us all to type c.

*Note that this article contains a lot more links than anything before – it’s because I’ve previously explored a lot of these individual concepts in some depth, but never unified them in a single article – this one.

Let’s begin.

1. Subject
There is simply no point to a photograph or image if there is no subject. An image is a representation of something: if there’s nothing to represent, or it isn’t clear what the representation is trying to be, then why bother at all? This doesn’t mean to say that abstract images don’t work; in such cases, the abstraction and entire frame are the subjects themselves. But in the broadest possible sense, if you look at an image and it isn’t fairly obvious what the image is about, then it fails. A photograph without a subject is like a meal with no main course, or a story without a plot – it can fill an immediate transient need, but it will not have any lasting consequence or memorability.

The cloud. Sony RX100

The sole implication for the photographer is that you need to know what the subject of your image is going to be before you take the shot, and how the other elements in the frame relate to it and tell the story. Or maybe they don’t relate to it and create an inverse story of juxtaposition and contrast; it all depends on what you’re trying to say with the image. The subject also needs to stand out and be visually obvious, it should be the (metaphorical and optical) focal point of your image. We’ll deal with that in section three. Bottom line: you need to have a clear picture in your own mind about what the image is about; invariably not everything is executable, so this picture gets increasingly blurred as it comes closer to physical execution – hence ensuring that you start off with as strong an idea as possible is paramount.

2. Execution and technicalities
Next comes the simplest of the ‘secondary’ criteria. Even this is relative, however. Generally speaking, a good image is properly exposed for the subject, is in focus, and doesn’t take processing to the extremes. The executional characteristics of the image should not be the first thing you notice when you look at the photograph: you can overdo it**. They should support the compositions, but not detract of outweigh it. This is one of the things I don’t like about overdone HDR, Instagram and other photo apps – the processing is so overdone to the point that fundamental compositional structure is overshadowed, and any flaws hidden. You only see the processing, and not the subject.

However, there are always exceptions to every rule. And in the case of the technical qualities of an image, if you have an exceedingly strong subject or composition, then no matter how poor your execution, the subject is what you’re going to see first. Nobody remembers Robert Capa’s iconic Normandy landing shots for their technical perfection, but rather the subject matter and how he managed to convey the chaotic, haunting, gritty sensation of actually being there.

Service – with just the right amount of motion blur. Sony RX100

I include processing under technical execution. The biggest fundamental choice you have here is whether to work in color or black and white; some subjects are particularly suited to one or the other; some could go either way. Whether you should use one or the other depends mostly on whether your subject is best isolated by luminance/ brightness or by contrast in color. (This topic is subject to an entirely separate article here.)

**I cover processing workflow in general here, and here for B&W.

3. Composition
In its simplest definition, composition is how the various elements of an image are located relative to one another, and how this spatial relationship tells the story of the main subject or conveys the desired message. However, there are some restrictions – firstly, we are representing a three-dimensional space in two dimensions, and secondly, there are perspectives imposed by the field of view we choose to employ. The reduction to two dimensions has both strengths and weaknesses: you cannot rely on depth perception to create perspective; instead, we have to artificially impose it through our choice of focal length. However, its removal also means that we can do things that aren’t possible via native human vision, such as have everything in the frame simultaneously in focus. Mastery of composition is knowing when to use the right tool to enhance the presentation of the subject.

Dessert, before and after being enjoyed. Nikon D700, 60/2.8G

That said, for any given subject and situation, there is no one perfect composition – rather, there are probably any number of compositions that can work. However, the big difference is that they will not all tell the same story. Again, there is no right or wrong here: the best story for a given situation will depend very much on what the end objective is for the image.

This article and this article both enter into more detail on compositional theory.

3.1 Isolation/ separation/ focus
This concept lacks a single defining word – I suppose ‘focus’ would be closest, but the problem is that tends to induce confusion between the subject distance and the concentration around the idea or subject of the image. The ideal qualitative effect is that the eye of the viewer must go straight to the primary subject of the photograph, and then only on to the context that surrounds it, in the order that the photographer desires. This can be accomplished through the use of a number of different tools – leading lines, natural frames, negative space, bokeh etc. The subject itself must stand out from the background or surroundings; in that sense, some sort of natural frame is always required to provide the necessary isolation – it could be a doorway, or a plain color background of a different color to the subject, or a contrast in texture. The sole exception is a whole-frame abstract, where the entire image is the subject. Note that lighting is the other major source of subject separation. (And yes, there is such a thing as too much bokeh.)

Before the take. Nikon D700, Zeiss ZF 1.4/85

3.2 Perspective
There is no right or wrong perspective for any given subject. The sole aim of perspective is to either emphasize or de-emphasize the foreground relative to the background. Does the subject need to be larger than life, or minimized? Does the image require context to understand properly, and how prominent should these contextual elements be relative to the primary focus of the image?

Trees. Ricoh GRDIII

In general, wide-angle perspectives need a clear subject placed in the foreground. This need for a defined foreground decreases as the focal length increases, to a point where it could really go either way at roughly 50mm and above (35 equivalent). Above that, the foreground and background are of similar prominence, and subject separation is no longer achieved through perspective, insofar as depth of field is a consequence of a particular focal length and perspective. Images shot with a wide lens that lack a clear foreground can work, but only under specific circumstances which almost always involve leading lines, or large amounts of context and unusually good subject separation. Similarly, one must also take care with the use of telephotos – you can focus on the subject to the point of exclusion of all context, which can actually weaken an image.

Mt. Yotei. Nikon D700, Zeiss ZF.2 2/100 Makro-Planar

3.3 Balance
I’ve always found this to be one of the more difficult things to define. Instinctively, you know whether something is balanced or not on looking at it – but what it is specifically that creates, or destroys, that sense of balance is much more difficult to quantify. The eye of the viewer needs to linger for about the same amount of time in every portion of the frame; if you have half of the frame that takes a split second to understand but produces no context, against the complex opposite half of the frame where there’s a lot going on and a few moments of deciphering are required, then you generally might as well not bother with the quicker part.

Breguet Tradition. Balanced, but not perfectly symmetric. Nikon D700, 60/2.8G

Doesn’t make sense? Boil it down to opposites. Balance is like symmetry, but not quite; the mirror images do not have to be identical, nor do they have to be symmetric around the dead center of the frame. If the left half of your frame has something in it, then the right half must too, of roughly the same size and level of detail. This is independent of the subject. Now quarters: you can do opposite top-left and bottom-right and leave the other two corners empty, but if you do three corners and omit one, the eye is going to go straight to the empty corner because it’s the odd one out. You might actually want to do that, but make sure it’s a conscious choice. You can keep subdividing your frame and finding opposing points around the middle to balance out, but generally once something gets to be say less than 10% of the frame size in any linear dimension (1% area) then it’s usually inconsequential enough to ignore – so long as it doesn’t intrude into your subject.

This of course also applies to your subject too: don’t make it too small, otherwise no matter how balanced your frame, it won’t stand out!

There are always exceptions to every rule. Nikon D800E, Zeiss ZF.2 2/100 Makro-Planar

3.4 Lighting
I just completed a whole series on lighting here – intro to equipment, part 1, part 2, part 3, part 4, and tips and tricks.

With no light, there can be no photography. The direct meaning of ‘photography’ is ‘writing with light’. Light identifies and isolates your subject; the softness or hardness or uniformity of it determines the amount of definition and contrast, as well as the tonality; the color and hue determine the feeling of the scene. And the absolute amount of it has an impact on the technical quality of the image, too. It’s inescapable that every good image must have good light – you can make an ordinary subject into an arresting photograph if it’s properly lit, but no amount of photoshop or the most unusual object is going to surmount flat or uninteresting light.

Prague. This would not be interesting on a flat, gray day at noon. Olympus E-PM1 Pen Mini, 45/1.8

Photographers must therefore either be able to recognize when the light is right, and seek out subjects to be illuminated by it – or go one step further and learn to control it. In fact, you have to do the former before you can do the latter – understanding the origin of a particular look makes it much, much easier to reverse engineer and replicate. Distilling things further, we’re arrive at the inescapable conclusion that successful lighting hinges on directionality, nothing more and nothing less. The right directionality creates the right kinds of shadows and highlights, which in turn creates contrast, texture and subject definition. And the less common the direction (light), the better – why do you think psychologically, we don’t find images shot in noon sunlight or under common indoor artificial light to be particularly arresting? It’s because that’s what we are conditioned to seeing most of the time. However, golden hours or special lighting effects are much less common. But I’m starting to digress into psychology, which I’ll leave for section 5.

Come back tomorrow for the conclusion in part two.

Workshop report: 28 Sep Making Light in Kuala Lumpur

October 3, 2012 By Ming Thein 16 Comments

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?

A simple one-light portrait. Nikon D800E, Zeiss ZF.2 2/100 Makro-Planar

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…

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

…including setups involving two lights:

…harsh contrast…

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

…the addition of beauty dishes to balance out the background to provide a clean white look with flattering light bleed around the edges of limbs and torso…

Setup shot

…some occasional theatrical emoting from the coach…

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

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!

Lighting tips and tricks

October 2, 2012 By Ming Thein 1 Comment

A little bonus to follow on from the previous five part series* on lighting.

*A primer on lighting equipment is here. Part one on single sources can be found here; part two on multiple sources, here; part three on balancing ambient, here; part four on continuous sources, here.

There are a few things worth bearing in mind when creating your own lighting:

There should always be a top.
This usually means lighting in such a way that the orientation of the subject is obvious; it doesn’t always mean that it has to be shot in this orientation. Often, this is physically impossible with some subjects. But what you can do is rotate camera, place your stronger light sources at the perceptual ‘top’ of the subject, then rotate the image afterwards. I frequently do this with watches – they don’t stand up by themselves!

DIY
Not all lighting equipment has to be bought. Some can be made at home – a rolled cardboard cone makes a fine snoot; you can cut gobos out of mount board with a hobby knife, and even softboxes can be made from wire and mount board with a little forethought. The most critical bit of equipment in my own arsenal – the watch diffuser – I made myself.

Start simple
Beginners often make the mistake of buying too many lights, stands, umbrellas etc. and then trying to deploy them all at once – you often don’t need to. The most effective, dramatic lighting setups usually only require one, or at most two, sources. Only increase the complexity of your setup if you absolutely have to – remember the number of variables for each light in the first article on single sources?

Use what you’ve got
Building on starting simple, often ambient light is both difficult to replicate and offers invaluable context. Don’t overlook it in your quest for control of light: it can be very helpful indeed. This is where the next tip comes in:

Master manual metering
Controlling all of the exposure parameters manually gives you perfect control over the relationship between ambient and made light; if you’re particularly masochistic or have a difficult subject (reflective objects for instance) you might even go manual for the flash output, too. Learn to visualize what various exposures look like, and you can both work a lot faster, and create better results, too.

Imperfection is perfection
Natural light is never perfectly even, or diffuse, or directional; it’s the little variations and imperfections caused by shoddy internal baffling in your home-made softbox that gives an image character. Embrace the imperfection, and let it work for you.

Watch your color termperatures
You can use a difference in color temperature between sources (differently gelled flashes, or ambient vs flash etc.) to isolate a subject or different zones in your image. You can also overdo it and land up with very strange color in some parts of your image; as with everything, just enough is the difference between something different and something overcooked.

There is such a thing as too much diffusion
Very large, flat sources are great when shooting a large object, but remember that the only thing that defines the shape of an object – any object, be it a car or person or watch – is the way the shadows and highlights fall. If you have very flat, even light, then you might find there is very little distinction between shadow and highlight; this is great for maximizing dynamic range, but it’s also going to make your subject look incredibly flat, too. What does work with such sources is to use the big soft light as the secondary source, dialled in a a stop or two below your primary source – something harder, and more directional, to maintain texture and shape in your subjects.

Zoom head settings don’t have to match lens position
Flashes have internal mechanisms to move the tube and/or reflectors and fresnel grids around so that the angle of coverage of the beam matches the angle of view of the lens used; this doesn’t always have to be the case. If you use a narrow beam with a wide lens, you create a spotlight effect; this can be useful to highlight a particular subject. Just don’t make the difference in exposure too great, or it’ll look unnatural.

High sync speed and lots of power are your friends
Higher sync speeds enable you to do many things: freeze motion, fill in very bright sunlight, and use less power while doing so. It isn’t so much a special trick on its own per se, but more of a means of extending your shooting envelope so you have more control and more options when ambient light is extremely bright. And more power means more control over apertures, more ability to use diffusers and modifiers (they all eat light – at least a stop, sometimes as much as two or three) without compromising range or depth of field.

Deconstructing light, part four: continuous sources

October 1, 2012 By Ming Thein 12 Comments

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?

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.

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.

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.

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.

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.

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.

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

September 30, 2012 By Ming Thein 12 Comments

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.

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).

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.

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.

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.

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.

Deconstructing light, part two: multiple sources

September 29, 2012 By Ming Thein 13 Comments

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.

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.

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.

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.

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.

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.

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.

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.

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

September 28, 2012 By Ming Thein 23 Comments

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.

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!

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.

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.

Come back tomorrow for part two. MT

Lighting equipment: a primer

September 27, 2012 By Ming Thein 34 Comments

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.

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.

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
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.

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/ 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
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
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
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.

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

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
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.’

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
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
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
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
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
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

Review: The Olympus ZD 60mm f2.8 Macro and FL-600R wireless flash system

September 21, 2012 By Ming Thein 91 Comments

Although ‘development announced’ (i.e. officially leaked) several months ago together with the 75/1.8, Olympus’ newest macro lens – the M.Zuiko Digital 60mm f2.8 (hereafter known as the ZD60) was formerly announced at Photokina 2012, and should be available sometime in October 2012 at a price of around RM2,000. It’s also only the second macro lens available natively with a Micro Four Thirds mount (and autofocus), the other one being the Panasonic-Leica 45/2.8 Macro-Elmarit, which I reviewed earlier here. Being an OM-D shooter, and heavily product-photography oriented, I was invited by Olympus Malaysia to review the ZD60 together with the new PEN Lite E-PL5 (review coming in the next week or so). The macro work I do almost always involves flash, so I had them loan me a set of their most recent flashes – the FL-600R. This review will therefore be approached from the point of view I’m most familiar with: photographing watches with speedlights, in a pretty much identical manner to how I do it with my main Nikon system. There will be comparative notes throughout, and no pictures of flowers, cats, eyes, coins, trinkets or other typical macro subjects. Let us begin.

All images in this review were shot with an Olympus OM-D and FL-600R wireless flashes; the images are all from the ZD60, except the images of the ZD60, which were shot with the PL 45/2.8.

Let’s talk about the lens first: it offers 1:1 reproduction ratio at a minimum distance of 19cm from the sensor plane, which translates into a healthy 7-8cm of working distance at maximum magnification. This is great news for people who want tight frame coverage; by comparison, if I try to get the same subject coverage (i.e. 2:1 on full frame) with my D800E and Nikon 60 macro, I’m down to around 4 of working distance, which makes even lighting control much more difficult. The optical design has 13 elements in 10 groups, with one ED element, two HR elements and one E-HR element (I presume these are different types of optical glass).

Optical design and MTF chart. From Olympus Malaysia

Three of the groups float and perform focusing functions. This is not a simple optical design! There are traces of a double-Gauss base design in there, but it looks as though heavy modifications and extra elements were added to optimize resolution and close range performance. By comparison, the excellent Nikon AFS 60/2.8 G Micro – which has been my mainstay lens up til now – has one less element and one less group.

Size-wise, it’s similar to the 12-50 kit lens for the OM-D; build quality is definitely better, but still plastic and nowhere near as nice as the 12/2 and 75/1.8 lenses. The plastic used is matte, feels reasonably robust, but curiously has visible moulding lines in several places – I’ve not noticed this on any of the polycarbonate-shelled Nikon or Canon lenses before, but it may be because those tend to have a spatter-finish paint that hides the seams better. It’s also weather sealed, with ‘SPLASH PROOF’ in big letters on the bottom of the lens barrel. The lens is made in China.

Two small points of interest on the ergonomics of the lens itself – firstly, although the (optional, shame on you, Olympus) hood is a bayonet fit, it telescopes in and out; neat, but I found it annoying after a while as if you support the lens by the hood and put too much pressure on it, the hood will easily shift or start to collapse back in. Second is the little rotary knob to control the focus range, accompanied by a pointer scale showing the subject distance and corresponding magnification level. The switch has several settings – full range, 0.4m to infinity, 0.19m to 0.4m, and a sprung detent to take the lens to 1:1. It sounds clunky but is actually very practical in use – selecting the right range keeps focusing fast and positive, and the 1:1 position is very helpful in traversing the focusing range when you don’t have a full-time mechanically coupled focusing ring. Overall, ergonomics are excellent.

100% crop of the above.

Once in a while, (though increasingly frequently with today’s computer-designed optics) you come across a lens that is truly outstanding – the last two that come to mind were the Olympus ZD 75/1.8 and Leica 50/2 APO-Summicron-M ASPH. I’ve used a number of competent, but imperfect, lenses in the meantime, none of which were that memorable for their optics. Fortunately, the ZD60 is another one of those lenses that falls into the ‘truly outstanding’ category – I’ve tried hard under many varied test conditions to find fault with the optics, and come up with an extremely short list. If you want the short answer, you can skip the next few paragraphs: this lens offers excellent optical performance at every aperture and focus distance.

The lens has an even more impressive MTF chart than its highly-regarded predecessor, the ZD 50/2 macro for Four Thirds; granted, both designs only have to cover the small Four Thirds frame, and they used a lot of elements to do it, but still: it clearly outresolves the OM-D’s sensor, even wide open. On my copy, I simply didn’t see any improvement in stopping down – you get increased depth of field, and sharpness stays constant (i.e. outstanding) at every part of the frame. There’s diffraction beyond f8, and that’s about it. The plane of focus is also flat, as far as I can make out, and there’s almost zero distortion present. Let’s just say that the ZD60′s resolving power is not going to be the reason for any soft images. Like most of the extremely sharp lenses, the ZD60 also has very high microcontrast – these characteristics are related because high resolving power is required to differentiate between subtle tonal differences in the subject. In fact, it’s amongst the best lenses I’ve ever seen; deserving of the superlative classification (for lenses, at any rate) – of transparent.

For reference, the screws on the right are about 1.5mm across.

Although overall resolution would support a much higher-density sensor, it wouldn’t be practical in use: on the OM-D’s 16MP sensor, you already have minor diffraction from f8, and visible diffraction at f11 and up (even though the lens can stop down to f22, I really wouldn’t recommend it; you might as well use a pinhole at that point). I suppose it would have been nice if it had tilt control too, but I think given the target market for Micro Four Thirds, that option might be a long time coming. I believe Novoflex has a T/S bellows system, which might be worthy of investigation at some point in the future.

Jaeger-LeCoultre Reverso Latitude.

As for the other optical qualities of the lens – bokeh, chromatic aberration, color rendition and transmission – there are very few flaws. The only one I could find was some slight texture in the bokeh, and even then only in a couple of frames with circular out of focus highlights at a certain brightness level – one of the signatures of a moulded hybrid aspherical element somewhere in the construction. To keep things in perspective, even the Panasonic Leica 45/2.8 Macro exhibits this trait, and more obviously. Aside from that, bokeh is smooth and pleasant, with very minimal bright edges on defocused highlights. Chromatic aberration was nonexistent laterally, and more commendably, almost completely absent longitudinally, too, even wide open. I have not seen this level of CA performance in any macro lens I’ve used to date, even the Leica 120/2.5 APO-Summarit-S. Color rendition is neutral and pleasingly saturated, and taken in tandem actually quite reminiscent of the Zeiss lenses. Olympus uses their new ZERO coating on the lens, which keeps transmission high – I would estimate the lens to be around T3.0.

The ZD60 uses Olympus’ MSC system, which has the elements moving linearly on a rail; it’s not as fast as the 12/2 or 45/1.8, but with the limiter in the 0.4m-infinity position, it’s similar in speed to the 75/1.8, and definitely faster than the Panasonic-Leica 45/2.8.

FL-600R compared to the Nikon SB900. One would fit in your pocket; pocket the other and you’d probably be arrested on a public indecency charge.

Next up, we have the FL-600R flash; it has a guide number of 50m at ISO 200, or 36m at ISO 100, running off four AA batteries, with a wide panel and zoom head covering from 16 to 85mm. Full-power cycle time is claimed to be 2.0s with NiMH batteries; it didn’t feel any slower than my Nikon SB900s or SB700s, which I find to be pretty fast. In addition to the usual TTL and manual modes, the flash can also act as both wireless commander and slave using Olympus RC system. It’s also got a bright single LED in the base portion – ostensibly for video use, but I actually found it to be a useful modelling light for macro work, making focusing and composition quite a bit easier. If only it was in the head itself and even brighter…

In use, the flashes are fairly simple to operate, though the very low number of external controls means that a lot of button presses are required, and you have to remember what does what – I much prefer the softkey and physical switches approach of the SB900 and SB700. That said, the units are physically much smaller than even the SB700 and SB600, and positively dwarfed by the SB900 – this leaves very little real estate on the back for the LCD and controls.

Overall, I found TTL flash exposure to be mostly good; wireless TTL on the other hand, was a bit hit and miss. There were certain situations – specifically when one flash was firing at the background, and the other at the subject – where the subject exposure was a bit inconsistent. Not much of an issue, I just dialled in manual power. The limited external controls and display space also mean that adjusting settings for remote flashes with the FL-600R as master isn’t so easy, and requires far more button presses than I would like. Fortunately, even with the FL-600R on the hotshoe, the camera itself can be used to set the remotes; the hot shoe contacts then transmit the data to the flash. Coupled with the OM-D’s touchscreen, it’s a fast and easy experience – in this respect, better than the Nikon system. And you can control all three groups of flashes from the camera, regardless of which flash is attached to the hotshoe – which is one more than the Nikon system. There are also three available channels so other users’ flashes aren’t triggered by yours and vice-versa if there are a few of you. I can see this being useful if you shoot Nikon or Canon, but to be honest, I’ve never encountered an Olympus flash shooter…

The only major issue I have with the wireless flash system is triggering – the sensor on the flash unit itself seems to be very small, aimed forwards and somewhat recessed – this makes no sense whatsoever, seeing as the flash is likely to be facing the subject, which means that the sensor will be away from the camera. Even the Nikons – with side and front mounted sensors – still have problems picking up the optical trigger signal at times. With the FL-600Rs in orientations where the sensor wasn’t almost facing the camera directly, triggering was somewhat hit and miss, especially with the small flash supplied with the OM-D. Use of one of the FL-600R units as a master improved this somewhat, but camera companies really need to start making flashes with multiple optical sensors, or better yet, built in radio triggers for both camera and flash. I know some of you might suggest external radio triggers, but has anybody tried looking for a TTL PocketWizard for Olympus lately? It just doesn’t exist.

To date, when using the OM-D for macro work, I’ve either been using my large LED panels (and hence continuous lighting) or the SU-4 optical slave mode on my SB900s and the supplied small flash set to 1/64 power, which works well, but lacks the convenience of being able to set the power output from the flashes either via TTL metering or directly from the camera, let alone both. This can be inconvenient at the best of times – worse still if your flashes aren’t easily accessible. I’ve wanted to try the Olympus wireless flashes for some time now; my thoughts are that so long as you can spare one unit to use as a master trigger, they’re a viable alternative to the Nikon system; the problem is that I’d have to buy another five flashes to get the same flexibility as I have now, which seems somewhat silly.

That said, the Olympus system – and Micro Four Thirds – for macro work has a lot going for it; firstly, a truly outstanding lens which is almost completely CA-free; flashes that aren’t that expensive, and very, very small – like the rest of the system. I could fit an equivalent system to what I use now in a bag half the size. Although on the face of things, the Nikon system has a huge resolution advantage – you lose something in diffraction (despite the D800E not having an AA filter), and the OM-D files are clean enough to upsize well to 25MP or so. The difference is much less than you might think. I think I’d have a very difficult time deciding what to buy if I was starting over again with the same objectives. As it is, I won’t be returning the ZD60 to Olympus; it’s unquestionably earned a place in my arsenal, edging out the 45/2.8 (it’s also nice that I no longer have a focal length overlap with the faster 45/1.8). As far as I’m concerned, this is the new reference lens for Micro Four Thirds. It’s that good. MT

On assignment and studio review: Watch photography with the Leica M9-P

April 13, 2012 By Ming Thein 25 Comments

We photographers are a strange lot: sometimes we make our lives difficult when there’s absolutely no need to. I recently shot a watch photography assignment using a Leica M9-P, of all things. (This setup has been the subject of another post, here)

You probably know that my usual rig for this is a Nikon with a whole bunch of extension tubes. Why did I do it, you might ask? See the end of the post for the answer.

Let’s start back-to-front, with a few highlights from the results:

Deep Sea Chronograph.

I would conservatively say that this was the most difficult shoot I’ve ever done, and the only one that required the services of an assistant – normally, I find they just get in the way and it’s much faster for me to do what needs to be done rather than have to explain it. Firstly, this rig is one which does not focus to infinity, is entirely manual, and is both heavy and unwieldy. Put one finger wrong and you’re liable to make a hole in the bellows, which being the better part of half a century old, is extremely fragile. (The mechanical parts are still in amazingly good condition though, and operate very smoothly.) You need to set magnification first – also restrictive, between about 2.5:1 to 1:2 only (with the Visoflex and 90/4 only) – then move the entire rig to frame – and because it’s unwieldy, you can’t do this handheld. I made a kind of gimbal head out of a Manfrotto 468RC0 Hydrostat head tilted at 90 degrees, to which was vertically mounted a Manfrotto geared focusing rail, with the rail on the Bellows II attached at right angles to that – which allowed me tilt and yaw motion, and precise front/back and up/down movements. Slow going – there were ten adjustment points on support system alone, to say nothing of photographic controls – but accurate.

Duometre a Quantieme Lunaire 40.5

Secondly, the Visoflex prism obviously blocks the M9-P’s hotshoe, ruling out the use of flashes – at least by any conventional means. With a custom-fabricated cable (read: a hotshoe cover with holes made in it to thread through speaker wire, which was then soldered to the contact points of a donor slave – in this case, a Nikon SB700), it was possible. The slave flash would fire at minimum power and trigger the other flashes in SU4 optical slave mode. Optical slave mode is a polite way of saying 100% manual – so it’s either light meter (which I don’t have) or experience (which I do have, from shooting the same thing with slide film). My assistant would run from flash to flash poking buttons and turning wheels in response to cryptic instructions like “top, up one; back, thirty-two and fifty millimeters, up ten degrees; kill the right one.”

[Translation: Top flash, increase power by one stop. Back flash, change power to 1/32 and zoom head to 50mm, tilt the head up ten degrees. Turn off the right flash.]

Amvox World Chronograph

It was a near thing. The entire job relied on a single critical part: that sync cable. At one point, there was an internal short somewhere which either kept the flash firing frequently enough to trigger epilepsy, or not firing at all. And to compound things, I suspect the trigger voltage of the hotshoe and flash didn’t agree, which would occasionally cause the M9-P to not fire its shutter at all. And then the Visoflex jammed…let’s just say the Victorinox earned its keep on that day.

Duometre a Quantieme Lunaire 40.5

It took me just over nine hours to make a final cut of 80 photographs – which is excruciatingly slow, considering I’ll normally do three times that number in two thirds of the time. Most of the delay was due to moving and setting the camera, or fine-tuning the flashes.

Duometre a Spherotourbillon

However, I think this conclusively proves that the Leica M system is a lot more versatile than most people think. Now, if only Leica would produce modern versions of these accessories – and perhaps something to trigger a flash. I don’t think most people have any idea how difficult it is to find a Bellows II-screwmount to Leica M adaptor until you look…

Master Ultra Thin Reserve de Marche

One quick comment on image quality: the 90/4 Macro-Elmar is a superbly sharp lens with great micro contrast, if you use it in the optimal range. At maximum aperture (f4), there is very visible chromatic aberration – both longitudinal and lateral. Stopped down between f5.6 and f11, it’s superb. At f16, diffraction suddenly kicks in – there’s a huge difference between f13 and f16, it’s as though somebody has run a Gaussian filter over the entire image. (I think at this magnification it’s probably closer to f32, though). I wouldn’t even go near f22. I had to pay careful attention to lighting with the M9, for the simple reason that its dynamic range is probably 2-2.5 stops less than the D800 at base ISO. All in all though, I think you’ll agree that the combination is capable of some spectacular results – even more impressive considering that it was never designed for this.

Because we photographers have a particularly odd fascination with checking out other people’s equipment, I’m going to leave you with some gear shots. I will also say that if anybody is in the market for a tripod head, the Manfrotto Hydrostat series is truly excellent – it’s the only head I’ve ever used that doesn’t exhibit any ‘droop’ when locking down the head, no matter the weight or magnification of the camera and lens combination attached. It’s rock solid.

Yours truly at work. (You’ll notice I’m not using the tripod here; I put it aside for the further-away shots of whole watches.)

My exhibition of fine art horology sponsored by Jaeger Le-Coultre and Leica will be on display at Starhill Gallery, Bukit Bintang, Kuala Lumpur from 3 May onwards – please drop by if you’re in town! If you let me know in advance, I’ll try to give you a personal tour. MT

10X10: 100 ways to improve your photography: Lighting

February 22, 2012 By Ming Thein Leave a Comment

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.

Disclaimer: As with every other article in this series, I’m assuming you know the basics already.

My current array of lighting: three SB900s, one SB700, two 120-LED daylight balanced continuous panels.

10: Always shoot in manual mode. 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.

Inspector. Note how inside/ outside luminance is balanced. Nikon D3, 24-70, one SB900 in a soft box.

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.

Shoddy baffling adds character! D200, 17-55/2.8, 2xSB600s in homemade soft boxes.

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.

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.

Unrelated shot. Speake-Marin perpetual calendar. Nikon D700, 60/2.8 G, one SB900 and diffuser.

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.

The Hollywood shot. Flashes duct taped to curtain poles. Seriously. D3, 24-70/2.8 and three SB900s

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.

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.

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.

Dessert. Balanced with ambient daylight in restaurant. Nikon D700, Zeiss 2/28 Distagon, 2xSB900

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.

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. MT

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.
