PALING BY COMPARISON

A good sunset to the naked eye, but rendered very blue by the camera’s auto white balance setting.

By MICHAEL PERKINS

GIVEN HOW MANY PICTURES YOU NEED TO SHOOT, over a lifetime, to develop the kind of eye that will deliver more keepers more often, you have to make peace with the taking of many, many images that do not, strictly speaking, “matter”. They’re either uninteresting or indifferently executed or mere technical exercises that don’t emotionally stick. However, that does not mean they are a waste of time, since the practice meter is running whether you’re making magic or mud. And with some mindfulness, you can get into the habit of  harvesting something worth knowing, even in the most mundane of shoots.

Just straying from your standard procedures in very small particulars can show you new options for shaping or salvaging a photo. In the two comparison shots seen here, there is only one thing that distinguishes the first picture from the second one; the camera’s white balance setting.

Same shot, same exposure, but with a switch to the camera’sshadewhite balance setting.

I just am not a fan of shooting on auto modes or default settings, for the simple reason that they are designed to produce average, not extraordinary pictures. They prevent us from making a total dog’s breakfast of an image, but they also deny everyone choice except, weirdly, the camera.

On the particular shooting expedition seen here, I was seeing a warm, full-on golden hour of pre-sunset, the rich oranges and browns visible even in shade. However, the camera’s auto white balance, which reads the temperature of light to “see” white the way we do, was delivering a lot of blue. The simple switch to a “shade” setting rendered even the deepest shadows as warmly as my eyes did.

The point is, this image was part of an uneventful afternoon’s casual stroll, yielding nothing in the way of “legacy”-level work. It was simple journeyman practice. What makes such tiny technical decisions valuable is how instinctual they can become when repeated over thousands of pictures, how available they become as tools when the picture does matter. Pictures come when they’re ready. With luck, building on the lessons from all those “nothing” pictures mean you’ll be ready as well.

OFF-WHITES AND NEAR COLORS

ONE OF THE MOST GRAPHIC DEMONSTRATIONS OF THE DIFFERENCE BETWEEN YOUR EYE AND A CAMERA’S occurs by accident for most photographers, with variations in the reading of white balance that make the colors in an image look “wrong”. While our own vision looks at everything in the world from light blues to medium greys and instantly converts them all to “white”, the camera makes looks at all those variants and makes what can be called its best guess.

All light has a temperature, not a measure of heat but an index of which colors combine to deliver hues of a certain intensity and range, and white balance helps photographers manage color more effectively. Film shooters, especially those using sophisticated flash technology, eventually develop an instinct as to which kind of light will deliver the hues they seek, but, as the digital era tracks onward, many more of us simply rely on our camera’s auto settings to deliver a white that strikes us as “correct”. And when auto white balance fails to deliver the goods, we can override it and select other settings that compensate for incandescent light, shade, cloudy skies, and so forth. We can also create a completely custom white balance with little fuss. Think Dad looks better with a green face, like the true extra-terrestrial that he is? It’s at your fingertips.

The fun starts when you use white balance to depart from what is “real” in the name of interpretation. WB settings are a fast and easy way to create dramatic or surreal effects, and, when you have enough time in a shoot to experiment, you may find that reality can be improved upon, depending on what look you want. In the top image, taken during a long, lingering sunset at sea, I had plenty of time to see what my camera’s custom WB settings might create, so I bypassed standard auto WB, then amped up the reds in the sky by clicking over to a shade setting, resulting in a deep and warm look.

For the second shot of the same scene, I wanted to simulate the look of a sky just after sunset, when the blues of early evening might take over for the vanished sunlight, even providing a little radiance from a pale moon. One click to the setting and you see the result. Now, of course, I’ve just switched from one simulation of reality to another, but playing with WB in a variety of lighting situations can help you tweak your way to fantasy land with no muss or fuss.

Tweaking white balance is basically lying to your camera, telling it that it is not seeing what it think’s it’s seeing but what you want it to think it sees. You’re the grown-up, you’re in charge. “White” is what you say it is. Or isn’t.


DON’T EVER ALWAYS DO ANYTHING

IF YOU’VE EVER GLANCED AT THE NORMAL EYE’S HOME PAGE MISSION STATEMENT, you might come away with the impression that I am unilaterally opposed to automodes, those dandy little pre-sets that do their best to predict your needs when making a photo. The truth is that I am against doing anything “all the time”, and thus caution against the universal use of automodes as a way of idiot-proofing your shoots. They can be amazing time-savers, sometimes. They are reliable shortcuts, sometimes. Just like I sometimes like bacon on a burger. There are no universal fixes.

I meet many people who, like myself, prefer to shoot on manual most of the time, eschewing the Auto, Program, Aperture Priority and Shutter Priority modes completely. Oddly, many of these same people almost never take their white balance off its default auto setting, which strikes me as a little odd, since the key to color photography is getting the colors to register as naturally as possible. Auto WB is remarkably good at guessing what whites (and in turn, other hues) ought to look like in a pretty wide variety of situations, but it does make some bad guesses, many of them hard to predict.

A gross-oversimplification of white balance is that it reads the temperature of light from cold to warm. Colder temp light runs bluer. Warmer temp light reads more orange. Auto WB tries to render things as naturally as it can, but your camera also has other customizable WB settings for specific situations, and it’s worth clicking through them to see how easy it is to produce subtle variations.

In the picture in the upper left corner, I’m taking a picture indoors, in deep shade, of a reproduction 1930’s Bluebird Sparton radio, a wondrous Art Deco beauty featuring a blue-tinted mirror trimmed in bands of chrome. To emphasize: blue is the dominant color of this item, especially in shade. Shade, being “colder” light, should, in Auto White Balance mode, have registered all that blue just fine, but, in this case, the chrome trim is completely (and unnaturally) painted in the same orange glow. As for the blue values, they’re well, kind of popsicle-y . That’s because, when it’s all said and done, Auto White Balance is your camera’s educated guess, and it sometimes guesses wrong. If you always use it, you will occasionally have to eat a bad picture, unless you take action.

I get blue when I listen to the radio, or when I dial up the appropriate white balance.

I get blue when I listen to the radio, or when I dial up the appropriate white balance.

For the above image, I want the dial to be nice and orange, but just the dial. To try to get the blues back to normal on the rest of the radio, I switch to the Tungsten white balance setting (symbolized by a light bulb, since they burn, yes, tungsten filaments), something I normally wouldn’t do in either daylight or shade, but hey, this is an experiment anyway, right? To make it even weirder, Tungsten might read neutrally in some kinds of indoor night settings…but it also doesn’t behave the same way in all cases. In this case, I caught a break: the orange in the radio dial registers pretty true and all the metals are back to shades of silver or blue.

Notice how both white balance settings, in this strange case, both performed counter to the way they are supposed to. One misbehaviour created my problem and another misbehaviour solved it. Hey, that’s show business.

Hence the strange but appropriate title of this post. Don’t ever “always” do…anything. If you want the shot you want (huh?) then pull an intervention and make the camera give it to you. Automode in white balance is just as fraught with risk as any other automatic setting. It works great until it doesn’t. Then you have to step in.

 


IT’S UNNATURAL, NATURALLY

By MICHAEL PERKINS

ONE OF THE MOST FREEING PARTS OF PICTURE MAKING IS RELEASING YOURSELF FROM THE RIGIDITY OF REALITY. Wait. What is he babbling about? Don’t photographers specialize in reality?

Well, yeah, the photographers who work at the DMV, the city jail and immigration do. Also the guy in Wal-mart HR who made your first employee badge. Other than that, everyone is pretty much rendering the world the way they see it right this minute, with more revisions or re-thinks coming tomorrow. And beyond.

Color processing, once the sole domain of the “photo finishers” has now been taken back in-house by pretty much everyone, and, even before you snap the shutter, there are fat stacks of options you can exercise to recast the world in your own image.

The practice of bracketing shots has made a bit of a comeback since the advent of High Dynamic Range, or HDR processing. You know the drill: shoot any number of shots of the same subject with varying exposure times, then blend them together. But bracketing has been a “best practice” among shooters for decades, especially in the days of film, where you took a variety of exposures of the same scene so you had coverage, or the increased chance that at least one of the frames was The One. Today, it still makes sense to give yourself a series of color choices by the simple act of taking multiple shots with varying white balances. You can already adjust WB to compensate for the color variances of brilliant sun, incandescent bulbs, tube lights, or shade for a more “natural” look. But using white balance settings counter-intuitively, that is, against “nature”, can give your shots a variety of tonal shifts that can be dramatic in their own right.

In the image above, the normal color balance of the gallery entrance would have rendered the bust off-white and the outer vestibule a light grey. Shooting on a tungsten setting when the prevailing light was incandescent gave the interior room a creamy orange look and amped the vestibule into deep blue, setting the two areas sharply off against each other and creating a kind of “end of day” aspect. I shot this scene with about five different white balances and kept the one I liked. Best of all, a comparison of all my choices could be reviewed in a minute and finished by the time the shutter clicked. Holy instant gratification, Batman.

TIME LIMITS US IN EVERY PHOTOGRAPHIC SITUATION: LIGHT HEMS US IN EVEN FURTHER. Of course, the history of photography is rife with people who refuse to just accept what time and nature feel like giving them. In fact, that refusal to settle is source of all the artistry. Too bright? Too bland? Wrong time of day? Hey, there’s an app for that. Or, more precisely, a work-around. Recently, I re-acquainted myself with one of the easiest, oldest, and more satisfying of these “cheats”, a solid, simple way to enhance  the mood of any exterior image.

And to bend time… a little.

Same scene, taken within a minute of the one above, but with normal white balancing and settings of 1/250 sec., f/5.6, ISO 100, 35mm.

Same scene as above taken just seconds later, but with normal white balancing and settings of 1/250 sec., f/5.6, ISO 100, 35mm.

It’s based on one of Hollywood’s long-standing budget-savers, a technique called day-for-night. For nearly a century, cinematographers have simulated nightfall while shooting in the daytime, simply by manipulating exposure or processing. Many of the movie sequences you see represented as “night” are, in fact, better lit than any “normal” night, unless you’re under a bright, full moon. Day-for-night allows objects to be more discernible than in “real” night because their illumination is actually coming from sunlight, albeit sunlight that’s been processed differently. Shadows are starker and it’s easier to highlight what you want to call attention to. It’s also a romantically warm blue instead of, well, black. It’s not a replication of reality. Like most cinematic effects, it’s a little bit better than real.

If you’re forced to approach your subject hours before sunset, or if you simply want to go for a different “feel” on a shot, this is a great shortcut. Even better, in the digital era, it’s embarrassingly easy to achieve: simple dial up a white balance that you’d normally use indoors to balance incandescent light. Use the popular “light bulb” icon or a tungsten setting. Indoors this actually helps compensate for cold, bluish tones, but, outside, it amps up the blue to a beautiful, warm degree, especially for the sky. Colors like reds and yellows remain, but under an azure hue.

The only other thing to play with is exposure. Shutter-speed wise, head for the high country

at anywhere from f/18 to 22, and shorten your exposure time to at least 1/250th of a second or shorter. Here again, digital is your friend, because you can do a lot of trial and error until you get the right mix of shadow and illumination. Hey, you’re Mickey Mouse with the wizard hat on here. Get the look you want. And don’t worry about it being “real”. You checked that coat at the door already, remember?

Added treats: you stay anchored at 100 ISO, so no noise. And, once you get your shot, the magic is almost completely in-camera. Little or no post-tweaking to do. What’s not to like?

I’m not saying that you’ll get a Pulitzer-winning, faux-night shot of the Eiffel Tower, but, if your tour bus is only giving you a quick hop-off to snap said tower at 2 in the afternoon, it might give you a fantasy look that makes up in mood what it lacks in truth.

It ain’t the entire quiver, just one more arrow.
