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.

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.
