POST STARTS NOW
By MICHAEL PERKINS
THE POST–PROCESSING REVOLUTION wrought by the introduction of Photoshop in 1988 has so profoundly influenced the act of picture-making that many shooters think of the program as half of a complete two-step process of photography. In Step One, you shoot the image. In Step Two, you fix it.
However, being conversant with more of the menu options built in to nearly every level of camera in use today can mean solving most “post” dilemmas without resorting to Photoshop’s full suite of solutions. Just as you change lenses less the more you understand what lenses can be stretched to achieve, you can avoid the extra step of computer-based tweaking the more you understand what’s already available while your subject, your shooting conditions and your mental presence are all in play. Some would argue that such adjustments would be more finely attenuated working with a RAW file in Photoshop than by fixing flaws in-camera with a JPEG, and you have to decide where you come down in that debate.
Let’s take color as one example. A great many photographs with off-kilter values are corrected in Photoshoppish apps, yet can be quite satisfactorily fixed in-camera. White balance settings allow you to pre-program a number of light temperature pre-sets that make your camera “see” colors as if they are occurring in sunshine, shade, or a variety of artificial light sources. But even if you shoot everything on the “auto” white balance setting and get the wrong colors occasionally, there is still a way to repair the damage without resorting to Photoshop. What Nikon and Canon both call color balance allows fairly fine-tuned adjustments to get the hues to look either (a) more like you saw it, or (b) the way you wish it had looked.
The shot at top, adjusted with Nikon’s color balance option, produced the warmer look in the bookshelves that would have resulted if the light coming through the window had been warmer. In the original image, taken with an auto white balance setting, the camera, far from “guessing wrong”, actually recorded the room light as it appeared in reality, since the sky was severely cloudy and was a little blue in cast. However, with the in-camera color balance tweak, no Photoshop intervention was required. Moreover, I could check my work while in the moment, a handy thing, since tours were moving in and out of the room all day, meaning that, if I wanted to shoot the room (nearly) empty, I had to work fast.
Digital photography’s original bragging point over film was the ability to shoot, fix, and shoot again rather than rely on the darkroom to rescue tragically few of our miscalculations. Working our in-camera menus for all they’re worth helps deliver on that promise.
