Garbage in, garbage out

True story: I once saw a guy taking 10-second exposures of the moonbow at the base of Yosemite Falls, hand-held. When I gently suggested that his image might be a little soft, he assured me that he would just sharpen it in Photoshop. I won’t deny that digital capture and processing has given photographers more flexibility and control than ever, and processing can indeed correct…

So smart, in fact, that for most scenes, getting the exposure right is a simple matter of pointing your camera and clicking the shutter button. That’s fine if all you care about is recording a memory, but not only is there more to your exposure decision than getting the amount…

Soon our footsteps were in sync, each tap broken by a beat of eerie silence….

Managing light, depth, and motion in nature

Independent of composition, photographers have three scene variables to play with when setting up a shot: light, depth, and motion. And not so coincidentally, we have three exposure parameters with which to manage those variables: shutter speed, f-stop, and ISO. The exposure parameters have a reciprocal relationship—an increase/decrease in one can be compensated by a corresponding decrease/increase in another—but merely getting the “correct” exposure with a…
