Timing is everything. Every photographer knows that and wrestles with that very constraint. It’s one thing to know it and entirely another thing to be able to anticipate it, recognize the moment when it arrives, and react to it before it’s over. What cripples us a little, I think, is that we’re taught quite early to pay a great deal of attention to the length of the moment we capture (is it 10 seconds, 1/10 of a second, or 1/1000 of a second?) but less on which moment we capture. And moments, at least in the eye of the camera, are not all created equal.
