Like all photographers, I depend on serendipity, and when you're photographing children there's often an abundance of it. I would have an idea of what a photograph would look like and then something would happen - a dog might lumber in and become a critical element. I pray for what might be referred to as the angel of chance.

I have nothing but respect for people who travel the world to make art and put exotic Indians in front of linen backdrops, but it's always been my philosophy to try to make art out of the everyday and ordinary.

Some of my pictures are poem-like in the sense that they are very condensed, haiku-lik. There are others that, if they were poetry, would be more like Ezra Pound. There is a lot of information in most of my pictures, but not the kind of information you see in documentary photography. There is emotional information in my photographs.

The fact is that these are not my children; they are figures on silvery paper slivered out of time. They represent my children at a fraction of a second on one particular afternoon with infinite variables of light, expression, posture, muscle tension, mood, wind and shade. These are not my children at all; these are children in a photograph.

Photographs supplant and corrupt the past, all the while creating their own memories.

All the good pictures that came so easily now make the next set of pictures virtually impossible in your mind.

There's always a time in any series of work where you get to a certain point and your work is going steadily and each picture is better than the next, and then you sort of level off and that's when you realize that it's not that each picture is better then the next, it's that each picture up's the ante. And that every time you take one good picture, the next one has got to be better.
