Though Geographic didn't publish that photo in the story that it was done for, "The Life of Charlie Russell," a cowboy artist in Montana. But later, maybe a year and a half ago, they named it one of the 50 greatest pictures ever made at National Geographic.

It actually has transcended my career at the Geographic, so that when my career there ended, I had momentum as a teacher, and a belief in photographic education at the workshop level.

Above all, it's hard learning to live with vivid mental images of scenes I cared for and failed to photograph. It is the edgy existence within me of these unmade images that is the only assurance that the best photographs are yet to be made.

A very big part of the life of a photograph is the afterlife.

How the visual world appears is important to me. I'm always aware of the light. I'm always aware of what I would call the 'deep composition.' Photography in the field is a process of creation, of thought and technique. But ultimately, it's an act of imaginatively seeing from within yourself.

I'm very involved in photographing America now, so I don't think of faraway places, as I did when I was young.

In my first class at the University of Kentucky, my American Literature professor came in, and the first sentence out of his mouth was "The central theme of American Literature is an attempt to reconcile what we've done to the New World." wrote that down in my notebook, and thought, "What is he talking about?" But that's what I think about now. The New World and what we've done to it.
