Increasingly, it's people not interested in National Geographic.

For example, in my dorm, at the University of Kentucky, I had the only camera. I don't think anyone came to college with a camera, other than me.

We know that photographs inform people. We also know that photographs move people. The photograph that does both is the one we want to see and make.

I did it once, and National Geographic recruited me. I did it primarily out of curiosity. A lot of legendary photographers had worked on that campaign. Ernst Haas had done the early photography, and I knew him. There's a lore in photography about that campaign, and I was curious.

[ My time and our common culture] it's what I'm photographing, and I'm very involved with that.

I can't speak for other photographers, but the photographers who went forward strongly when the so-called "official" part of their career ended, to me, were those who had taught. Teaching enriches and enlivens one's work.

The best lesson I was given is that all of life teaches, especially if we have that expectation.
