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.

I was giving a lecture and I said, that's enough about The Photographic Life, meaning my biography, now let's talk about the life of a photograph. And in that one instant I got the title for a potential next book.

For spiritual companions I have had the many artists who have relied on nature to help shape their imagination. And their most elaborate equipment was a deep reverence for the world through which they passed. Photographers share something with these artists. We seek only to see and to describe with our own voices, and, though we are seldom heard as soloists, we cannot photograph the world in any other way.

For sheer majestic geography and sublime scale, nothing beats Alaska and the Yukon. For culture, Japan. And for all-around affection, Australia.

First of all, I appropriate photographs.In presenting the Richard Prince photograph I tried to be as neutral as I could be. I put down the fact of it. I wanted it to be the same thing he wanted it to be, an open ended invitation to think about authorship, and who owns a created work. So I pair it with my appropriated picture.

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

There are things that I teach, about building photographs, and that's why people come to my workshops. When people come to the workshops, they're consumed with seeking the subject, and I teach seeking the setting.
