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.

When assignments were over, photography continued. One of the primary reasons it did was that I wanted and needed to have fresh work. Also, it's very stimulating to be around non-professional photographers. They're the ones with the purest flame burning about their photography. I appreciate that.

That statement [ Stephen Ambrose:'You, Sam, have the hardest job, which is, pretend like nothing has happened in the last 200 years.'] woke me up to the fact that the landscape that Lewis and Clark came across was greater than the Serengeti. And it's gone.

I will just say, appropriation is an intellectual idea until it happens to you. It's a philosophy, and it's got its own intellectual framework. Then there's what happens when it's your photograph. Then it's personal, and that's all I'll say.

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.

I was a consultant for Kodak back in the late 80's. There were engineers there who told me that in the future, most photographs would be taken on telephones. They weren't able to do anything with that. They were engineers, not management.

There are a lot of ways to talk about the life of a photograph. You can talk about the afterlife of a photograph, and in the end I talk about that, with the Richard Prince picture. But mainly, what I dedicated the book to being about was how photographs begin their life, and where they begin it. And they begin it with the photographer's imagination and instinct and experience.
