Editorial photography has to be energetic and visually competitive.

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.

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.

The reason I don't want to say anything about it is it has a strange power to take over the conversation. Just like it's doing with us. I was asked to participate in a documentary about Richard Prince, and be the voice of someone who was appropriated, and I declined. The reason I did is I don't want it to be the subject of the discussion of my work.

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.

The neatest part of this book I'm working on - to me - are the pictures that show the process... Because photographers... think things through and... it isn't luck, and it isn't random and it isn't accidental. It isn't.

It's a little bit like talking about the life of writing. The life of writing may be about many things, but it always begins with the writer. With the kernel of an idea, or a character, or an idea or a theme, or even an outcome. But for documentary photographers, photographs begin at that intersection of the real world and the imaginative inner world.
