Even though I teach with 35mm, my method takes people by surprise, because it isn't fast, and it isn't about hardware or software, or even great results. It's about great process.

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

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.

My least favorite photographer to have would be myself. Someone who wanted a career at National Geographic. Because it's almost mathematically impossible to achieve that.

The thing with my workshops is, photography is a thoughtful process. In an atmosphere of fast photography, and generally thoughtless, quick, automatic photography, I think that there is an interest in the slowed down, thoughtful approach.

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 started teaching in '76 and I'd been a photographer at the Geographic for six years. But prior to being at the Geographic I was a teacher. Plus my parents were teachers and my brother and my grandparents. So it was the culture of our family to think about teaching, to talk about teaching, to talk about teachers.
