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 was asked by a student what my most significant accomplishment was at National Geographic, after thirty years, and I said that my career came to an appropriate close, and I still loved photography. Not everybody who spends their career at anything ends up fascinated and involved with it.

It's more difficult now, to be a Geographic photographer, than it was when I came along. And it wasn't easy at that time.

In my first class at the University of Kentucky, my American Literature professor came in, and the first sentence out of his mouth was "The central theme of American Literature is an attempt to reconcile what we've done to the New World." wrote that down in my notebook, and thought, "What is he talking about?" But that's what I think about now. The New World and what we've done to it.

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.

...just like some people's instinct to photograph is triggered by vacation... assignments might be that to me and that's why I've built my life around assignments. That was the way to live the photographic life.

Above all, it's hard learning to live with vivid mental images of scenes I cared for and failed to photograph. It is the edgy existence within me of these unmade images that is the only assurance that the best photographs are yet to be made.
