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.

The unusual wins out over the usual.

"You know you are seeing such a photograph if you say to yourself, "I could have taken that picture. I've seen such a scene before, but never like that." It is the kind of photography that relies for its strengths not on special equipment or effects but on the intensity of the photographer's seeing. It is the kind of photography in which the raw materials-light, space, and shape-are arranged in a meaningful and even universal way that gives grace to ordinary objects."

In the last workshop I taught, a woman flew in from Thailand. She's a medical doctor in Bangkok. I asked her in her one-on-one session where she wanted photography to be in her life.Did she want a second career? Was it about earning money? Or was it art? And she said "None of those. I want photography to be serious in my life." It would be like someone wanting music, like piano playing, to be a richer, deeper, and maybe even harder experience.

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.

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.

I think that it's workshops, honestly, that have kept me keen about photography, and about my photography. My career as a workshop photographer came while I was at the Geographic in the late 70's, and has continued consistently since then.
