When I first went to 'National Geographic,' I thought I was the least qualified person to step through the doors. But because of my parents and the culture of continual learning they imposed on us, I later came to believe I was the most qualified person who ever worked there.

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.

My first priority when taking pictures is to achieve clarity. A good documentary photograph transmits the information of the situation with the utmost fidelity; achieving it means understanding the nuances of lighting and composition, and also remembering to keep the lenses clean and the cameras steady.

"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."

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.

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.

I was known as a 35-mm photographer with a view-camera mentality.
