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.

"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 almost every photograph I have ever made, there is something I would do to complete it. I take that to be the spirit hole or the deliberate mistake that's in a Navajo rug to not be godlike, but to be human.

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.

I did it once, and National Geographic recruited me. I did it primarily out of curiosity. A lot of legendary photographers had worked on that campaign. Ernst Haas had done the early photography, and I knew him. There's a lore in photography about that campaign, and I was curious.

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.

My father taught me photography. It was his hobby, and we had a small darkroom in the fruit cellar of our basement. It was the kind of makeshift darkroom that was only dark at night.
