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.

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.

I have this awareness that the more dynamic the situation is, the more on guard I need to be that the dynamic isn't controlling the situation. I found that myself in the Galapagos. For the first time in my life I was around very exotic animals, colorful, beautiful, and immediately present, all around. Birds, turtles, iguanas, seals. I was being seduced by their exoticism, I was taking pictures.The pictures weren't well lit, there was no moment in play, there was no depth to the pictures. I was just gawking with my camera at something I'd never seen before.

There isn't an aspect of book creation I don't enjoy, and there has always been a book in my life to dream about or work on.

Teaching has never been far from my life. It's the most natural thing I do. Apparently, as I said, I cannot not do it.

One of the things that I most believe in is the compose and wait philosophy of photography. It’s a very satisfying, almost spiritual way to photograph. Life isn't’ knocking you around, life isn't controlling you. You have picked your place, you’ve picked your scene, you’ve picked your light, you’ve done all the decision making and you are waiting for the moment to come to you.

Photography, alone of the arts, seems perfected to serve the desire humans have for a moment - this very moment - to stay.
