What I'm interested in is modern American history. I'm taken with the changes that have occurred in America in my lifetime.

...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.

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.

There are a lot of ways to be expressive in life, but I wasn't good at some of them. Music, for instance. I was a distinct failure with the cello. Eventually, my parents sold the cello and bought a vacuum cleaner. The sound in our home improved.

I wanted life to be episodic. I wanted to be a magazine photographer and I was willing to do what it took to become that.

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.

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.
