In my mind I needed a symbol of today's technology, and I realized that what I wanted to photograph was the Space Shuttle. And so that's where Places of Power came into being.

In 1979, I received a phone call from Ansel Adams asking me if I would be willing to consider coming to work for him. I was teaching photography in Southern California at that point.

"It is light that reveals, light that obscures, light that communicates. It is light I "listen" to. The light late in the day has a distinct quality, as it fades toward the darkness of evening. After sunset there is a gentle leaving of the light, the air begins to still, and a quiet descends. I see magic in the quiet light of dusk. I feel quiet, yet intense energy in the natural elements of our habitat. A sense of magic prevails. A sense of mystery. It is a time for contemplation, for listening - a time for making photographs. "

It was an experience that was exceptional. People frequently ask what it was like and it truly was inspiring. Sometimes during his lifetime, people would try and put him on a pedestal and that's not where he wanted to be, but he was really a great individual.

I've found even after nearly 30 years of doing this, there are all kinds of new surprises that rear their heads at various times and I truly believe that 51% of the images, success takes place in the darkroom.

Obviously, we can see what was in front of the camera, but if a photograph is honestly made, it's a bit of a self-portrait. I think it's impossible for a photographer who is working honestly to keep this from happening.

We all start in this medium because of the magic and the challenge is to keep it going.
