When I'm about ready to press the cable release on the View camera, I've tried to anticipate some of the challenges I'm going to encounter in the darkroom.

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.

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. "
