It had rained on some vivid green ferns in Maine and it was quite beautiful. I was moving the camera slightly and studying the ground glass. Looking at those 20 square inches, trying to find out just what were the right elements to include.

Pictures you have taken have an influence on those that you are going to make. That's life!

I remembered seeing it and it was this metallic turbine and I thought it was beautiful. I had never been in a power plant before, but I felt, without being overly dramatic, compelled to make photographs of this for myself.

The greatest compliment that I know how to pay another photographer is to say, 'I never would have made that photograph myself. I'm sure glad you did.' You hope along the way that maybe, once in a while, you do that for someone else.

Whatever it takes to get the image to reach that level is what that photographer needs to do. And for me, I just have such a love of the tactile and sensuous quality of a black and white silver gelatin print.

I took a workshop from him a few months after that. That experience changed my whole approach to photography. At that workshop in Yosemite in 1973 I decided I wanted to try and see if I could pursue this for myself, and I'm still trying.

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.
