There is nothing mysterious about space-time. Every speck of matter, every idea, is a space-time event. We cannot experience anything or conceive of anything that exists outside of space-time. Just as experience precedes all awareness and creative expression, the visual language of our photographs should ever more strongly express the fourth dimensional structure of the real world.

Human beings to me are as much a part of nature as trees or birds, and the unclothed body expresses this belongingness directly and powerfully.

I didn't want to tell the tree or weed what it was. I wanted it to tell me something and through me express its meaning in nature.

For me photography has been a profession, an avocation. Now it has become a way of life.

If you stop searching, you stop living, because then you're dwelling in the past. If you're not reaching forward to any growth or future, you might as well be dead.

In a photograph, if I am able to evoke not alone a feeling of the reality of the surface physical world but also a feeling of the reality of existence that lies mysteriously and invisibly beneath its surface, I feel I have succeeded. At their best, photographs as symbols not only serve to help illuminate some of the darkness of the unknown, they also serve to lessen the fears that too often accompany the journeys from the known to the unknown.

Light to me is perhaps the most profound truth in the universe. My thinking has been deeply affected by the belief everything is some form of radiant energy.
