I love the medium of photography, for with its unique realism it gives me the power to go beyond conventional ways of seeing and understanding and say, This is real, too.

Whenever I have found myself stuck in the ways I relate to things, I return to nature. It is my principal teacher, and I try to open my whole being to what it has to say.

Theoretical scientists who probe the secrets of the universe and philosophers who seek answers to existence, as well as painters such as Paul Klee who find the thoughts of men of science compatible with art, influence me far more than most photographers.

As sounds in a musical composition can be used not to express physical objects but ideas, emotions, harmonies, rhythmic orders and most any expression of the human mind and spirit, so light can be used visually to express the mind and spirit.

The camera is not only an extension of the eye but of the brain. It can see sharper, farther, nearer, slower, faster than the eye. It can see by invisible light. It can see in the past, present, and future. Instead of using the camera only to reproduce objects, I wanted to use it to make what is invisible to the eye - visible.

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.

What I feel is that the picture-taking process, anyway a greater part of it, is an intuitive thing. You can't go out and logically plan a picture, but when you come back, reason then takes over and verifies or rejects whatever you've done. So that's why I say that reason and intuition are not in conflict-they strengthen each other.
