Everything went together perfectly, and this is what I mean by knowing. I didn't have to analyze anything. I just recognized what was in front of me. All I had to do was set up and take the picture.

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.

A person is quite different from a tree or rock or stream. By introducing the nude into my pictures, I started perceiving all the things I was photographing in new ways. In contrast or opposition to each other, things became much more significant and interesting, revealing many more qualities than I had ever dreamed of knowing and expressing. By using the nude, I stopped thinking in terms of objects.

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.

What you see is real - but only on the particular level to which you've developed your sense of seeing. You can expand your reality by developing new ways of perceiving.

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.
