If a medium is representational by nature of the realistic image formed by a lens, I see no reason why we should stand on our heads to distort that function. On the contrary, we should take hold of that very quality, make use of it, and explore it to the fullest.

The lens freezes time and space in what may be an optical slavery or, contrarily, the crystallization of meaning. The limits of the lens' vision are esthetically often a virtue.

Pictures are wasted unless the motive power which impelled you to action is strong and stirring.

I wanted to combine science and photography in a sensible, unemotional way. Some people’s ideas of scientific photography is just arty design, something pretty. That was not the idea. The idea was to interpret science sensibly, with good proportion, good balance and good lighting, so we could understand it.

Photography helps people to see.

To chart a course, one must have a direction. In reality, the eye is no better than the philosophy behind it. The photographer creates, evolves a better, a more selective, more acute seeing eye by looking ever more sharply at what is going on in the world.

I have yet to see a fine photograph which is not a good document.
