None. They should just go out and photograph and stop talking about it. That's the only way they are going to find themselves. They can't do it in their heads - they have to go out and do it in the camera and get it on film.

Some people are still unaware that reality contains unparalleled beauties. The fantastic and unexpected, the ever-changing and renewing is nowhere so exemplified as in real life itself.

I'm not a nice girl; I'm a photographer. (On being told by a Federal Art Project official, after she photographed the Bowery, that a nice girl should not go into such neighborhoods )

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, more selective, more acute eye by looking ever more sharply at what is going on in the world. Like every other means of expression, photography, if it is to be utterly honest and direct, should be related to the life of the times-the pulse of today. The photograph may be presented as finely and artistically as you will, but to merit serious consideration, must be directly connected with the world we live in.

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

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.

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.
