All light is available light.

To be a photographer you must have something to say about the world.

The important thing is, you have to have something important to say about the world.

Whether a watercolor is inferior to an oil [painting], or whether a drawing, an etching, or a photograph is not as important as either, is inconsequent. To have to despise something in order to respect something else is a sign of impotence.

The artist's world is limitless. It can be found anywhere, far from where he lives or a few feet away. It is always on his doorstep.

I don't care how you photograph - use the kitchen mop if you must, but if the product is not true to the laws of photography... you have produced something that is dead. (1923)

The documentary photographer aims his camera at the real world to record truthfulness. At the same time, he must strive for form, to devise effective ways of organizing and using the material. For content and form are interrelated. The problems presented by content and form must be so developed that the result is fundimentally [sic] true to the realities of life as we know it. The chief problem is to find a form that adequately represents the reality.
