All light is available light.

If you let other people's vision get between the world and your own, you will achieve that extremely common and worthless thing, a pictorial photograph.

Look at the things around you, the immediate world around you. If you are alive, it will mean something to you, and if you care enough about photography, and if you know how to use it, you will want to photograph that meaningness. If you let other people's vision get between the world and your own, you will achieve that extremely common and worthless thing, a pictorial photograph.

The portrait of a person is one of the most difficult things to do. It means you must almost bring the presence of that person photographed to other people in such a way that they don't have to know that person personally, but that they are still confronted with a human being that they won't forget. That's a portrait.

Photography... is either an expression of a cosmic vision, an embodiment of a life movement or it is nothing - to me. (1919)

If the photographer is not a discoverer, then he is not an artist.

The artist is one who makes a concentrated statement about the world in which he lives and that statement tends to become impersonal-it tends to become universal and enduring because it comes out of something very particular.
