Every artist I suppose has a sense of what they think has been the importance of their work. But to ask them to define it is not really a fair question. My real answer would be, the answer is on the wall.

Objectivity is of the very essence of photography, its contribution and at the same time its limitation

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

All light is available light.

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

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.

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.
