The decision as to when to photograph, the actual click of the shutter, is partly controlled from the outside, by the flow of life, but it also comes from the mind and the heart of the artist. The photograph is his vision of the world and expresses, however subtly, his values and convictions.

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.

Photography is only a new road from a different direction, but moving toward the common goal, which is life.

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)

All light is available light.

No matter what lens you use, no matter what speed the film, no matter how you develop it, no matter how you print it, you cannot say more than you can see.

The camera machine cannot evade the objects which are in front of it. When the photographer selects this movement, the light, the objects, he must be true to them. If he includes in his space a strip of grass, it must be felt as the living differentiated thing it is and so recorded. It must take its proper but no less important place as a shape and a texture in relationship to the mountain tree or what not, which are included.
