"With the camera, it's all or nothing. You either get what you're after at once, or what you do has to be worthless. I don't think the essence of photography has the hand in it so much. The essence is done very quietly with a flash of the mind, and with a machine. I think too that photography is editing, editing after the taking. After knowing what to take, you have to do the editing."

-- Walker Evans, 1971
