I say to young photographers, 'What in God's name are you doing, taking a picture of a tree or a mountain? That's crazy! What you should do is take a person by the hand and show him the tree or the mountain itself. Why show him a stupid picture? It's flat and it's tiny compared to the mountain. The mountain is magnificent and has power . . .' They look at me as if I'm nuts. They don't know what to say back to me. So I go on to say that the reason you show someone a photograph is because a photograph is part of a human being--you--and as people we're more interested in human beings than we are in mountains. By showing a picture, you're showing an x-ray of your heart. The very silent, marvelous American painter, Edward Hopper, put it very simply. He said, 'The work's the man. You can't get something out of nothing.'
