The photographer’s act is to see the outside world precisely, with intelligence as well as sensuous insight. This act of seeing sharpens the eye to an unprecedented acuteness. He often sees swiftly an entire scene that most people would pass unnoticed. His vision is objective, primarily. His focus is on the world, the scene, the subject, the detail. As he scans his subject he sees as the lens sees, which differs from human vision. Simultaneously he sees the end result, which is to say he sees photographically.
