A photographer’s eye is perpetually evaluating. A photographer can bring coincidence of line simply by moving his head a fraction of a millimeter. He can modify perspectives by a slight bending of the knees. By placing the camera closer to or farther from the subject, he draws a detail. But he composes a picture in very nearly the same amount of time it takes to click the shutter, at the speed of a reflex action. — Henri Cartier-Bresson
