If it's a likeness, alone, it's not a success. If, through my portraits, you can come to know the subjects more meaningfully, if it synthesizes your feelings toward someone whose work has imprinted itself on your mind--if you see a photograph and say, 'Yes, this is the person,' with a little new insight--that is a beautiful experience.
The revelation, if it comes at all, will come in a small fraction of a second with an unconscious gesture, a gleam of the eye, a brief lifting of the mask that all humans wear to conceal their innermost selves from the world. In that fleeting interval of opportunity the photographer must act or lose his prize.
