The endless fascination of these people for me lies in what I call their inward power. It is part of the elusive secret that hides in everyone, and it has been my life's work to try to capture it on film. The mask we present to others and, too often, to ourselves may lift for only a second – to reveal that power in an unconscious gesture, a raised brow, a surprised response, a moment of repose. This is the moment to record. Within every man and woman a secret is hidden, and as a photographer it is my task to reveal it if I can.
