As a self-confessed “professional watcher”, Elliott Erwitt is particularly adept at reading body-language. This unfiltered exchange— sometimes overt, at other times so slight that the participants themselves may be blissfully unaware—is magnified tenfold under Erwitt’s gaze. But it is the subtlety that draws him closer; a raised eyebrow, a tilt of the head, the lifting of a veil. “When a woman and man are together, the slightest suggestion of movement or angle weaves a whole tapestry of implications,” he says. Erwitt’s precise observation of the human condition offers both blink-and-you-miss-it moments and scenes still developing. Both are particularly fruitful when applied to the subject of love.
