Philip-Lorca diCorcia, Head #10, 2001
A more recent approach to photographing strangers without permission – albeit a rather less surreptitious one – is that taken by Philip-Lorca diCorcia for his series Heads. This series was made in Times Square, one of the busiest places in New York City and a place where bright lights and tourist cameras go with the territory. DiCorcia rigged up lights, using portable flash synced to his camera which was focused on the area he was lighting, and stood twenty feet or so away with a telephoto lens on his camera. When someone he wanted to photograph came into his zone of light and focus he pressed the shutter and recorded the head of his subject. Simple.
