For the Streetwork series, diCorcia developed a technique to photograph passers-by unawares. He set up an unobtrusive system of lights that could be activated by radio-signal. When a suitable subject walked past, diCorcia could take a candid snapshot whose elaborate lighting (in the artists words) adds a cinematic gloss to a commonplace event. The resulting photographs project a sense of the solitude and introspection within the bustle of the city.
DiCorcia has commented:
the street does not induce people to shed their self-awareness. They seem to withdraw into themselves. They become less aware of their surroundings, seemingly lost in themselves.
