NEW YORK - The advent of the Polaroid Big Shot camera in 1971, with its instant delivery of a finished print, was an ideal tool for Andy Warhol; he could tote the camera to parties, photographing celebrities, socialites and friends alike, and similarly keep several (priced at the reasonable cost of $19.95) at The Factory to use for “formal” portrait sittings. While Warhol had mechanized the production of his works by the use of assistants in The Factory, the Polaroids present a uniquely intimate portrayal of Warhol – both behind and in front of the camera.
