Photographer Roy David Colmer (born 1935) is perhaps most well known for the "snapshot aesthetic" conveyed by his seminal photographic project, Doors, NYC (1976). Colmer (who was born in Britain) received his artistic training at the Hochschule für Bildende Künste in Hamburg and immigrated to New York in 1967. He worked first as a painter before turning to film and photography in the 1970s. In 1982, he studied photography with Lisette Model at the New School, where he later taught. He received a Guggenheim Fellowship in 1988 and a grant from the Foundation for Contemporary Performance Arts, Inc., in 1990. In 1976, Colmer completed Doors, NYC, which includes more than 3,000 images of doors taken in sequence on 120 intersections and streets of Manhattan, from Wall Street to Fort Washington. Portions of the work were later exhibited at PS 1 in Long Island City, Queens, and incorporated and shown in Hanne Darboven's work, Kulturgeschichte 1880-1983 (Cultural History 1880-1983), 1980-83.
