“New Topographics: Photographs of a Man-Altered Landscape” was an exhibition that epitomized a key moment in American landscape photography. The show was curated by William Jenkins at the International Museum of Photography at the George Eastman House (Rochester, New York), and remained open to the public from October 1975 until February 1976.
