From Wikipedia
Walker Evans was an American photographer and photojournalist best known for his work for the Resettlement Administration and the Farm Security Administration (FSA), for whom he documented the effects of the Great Depression. Evans published his first photos at the age of 27. The majority of Evans' New Deal photography made use of the large format, 8 × 10-inch (200×250 mm) view camera. Evans claimed that his goal as a photographer was to make pictures that are "literate, authoritative, transcendent".
