Question: Who is the photographer associated with the New York School of Photography whose used his camera as a tool for social reform.
Sentence (from "New York school of photography"): Livingston writes that their work was marked by humanism, a tough-minded style, photojournalistic techniques, the influence of "film noir" and the photographers Lewis Hine, Walker Evans, and Henri Cartier-Bresson; and that it avoided "the anecdotal descriptiveness of most photojournalism" and the egoism of American action painting, and indeed that it was remarkably little influenced by contemporary painting or graphic design (even though a number of its exponents had direct experience of these).
Relevant evidence: Yes
