Can a photograph change the world?

Photograph by Lewis W. Hine of a small spinner at Mollohan Mills, Newberry, S.C.: "She was tending her 'sides' like a veteran, but after I took the photo, the overseer came up and said in an apologetic tone that was pathetic, 'She just happened in.' Then a moment later he repeated the information. The mills appear to be full of youngsters that 'just happened in,' or 'are helping sister.' National Child Labor Committee/Library of Congress

“Photography is a small voice, at best, but sometimes one photograph, or a group of them, can lure our sense of awareness.”

(W. Eugene Smith, Paris: Photopoche)
