Rothstein, Lange and Evans have been accused of posing their photographs, in short, of manipulating them to some end. And yet all photographs are posed. There is no such thing as pure documentary photography. The problem is not in what any of them have done, but in our misunderstanding of photography. No crimes were committed by the F.S.A. photographers. They labored as employees of an organization dedicated to providing propaganda for the Roosevelt administration. And they created some of the greatest photographs in American history. Photographs can be works of art, bearers of evidence, and a connection with the past for individuals, families and society as a whole.
