Moving Pictures

From Susan Sontag, On Photography:

Photographs furnish evidence. Something we hear about, but doubt, seems proven when we’re shown a photograph of it. In one version of its utility, the camera record incriminates. Starting with their use by the Paris police in the murderous roundup of Communards in June 1871, photographs became a useful tool of modern states in the surveillance and control of their increasingly mobile populations. In another version of its utility, the camera record justifies. A photograph passes for incontrovertible proof that a given thing happened. The picture may distort; but there is always a presumption that something exists, or did exist, which is like what’s in the picture.” (p. 3)
