The best writing on photography has been by moralists—Marxists or would-be Marxists—hooked on photographs but troubled by the way photography inexorably beautifies. As Walter Benjamin observed in 1934, in an address delivered in Paris at the Institute for the Study of Fascism, the camera is now incapable of photographing a tenement or a rubbish-heap without transfiguring it. Not to mention a river dam or an electric cable factory: in front of these, photography can only say, ‘How beautiful.’ … It has succeeded in turning abject poverty itself, by handling it in a modish, technically perfect way, into an object of enjoyment.
Moralists who love photographs always hope that words will save the picture.
— Susan Sontag, On Photography, 1977
