the habit of photographic seeing—of looking at reality as an array of potential photographs—creates estrangement from, rather than union with, nature.Photographic seeing, when one examines its claims, turns out to be mainly the practice of a kind of dissociative seeing, a subjective habit which is reinforced by the objective discrepancies between the way that the camera and the human eye focus and judge perspective. These discrepancies were much remarked by the public in the early days of picture-taking. Once they began to think photographically, people stopped talking about photographic distortion, as it was called. (Now, as William Ivins, Jr., has pointed out, they actually hunt for that distortion.) Thus, one of the perennial successes of photography has been its strategy of turning living beings into things, things into living beings. The peppers Weston photographed in 1929 and 1930 are voluptuous in a way that his female nudes rarely are. Both the nudes and the pepper are photographed for the play of forms—but the body is characteristically shown bent over upon itself, all the extremities cropped, with the flesh rendered as opaque as normal lighting and focus allow, thus decreasing its sensuality and heightening the abstractness of the body’s form; the pepper is viewed close-up but in its entirety, the skin polished or oiled, and the result is a discovery of the erotic suggestiveness of an ostensibly neutral form, a heightening of its seeming palpability.
