For most of the nineteenth century, a working photographer who called their work art would have faced polite condescension from painters and critics alike, on the argument that a camera merely records what is placed in front of it, while a painter invents. The Pictorialist movement, active from the 1880s through the early twentieth century, answered that argument by making photographs that looked as much like paintings as the chemistry allowed, using soft focus, elaborate hand printing techniques such as gum bichromate, and painterly, allegorical subject matter, precisely so that a photograph could be judged by the standards already applied to painting rather than argue for new ones. Alfred Stieglitz, the movement's most influential American champion, eventually reversed course, and his Photo-Secession group came to argue instead for straight photography, images that looked unmistakably photographic and asked to be judged as their own medium rather than an imitation of an older one. That argument won within photographic circles well before it won in museums. The Museum of Modern Art in New York, now home to one of the world's most important photography collections, did not establish a dedicated photography department until 1940, a full century after the medium's public debut, and many encyclopedic art history surveys continued to treat photography as an appendix to painting and sculpture rather than a coequal subject well into the postwar period. It is worth asking what the debate was actually about, because the technical case against photography as art, that it merely records rather than invents, does not survive contact with what a photographer actually does: choosing a frame, a moment, a light, a print process, decisions as consequential and as unrepeatable as a painter's brushstroke. The more honest reading is that painting's claimed uniqueness, its exclusive hold on the category of serious visual art, was genuinely threatened by a mechanical medium that could produce a convincing likeness in a fraction of the time, and the debate over photography's artistic legitimacy was, underneath its aesthetic vocabulary, a debate about who got to keep that hold.
