Abstract
Philosophy's only celebration of photography's 150th, the long-neglected philosophical job of clarification: drawing basic distinctions and defining basic conceptions, including photographic depiction, photographic detection, 'photograph of', 'documentary'. More than a lexicon, it explains why photography is important, by historically characterizing it through its uses for depiction, detection, reproduction, all of which have shaped the modern world. By consideration of it as 'mechanical', the paper explains photography's differences from practices with which it shares these functions. Happy birthday, photography.
