The opposition between original and mechanically reproduced works of art only gets Walter Benjamin so far, and it often leads The Work of Art in an Age of Mechanical Reproduction into contradiction and confusion. The intended targets of mechanical reproduction are photography and film, yet from the outset, the attempt to exclude painting from being another form of mechanical reproduction is in difficulty. The example ' a cathedral leaves its site to be received in the studio of an art lover ' is intended to be about photography, but clearly, could be about painting too, were it not for the additional criteria of tradition, authenticity, and aura, which Benjamin attaches as characteristics to a painted reproduction but not to a photographic reproduction.
