Assuming you think that photography can fall into the fine art category, can photography that has been Photoshopped be fine art? There have always been darkroom techniques that let you fiddle with the image some, but I was always under the impression that to be considered fine art, the photo could stand alone, sans manipulation.
According to the exhibit I saw Friday, not so. From photography's inception images have been tinkered with. Take Gustave Le Gray. Above is one of his images. He was famous for taking the same shot twice; once to get the subtleties of the ocean, and once to capture the sky. He would then cut the negative and combine the best of each picture to get one great photo.
