In my opinion, as soon as someone comes up with a single firm and true definition of "Art" perhaps that question can be answered correctly. Some people do think photography is an art form, some don't. I personally feel that photography doesn't have to be art but it can be if the photographer, or the person viewing the photograph, so desires. Is a photograph of a smiling child or a cat sleeping in a window art? Maybe and then again maybe not. It just depends on how it is interpreted and what the particular person's definition of "Art" happens to be.
