Christopher Isherwood's short story "Sally Bowles" and the four dramatic and cinematic adaptations of that text provide a useful illustration of the fluid nature of the Camp aesthetic, as the sensibility shared by the narrator and Sally Bowles incrementally vanishes from their counterparts in the adaptations, while the films and plays themselves become objects imbued with the quality of camp. In her article "Notes on Camp," Susan Sontag distinguished between Camp as a sensibility possessed by individuals and Camp as an attribute perceived. The distinction between Camp as a sensibility and Camp as the quality revealed to one with that sensibility has often been blurred; in the transition from novel to stage play to film, the Camp nature of characters and situations shifts as the narrative position is altered.
