Self-portrait photography presents an elucidatory range of cases for investigating the relationship between automatism and artistic agency in photography-a relationship that is seen as a problem in the philosophy of art. I discuss self-portraits by photographers who examine and portray their own identities as artists working in the medium of photography. I argue that the automatism inherent in the production of a photograph has made it possible for artists to extend the tradition of self-portraiture in a way that is radically different from previous visual arts.In Section I, I explain why self-portraiture offers a way to address the apparent conflict between automatism and agency that is debated in the philosophy of art. In Section II, I explain why mirrors play an important function in the production of a traditional self-portrait. In Sections III and IV, I discuss how photographers may create self-portraits with and without the use of mirrors to show how photography offers unique and important new forms of self-portraiture.
