'Someone Else's' is an ongoing series of 'found photo' books. I often buy 35mm cameras from charity shops if they contain film, then have the film processed. If there are enough images to create a book or narrative, I do. Authorship and the role of photography are obvious questions. I don't know whether the photographer is alive or dead, or who they were. The books are part of Tate Gallery collections and Leeds University Special Collection.
