Not showing up in photos would really suck because you wouldn't have any pictures of yourself, and you wouldn't be able to have an album of memories. If you didn't show up in mirrors, however, you could just rig up a camera and TV instead. The main drawback there would be that it would be easier for people to notice you not being in mirrors and freak out. It would be fairly easy to avoid having your photo taken by someone who would notice you missing.
