An idea. I read somewhere that someone to motivate themselves would take two rolls of film . . . into their privy. Take a whole roll of images that show that they are in the bathroom and then expose the second roll with the idea in mind to remove any indication the you are in the john. That would be the challenge. To take such a small room and make 50 good images, 25 indicating your location and 25 hiding it. Just an idea. Never did it myself. Just thought it would be neat if I were to be so inspired.
