Hi Ishikawa, Thanks for the ilustration. The camera is ready, I made it yesterday, and is almost exactly as you pictured, I made it with cardboard. The main diference is that film placed at the position "a" is also bended, U shape. The idea is producing a kind of a "triptico" (I don't know the name in English). I am not sure if it will work, but I'll give it a try and post the results to the upload galery. The next one will probably be a pvc cilinder with the film placed against the wall, forming a cilinder. Thanks for the help with the matter.
Joao
