I have been mostly lazy till now and have used the few C-41 films that are still available. Looks like I am gonna have to fashion a splitter for 120/220 film, and reload my own cassettes now. I will be a good excuse to start this project. 16mm film will work (Plus-X and Tri-X are available), but it would have to be sent out, and first I have to find a motion picture processing place that will take such short strips of film. Also, gotta be OK with sprocket holes on the frames to do that.
