[QUOTE="User 67, post: 8055, member: 67"]There are few people who have experience with unrolling old film. If you do it successfully, I would guess that you will end up with more experience than a friend who does photography. Lay out some glassine on a dresser, put a neg on the glassine. Bring a humidifier into the room, (the kind that you use w/vicks for a kid) and let it go. It is difficult to test for the humidity levels unless you have expensive equipment or meters like you find at a museum or lab or fur vault, so set the humidifier on low, face the nozel away from the film and let it do it's magic for a day or two in a sealed off room, as suggested. Celluloid is in a constant state of decay, it gives off a characteristic chemical smell. It is also highly flamable and reacts to different chemicals (ammonia, peroxide, alcohol etc.) so chemicals of any kind should be used with caution. It is hard to say how stable the emulsion is, soaking in water may release the emulsion from the film, and depending on the plastic used, it may soften the plastic too much, getting into tiny cracks and softening those more, to turn it into a pile of mushy sided fragments. If the humidity treatment works, you could combine that with a heat treatment before pressing the flim, placing a room heater in to raze the room temperature to 90°. Idealy in a Museum situation, they would raise the humidity slowly over the course of a few weeks to a month.[/QUOTE]
