Thanks for the response. I was beginning to think no one out there would have an answer.
I don't want to loose the image. I just want to increase the contrast and grain. Or see any of the other effects heating the film might have. I plan on shooting the 16mm film, cooking it, then processing it. What happens if I keep reheating it a few times, keeping it under 85 degrees F? If the emulsion flakes off will the image still be visible? I'm thinking not.
Cheers,
