I want to experiment with creative uses of purposely damaging color film, mainly for distortion/color effects.
A friend of mine was given a box of dozens of somewhat-recently expired rolls of 35mm Fujicolor Superia X-tra 400 film from a friend of his working in the photolab at a local Costco.
After shooting several rolls, we're discovering the batch has a pretty ugly magenta color cast. It's not enough to ruin the film, but enough to require subtly filtering the scene green to make skin not look so gross..
This is our stock and reason for wanting methods of purposely damaging the film..
But we can't damage the film so much that we can't still take it to our local el-cheapo photolab.
I know most of this is simply trail-and-error, but I'd like to find out some baseline
tolerances and ideas of others who've tried similar things, either for creative purposes or from quality control testing..
But my (Google) searches have come up short.
Or web sources for such info?
..at the moment our ideas only go as far as heating, and possibly radiating the film. Heating elements considered: the natural approach, leaving rolls in a sun-soaked car (~100-120ºF?) for X period of time.. vs. "cooking" rolls in an oven (short of physically melting the film) at XºF for X period of time. Maybe heating followed by rapid cooling X number of times.. etc.
Maybe even nuking the film in a microwave. Either by removing the film from the canister and microwaving through a plastic/paper light-tight box, or even zaping the film through the metal canisters.. I'm willing to risk a little mayhem if it could result in bizarro random spark patterns throughout the roll..
But again, if anyone has tried or knows of someone who has tried similar techniques, we're looking for potential starting and breaking points.
The key is, it has to enhance/distort the (latent) images up to the point of utter abstraction, but without entirely destroying the images or the film..
