Another difficulty for OP may be controlling the kind and the amount of damage caused to the film. I would this he/she would want the damage to fall somewhere between none at all and totally trashed. It may be easier to do this post processing, like get a film processed and torture the strip via various method before printing.
I used to work in a minilab - I know of wherefore I speak. I probably printed several thousand rolls of the stuff in the course of my four years at the store. The only time we saw stuff that looked BAD was when it was old enough to qualify for a drivers license. This is not to say we didn't get stuff that showed signs of aging (decreased contrast, increased grain, color shifts), but it was almost never unprintable and rarely hideous.
I want to force expire some film quickly. Don't worry it's not expensive film (Kodak Gold). Anybody know what's best I thought of sticking it through the dryer, or in the toaster oven. Anybody know what's best?
Ill try it in the glove box for a week or two. Thanks for all the responses! I'm looking to make it look like its been expired for a few years. StoneNYC, when I find the best way to expire it and then get it developed (i get it done at Costco) I'll get back to you
OK, you put it on the dashboard of your car and drive into Death Valley. Make sure all the windows are closed and then leave the car and hot foot it out of the valley (this may pose a problem and you may need a bottle/several bottles of water). Return after a couple of months, retrieve your car and film and process it. Hay presto!
