As an experiment, we took a photo using two rolls of 35mm Fujifilm Pro400H film, a standard roll, and one exposed to heat in a car for two days. As suspected, heat does have an effect, and below is an example of a test we did.
Film can be in the heat without being ruined, but long periods of exposure will greatly affect it. As you can see below, the heat muted the colors, brought the contrast down, and had a significant impact on overall quality. As someone pointed out on our Facebook, it looks like an Instagram filter was applied. See below for other interesting reactions and comments from our Facebook post.
Photos were taken with a Canon EOS 3 / 85mm.

But that’s what people want it to look like these days for some reason, add a light leak and some dust and you’ve got yourself an Instagram winner 🙁 – Burien Y
Baked film can be beautiful. Baked film can be ugly. Lol. In this case I prefer the degraded values. – Brandon W
I am shooting the last package of 16 year old Kodak Pro-400 that has been stored cool, seems fine after the C-41…be careful with low temp storage, don’t open the pack until it reaches room temp or you get condensation… -Jon A H
People pay good money for that effect. And I live in Phoenix, what am I to do? -John B
