I was thinking about something yesterday and thought I would get some opinions on here. I shoot mostly 135 and 120 film and I always have my camera bag in the car with me (it's like a habit at this point, I'm more likely to forget my wallet at home than my camera bag). I will usually leave my bag in the car for most of the dya while I am at work and in class. Is it safe to leave film in such hot temperatures? I haven't noticed much of a difference in IQ but considering it is best to store film in a freezer, does leaving my film/cameras in the car have any adverse effects on the film?
