I'm just curious about temperature affects on film. I usually store my film in the fridge for the most part but I concerned with repeated cooling and warming of the film. Also, I attend alot of airshows and the gear gets pretty warm in my car, in my bag and for that matter in my hands. Now I haven't seen any issues with a day spent in a hot car but what about longer? I've been leaving my camera stuff in my trunk and was wondering if a continually warm/hot environment would affect film quality?
