Stephan_Chandler Posted May 17, 2008 Share #1 Posted May 17, 2008 Advertisement (gone after registration) I’ll keep unexposed film for quite a while, sometimes years… in the freezer. My regimen would be… 1.) Take the film from the freezer, 2.) Wait four or five hours, 3.) Load and shoot the film, 4.) If not to be processed right away, return the film to the freezer. BUT… what about all the time that my loaded cameras sit in my car’s trunk? That’s the most convenient place for me to keep them. But I’ve discovered it gets hot in that trunk when in bright sunlight all day. And sometimes those cameras remain there for weeks or months. So how may I retard film deterioration (if any) during that time? Reflectors? Insulators? Link to post Share on other sites More sharing options...

andybarton Posted May 17, 2008 Share #3 Posted May 17, 2008 Given that the film should only be in your hot car boot for a few hours, I wouldn't worry about it. However, you say that the cameras live in the boot for weeks or months? That doesn't sound good. In that case, you should get the film processed as quickly as possible. The only alternative would be to move to Alaska, or Norway Link to post Share on other sites More sharing options...
R.Morrison Posted May 17, 2008 Share #4 Posted May 17, 2008 In a hot boot isn't a good environment for your camera either. Consider the rubber impregnated silk of the shutter screens. Mind you it is away from the eyes of theives. Yours, R. Morrison, M4-P, etc. Link to post Share on other sites More sharing options...
Guest darkstar2004 Posted May 17, 2008 Share #5 Posted May 17, 2008 Heat damage to your cameras and lenses is the thing to be paranoid about!! Heat is at least as destructive to cameras and lenses as is water, if not moreso. I worked in a camera shop for awhile and saw alot of lenses that had been heat damaged. Heat causes the lubricant that is in the aperture mechanism to change states. It looks as if the aperture blades have been greased with Vaseline. Not good. Not good at all. The result is that the parts that need the lubricant no longer are lubricated properly, resulting in metal-to-metal friction damage. Heat does the same thing to camera bodies. The newly formed "grease" also slows down the working of the aperture blades (an issure more for SLR lenses) and impedes propelr function; this can throw off proper exposure (shutter opens, aperture is not fully stopped down due to slower operation). Heat can cause the adhesives that bond lens elements together to fog and/or delaminate and it can damage the coatings on lens surfaces. Never leave a camera bag in a hot car - passenger compartment or trunk. Never. The same applies to the rear cargo area of SUVs. If the car is too hot for a human to sit in comfortably, it's too hot to leave your cameras and lenses in. Given the bloodcurdling prices of qulaity photographic gear - Leica equipment in particular - I'd rather err on the side of safety. Regarding film, if you keep it frozen before and after exposure - the time that it is at ambient temperature while you are using it or preparing to use it is pretty much a non-issue as far as emulsion aging goes. Freeze it, store it, use it and then get it processed promptly or refreeze it till you get it processes and it will be fine. But never leave your cameras and lenses in a hot car!!!!!

dennersten Posted May 18, 2008 Share #6 Posted May 18, 2008 I traveled by car through Sahara some years ago, so i called Kodak about this. They only guaranteed colour stability up to 35 degrees celcius as i remember it(or was it 40?). It can easily be up to 60-70 degrees in your trunk. So you should'nt keep your cameras and film there. They also said that black and white are no problems, extremly heat resistant. I solved it by installing a secondary battery in my Land Rover and a fridge. Always brought the cameras with me. And i have a lot of beatiful pictures from Sahara to enjoy these days. Link to post Share on other sites More sharing options...
Mark Antony Posted May 18, 2008 Share #7 Posted May 18, 2008 Advertisement (gone after registration) Buy a $5 picnic cooler bag should keep the film at 10°c especially if you buy one that has pockets for those re-usable plastic freezer blocks. Remember that temperature shock;- going from freezing to 30°c in seconds can be damaging also so the cooler picnic bag can be used as step between frozen and ready to use. No need to freeze B&W film unless you plan to keep it way past sell by dates, develop promptly for best results. Mark Link to post Share on other sites More sharing options...
Stephan_Chandler Posted May 18, 2008 Author Share #8 Posted May 18, 2008 Thanks, guys, for all your helpful information. Seems I'll be changing the errors of my ways... odd how potential dangers can be at first overlooked! Link to post Share on other sites More sharing options...

Mark I have used hard plastic picnic/beer/food coolers to keep my camera bag in during obnoxiously hot summers to stop heat damage when I had to leave them in the car. You can throw in a frozen cooler pack to help keep the temperature inside within reason. Just something to think about... Link to post Share on other sites More sharing options...
