Storing and processing film on long journeys (Latin America)
I'm taking off soon for a roadtrip throughout Latin America where I'll be shooting 35mm e-6, c-41 and b&w film. I'm expecting to be on the road for the better part of the next year so I've got ~80 rolls with me.
I have installed a small 12v compressor fridge in my truck to keep the film from getting cooked under the tropical sun. I'm hoping that is sufficient and the fridge doesn't fail.
I'm wondering what I will do with the exposed film. I could just keep putting it in the fridge and drive it back home eventually. This is my default option.
One alternative is shipping the film back to the states periodically. I don't have much confidence that it would arrive safely.
Will I be able to find labs that can do decent processing? Where would I find them? I can save up and batch process film when I hit major cities.
Recommendations for Latin America?
I could but I don't really want to carry a dark bag & tank & chemicals if I can avoid it. I figure that since I won't be equipped to do all my film, why bother processing any of it?
I wouldn't mind processing the film locally from time to time but I'm worried that I won't be able to find and vet good labs. In the US, it's getting harder and harder to find places. I usually ship my E-6 film out to be processed since the last local processor in town is now closed. The local C-41 lab does a terrible job (mishandling negatives, mixing up orders, etc).
I have no idea what to expect in Mexico, Central and South America. How do film hobbyists in those locations process their film? Are there any labs I should add to my list of destinations?
