film recommendations for extreme heat (50 degrees plus)

looking for a recommendation.

i need a low iso film that can handle temperature swings from the freezing point up to 50 degrees plus in a 24 hour period.

as well, any recommendations for storing on the person? i will have to carry it for an extended period of time. it will be a bring only what you can carry situation with water taking up 90% of the room.

thanx in advance!

I don't think that the temperature swing is such a big deal - almost any film will handle that rate of change

The cold and hot do funny things to your brains - its very hard to think straight when you are very cold or very hot - so use something you are already familiar with - it uses less brain power so less chance of a mistake

Storage is more of an issue

Water and film are not a happy combination.

Leave the film in either the canister (35mm) or foil wrap (120) until the last possible minute to keep it dry, clean and dirt free for as long as you can.

I have found that locking/sealing food containers are the most practical - my choice are Lock n Lock containers - I can open them with gloved hands - YMMV

What ever container you choose it ought to be water tight - water bottles often leak and condensation might be an issue

Good luck and have fun
