I just bought a mini fridge from Amazon and a couple days later I noticed some Is condensation. Is humidity bad for film even of its in their original canisters and unopened boxes? I also was thinking about buying silica packs to absorb moisture.
shouldn't affect it as long as it is in its original packaging, I'd think.I just bought a mini fridge from Amazon and a couple days later I noticed some Is condensation.

That's the best practice and then take them out of the fridge a day or two before using film.I wouldn't trust the standard packaging if stored over a longer period of time. Doubt that these are all 100% impermeable with respect to diffusion of gases, humidity etc. I seal my films additionally before putting them into a fridge.
+1I keep the unopened film in a ziplock with a silica gel packet in the freezer. Once opened I don't refreeze film.

That seems chancy to me. You've never had condensation inside the zip lock?Once opened, the film goes into the refrigerator in a Zip-Lok bag.

Actually, the air might be at lower relative humidity at higher temperatures. But it can hold more water vapor than at lower temperatures. That's why it always feels so dry in your throat during the winter and you need a humidifier. That's why humidity is always called relative humidity because it depends on what the temperature is. One square foot of air at let's say 30 degree F holds 1 pint of water vapor and reads 50% RH. But at 85 degrees, you can quadruple the water vapor and it will read 50% as well (These amounts are not accurate. I am just showing that there is a huge difference in RH and vapor depending on the temperature of the air).Camera stores keep their film refrigerated at a higher temperature than what is used for food (think florist's refrigerator). I think that might also contribute to lower humidity inside the refrigerator. Follow the manufacturers' recommendations. Unless, of course, you are freezing he film.
I just store black and white film in an insulated cooler bag.
That is not to say the California is a dry state.

This is why you have to be careful when you go from outside in winter into a hot house with your camera. The air around the cold camera cannot hold the moisture in your hotter house. So it condenses on the camera's metal or lens. In effect, it's reaching its dew point like dew on the grass on a cold morning.
No the dry state is Utah, isn't it?

My first question is how long a film is to be stored? A fridge is better than room temperature, and a freezer is better still. I'm using film that has been frozen for over thirty years with no ill-effects.
Plan for the long term. Buy a freezer, and buy up film stock you like. You might be the only person here with access to Tri-X in thirty years! (Well, I've a hell of a lot of it but I won't be here in thirty years.)
I have the same experience how ever change the 30 years to approximately 20 years for me.
All film is packaged against humidity. Once it's opened, moisture could damage the film. What causes condensation is humid getting chilled by the freezer. If it's just black and white film, I would not put it back in the fridge once you open it if you plan to use it up in less than a year. Just store your film in a cool, dark and dry place.I just bought a mini fridge from Amazon and a couple days later I noticed some Is condensation.
