Since the recent news of the discontinuation of some films beloved by our clients (we’re looking at you Fuji400H) we’ve been getting more questions about storing your film in the fridge or storing film in the freezer. Should I put my film in the fridge? Can I freeze my film? How long will my film last in the fridge? Are just some of the questions we received in the last weeks so we thought we would dedicate a post to sharing everything you’ll need to know about refrigerating and freezing your film. Let’s get started!
We recommend striving to shoot fresh film when and where you can. By “fresh film” we mean film that has been recently acquired and has not expired. The reason is that fresh film is at its peak for capturing and delivering the truest colour and the best possible results. Kodak Alaris Product Manager Tim Ryugo did a very interesting post about it recently:

When you’re not able to shoot fresh film, there are some things that should be done to retain a film’s potential so that you’re not sacrificing too much quality, and that is to properly store your film in cold storage. Unprocessed film is a perishable product that can be damaged by high temperature and high humidity (but that being said, we recommend you check out our Understanding Film Flaws post to see how even damaged film can still make its own magic).
Consequently, putting your film into cold storage will increase the lifespan of your film and provide you with the best possible results even if your rolls are a few years old.
*It may be worth noting: Color films are more seriously affected than black-and-white film because adverse conditions usually affect the emulsion layers to various degrees. So when your box of colour film arrives from Carmencita Film Lab, put it into cold storage if not using it immediately.
If you plan on using your film in less than 6 months, you should put your film in the fridge, right next to your milk and leftover gazpacho. In general, manufacturers recommend storing your emulsion at 8°C /46°F or lower.
The lower temperature will slow down film degradation and the dry atmosphere in the fridge will protect film from humidity. That being said, refrigeration will not be able to reduce the effect of gamma radiation. Naturally occurring gamma radiation will increase the minimum density and can also increase grain. Consequently, the higher the speed of your film that you have stored in your fridge the more it will be affected than any lower speed films you have stashed.
How long does film last in the fridge? Well, as we said, the cold will slow down film’s natural degradation, if we take 20ºC as the standard temperature and we store it around 5 ~ 8ºC / 40 ~ 46ºF we are basically stretching the film’s expiration date by almost x2,5 times.
As a rule of thumb, if the film you just purchased expires 2 years from now, if you put it in the fridge it will maintain its fresh condition for at least 5 years.
That being said, films (exposed or unexposed) that have been properly refrigerated will retain the speed and contrast of the exposure conditions, but the overall minimum density and grain will continue to increase as time passes due to the natural ageing process.
If you plan on not using those films for the next 6 months, we recommend putting your film in a tightly sealed container or a ziplock bag and then putting it in the freezer (-18°C / 0°F or lower). The tightly sealed container should protect your film in the event you lose power and things turn into a lake in your freezer.
Putting your film in the freezer puts your film into a sort of hibernation. You can keep your film in the freezer for as long as you need; we’ve known clients who have left theirs in the freezer for 15 years and it’s still good to use!
For both instances of cold storage for your film you want to avoid humidity. Humidity will speed up film degradation, it’s basically film’s kryptonite. It can create dark spots on your 120 film, make your 35mm stick together in the canister and make your film look expired even if it was fresh.
To protect against humidity, we recommend including a silica gel desiccant bag into the film storage container that will go in the freezer. We also recommend that you store your film unopened and in its original canister or its plastic wrap.
TAKING YOUR FILM OUT OF COLD STORAGE
At some point you will probably want to bring your precious rolls back to life, right? When taking your film out of the refrigerator, we recommend allowing it around 2 hours or more to adjust to room temperature prior to shooting it.
When taking your film out of the freezer, we are going to need to proceed with a little more caution:
- Ideally: Take your film out of the freezer and let it sit in your fridge for the next 24 hours, that will guarantee the slowest and safest defreeze. After 24 hours in the fridge, take it out of the fridge and leave it out to adjust to room temperature for a couple of hours, and then you are good to go!
- Less ideally: If you kinda need your film ASAP, we recommend taking it out about 6 hours or more to adjust to room temperature. This will defrost your film quickly, but the process will not be as gentle for the emulsion. Keep in mind: never heat up your film to unfreeze it faster, your film is a marvellous piece of technology not a bunch of frozen vegetables 😛
In both instances, we recommend that you leave your film in its canister until it has had the chance to adjust to room temperature. Doing so will prevent it from ending up covered in condensation. You can confirm your film is at room temperature by taking the film out of its canister and confirming that it’s not cold to the touch.
SHOOT IT, DEVELOP IT
Lastly, we recommend shooting the whole roll, exposing it correctly like this fantastic post explains to you How Exposure Affects Film and sending it off to your favourite lab, for example Carmencita Film Lab, for development as soon as you can.
Left a film roll or a loaded camera in your car on a hot summer day? Chances are you will have some baked film after that. There are countless situations like this where life and accidents happen. But don’t let that stop you from shooting or developing those film rolls.
Essentially: don’t keep film in your camera for longer than necessary; your film will go bad if not developed. Leaving partially-exposed film in your camera for a few weeks or months until the next time you shoot leaves room for your film to degrade due to atmospheric changes. Not only that, you’ll have to wait longer to see your results! And who has time for that? 😉
