Film can be in the heat without being ruined, but long periods of exposure will greatly affect it. As you can see below, the heat muted the colors, brought the contrast down, and had a significant impact on overall quality. Also asked, how can temperature affect the processing of a film?
Higher developing temperatures and increased developing times resulted in an increase in film speed and film contrast. A definite pattern of change could be demonstrated in film speed and film contrast during sensitometry.
Similarly, does temperature matter when developing black and white? The real tricky part, however, is managing temperature. Black-and-white film requires a rather comfortable 68 degrees or optimal development. It can go up into the '70s and down as cold as 65 degrees if you make some minor adjustments to developing time.
Considering this, can cold temperature damage film?
In the cold, film becomes extra fragile. If you've ever tried to load film right after pulling it out of the freezer, you know how brittle it can get. So, be sure to load your film extra carefully and advance it through your camera slowly when shooting in the cold.
What causes film reticulation?
Reticulation as I mentioned above, is a distortion of the emulsion layer – primarily caused by extreme change in temperature during processing, which causes silver grains in the emulsion to “clump together†into patterns. These resulting patterns are called reticulations.

What is the effect of developing temperature in quality image?
Development TemperatureAn increase in temperature speeds up the development process and increases film sensitivity because less exposure is required to produce a specific film density.
What is the ideal developing temperature?
Ideally, your film developer and other chemicals should all be used at 68°F. In reality, temperatures can vary widely unless you have an expensive fluid control system installed in your darkroom. Fortunately, we have found an easy Fahrenheit chart that works great. Which factor determines dental film exposure time?
Both intraoral and panoramic x-rays machines have the following exposure factor controls: milliamperage (mA), kilovoltage (kVp) and time. How does filtration affect contrast?
Our experiments showed that appropriate filtrations could reduce certain low- and high-energy components of X-ray spectra which have limited contributions to image contrast. At the same time, such filtration could improve the contrast-detail detectability, particularly at relatively low kVp and high filtration. What temperature is too cold for film?
It says right on film packages: 55 degrees F, stored at or below that is. Film should be in the fridge for short term storage and in the freezer for longer term storage. Film loves cold weather, but I wouldn't let it freeze in the camera in the car. storing film in the fridge is normal practice. What happens to film in cold?
Images from improperly stored or old films will get a “fog†like effect with less contrast. Low temperatures slow down film degradation. High temperatures speed up film degradation. Freezing stops the film degradation. Should I put my film in the fridge?
As a general rule, film will perform its best when shot fresh. Color film should be refrigerated if it's being stored for up to 6 months, while B&W film can be stored at room temperature. When you plan to keep film longer than six months, leave it sealed inside the plastic canister in the freezer for best results. Will expired film damage my camera?
What kind of effects will you get from expired film? The primary effects of age on photographic film are decreased sensitivity and contrast, increased grain, and color shifts. Color shifts may be subtle or extreme, depending on both the age and the storage conditions. What temperature should I store film at?
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. Should I refrigerate 35mm film?
Yes, storing them in the fridge is a good idea. The cool temperature slows the degradation of the film. Additional benefit is gained from the stable temperature. To prevent condensation, being an issue, simply take the film out of the fridge the evening before you intend to use it. How do you store film negatives?
Put clean negatives in polyethylene sleeves. This kind of plastic is safe and won't cause any damage to film. Make sure to store negatives flat. We recommend you put them into sleeves and store them in a binder or lay them flat in a plastic box made of polypropylene.
