6. gage Visual checks are always safer This applies in particular to high speed films because the sensitivity of a film to X rays is proportional to its sensitivity to visible light Storage Remember never to store films under moist or humid conditions Neither should films be exposed to heat Unexposed films The cooler an unexposed film is stored the longer it will last Furthermore we recommend keeping the film in the original pack which is moisture proof i e water tight so that the photographic qualities remain stable Films that have been stored in a refrigerator should be kept at room temperatu re for about two hours before use as the atmospheric humidity might otherwise produce condensation on the cold film A car glove compartment is not suitable for storing films If the sun is hot they can easily develop temperatures of up to 80 C 175 F Fumes such as formaldehyde can also be harmful They are released by furniture cosmetics adhesives and varnish The camera itself only provides inadequate protection Instead put your camera in a polyethylene bag if necessary Exposed films Once exposed a film should be developed as soon as possible The latent image i e the pre development exposure may otherwise deteriorate as a result of long term storage or unfavourable weather conditions and this disturbs the colour balance Developed films The same safety precautions apply to develo ped films i e they must be ke
