Frozen film will be brittle and may crack during camera loading or transport. Furthermore, condensation may build up as the film equilibrates to the temperature of its environment. Condensation may cause ferrotyping and moisture static (tacky film) which may cause a static discharge. ¶ Let the film warm up to ambient temperature before the can is unsealed. This will prevent any cold-induced problems. Typical warm up times for 16 mm film is one hour (1) for a 14°C rise (25°F), 35 mm film is three hours (3) for 14°C rise (25°F). If the film is used in subzero temperatures there are devices available to warm the camera and magazines so that the film can run smoothly and silently. Contact your local Kodak Sales and Engineering Representative for more specific information.
