Effects of Humidity

Motion picture raw stock is packaged in taped cans. Until opened, the cans are water and vapor tight and do not require humidity-controlled storage. However, avoid storage at relative humidities of 60 % or above. Such high humidities can damage labels and cartons (from moisture and mold) and can rust the cans.

Note: Keep raw stock in its original taped can until you are ready to use the film.

High humidity can promote mold growth and ferrotyping. Low humidity can create static marks when printing or cause buckling due to uneven moisture loss. Exposed film, particularly color film, deteriorates more rapidly than unexposed film. Kodak recommends exposing and processing all camera films soon after purchase and no longer than six months after purchase. Immediately after exposure, return the film to its can and retape the can to help prevent any increase in moisture content. Process the film as soon as possible after exposure.
