STORAGE AND HANDLING
Store unexposed film at 21° C (70° F) or lower in the
original sealed package. For extended periods, store film at
13° C(55° F) to preserve consistency.
To avoid moisture condensation on film that has been
refrigerated, allow the film to warm up to room
temperature before opening the package. Typical warm-up
times are given in the table below.
Load and unload roll-film cameras in subdued light.
Total darkness is required when you load and unload sheet
film holders.
Process film as soon as possible after exposure. Protect
negatives from strong light, and store them in a cool, dry
place. For long-term storage, keep negatives at a
temperature between 2° C (35° F) and 13° C (55° F) and at
a relative humidity between 30 and 35 percent.
DARKROOM RECOMMENDATIONS
Do not use a safelight. Handle unprocessed film in total
darkness.
