General:

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. 
• Always store film (exposed or unexposed) in a cool, dry place.
• To avoid moisture condensation on film that has been refrigerated, allow the film to warm up to room temperature before opening the package. 
• 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.

Do not use a safelight. Handle unprocessed film in total darkness.
