Braga, você tem razão; tenho costume aqui de guardar as especificações técnicas de vários filmes. Dei uma pesquisada e notei uma coisa. Poucos dizem algo sobre resfriar o filme. Alguns sugerem temperaturas abaixo de 15 ou 21° C e somente um ou outro documento que tenho menciona congelamento. A Kodak mesmo parece ter um padrão nessa especificação:
Store unexposed film at 21° C (70° F) or lower in the original sealed package. Always store film (exposed or unexposed) in a cool, dry place. Process film as soon as
possible after exposure.
Veja aqui pro 400cn:
Store unexposed film at 21°C (70°F) or lower in the original package. Always store film (exposed or unexposed) in a cool, dry place. Though this film has excellent latent image keeping characteristics (after exposure, but before processing), for best results, process film as soon as possible after exposure.
ou o 400 TX:
High temperatures or high humidity may produce unwanted quality changes. Store unexposed film at 24°C (75°F) or lower in the original sealed package. Always store film (exposed or unexposed) in a cool, dry place. For best results, process film as soon as possible after exposure.
