What is the recommended storage temperature for photographic materials?

• A. 85-95 F
• B. Less than 75 F, with 60-70 F preferred
• C. 32-40 F
• D. 100-110 F

Answer: (B)

Photographic materials age as heat speeds up chemical reactions that fade dyes, shift colors, and weaken the emulsion and binder. Keeping them in a cooler, stable environment slows these processes and extends their life. A storage temperature below 75 F, with around 60-70 F being ideal, offers effective preservation without the risks that come with freezing or very warm conditions. Warmer ranges, like 85-95 F, accelerate deterioration; freezing temperatures (32-40 F) can cause condensation and mechanical damage, and very hot ranges (100-110 F) are even more destructive. So the best practice is a cool, stable room temperature around 60-70 F.
