Can films be stacked to dry?

• A. Yes
• B. No, the films must not touch when drying
• C. Only if air is circulating
• D. Only for certain types of film

Answer: (B)

Drying films needs air to flow around each piece so the moisture can evaporate evenly. When films touch while drying, the gelatin emulsion can stick to the adjacent film, causing blocks or transfer of emulsion and making separation damage the image. Stacking also traps moisture between surfaces, leading to uneven drying and potential artifacts. Keeping films apart on a drying rack or hanging them with space between ensures consistent drying and avoids damage. The idea that films can be stacked is not consistent with how emulsion-based films dry, even if air is circulating.
