How should photographic materials be stored to prevent pressure damage?

• A. Flat; never on edge.
• B. On the edge; never flat.
• C. On the edge; never flat.
• D. Standing upright.

Answer: (C)

Photographic materials are damaged by pressure from the weight of other items pressing down on their surfaces. When kept flat, the entire surface bears weight, which can lead to emulsion cracking, flattening, or surface damage over time. Storing on the edge means the items rest along their narrow edge, so weight is supported along that edge rather than across the face. This significantly reduces the pressure on the emulsion and helps preserve image quality and shape. Standing upright without proper supports can lead to tipping or leaning and isn’t as reliable as edge storage with appropriate shelving. So, store on the edge and avoid flat storage.
