At what temperature is it suggested to store photographic material?

Photographic materials, such as films and x-ray films, are sensitive to temperature and light, and their quality can deteriorate if not stored properly. The recommended storage temperature for these materials is typically between 60-70°F. This range helps to minimize the risk of fogging, color shift, and other forms of degradation that can occur at higher temperatures.

Storing photographic materials at this optimal temperature also contributes to maintaining the emulsion's stability and sensitivity. Temperatures that go beyond this range can accelerate chemical reactions within the photographic materials, leading to a decline in image quality.

In contrast, the other options suggest either too high a temperature, which can be detrimental, or temperatures that may not be ideal for preserving the longevity and effectiveness of the photographic materials. Thus, maintaining a storage temperature of 60-70°F strikes the right balance needed to ensure that the materials remain in their best condition for use.
