Cold but not damp, by jusdeep on Mar 6, 2013 15:18:25 GMT 1, Not sure cold would be a problem, but humidity or dampness caused by temperature change. I would be more concerned that the prints are in the tubes and the long-term effect of this. Storage flat with acid free paper in an safe and neutral environment would always be preferable. Photographic prints are generally stored in colder conditions.

The problem with any paper is movement. As paper has a memory and contracts and expands as wood with heat and moisture. Somewhere like a loft would be hot in the summer and very cold in the winter so vast temperature changes might cause problems. Far better to store in a spare room where the temperature and humidity remain constant and away from light and radiators.

As a general rule temperature should be set at between 65-70°F, humidity at 30% - 40%
