Preservation of physical materials is an ongoing activity; photos must be inspected periodically over time to monitor any degradation and ensure that they continue to remain in good condition.
☐ Store photos away from light, at a reasonable temperature
Storage conditions are typically the most important factor in ensuring that photographs remain intact and don’t degrade. There are many types of photograph formats, for which different storage conditions may be optimal. The main considerations for photo storage include:
- Temperature & humidity – Cooler temperatures (under 75 degrees Fahrenheit) and between 15-65% humidity provide the best environment. Avoid fluctuations in temperature. Consider cold storage for negatives and older color photos.
- Light exposure – All photographs are sensitive to the sun as well as light bulbs, so limiting light exposure to both is essential.
- Storage materials – Most papers contain acid that can degrade photos over time, and some plastics can be abrasive. Use acid-free paper and archival plastic storage enclosures to keep photos safe. (See the “Assessing Your Collection” section for where to find storage materials.)
DO NOT store photos in an attic, basement, or outdoor storage shed with unregulated temperature and humidity:
Poor storage conditions like an outdoor storage shed can accelerate the degradation of photographs.
☐ Handle photos carefully in a clean environment
☐ Do not use paperclips, rubber bands, adhesives, or write on photos
Handle your photos with care. Human error, such as getting greasy fingerprints on photos or accidentally scratching them, can cause problems that are avoidable as long as you:
- Wear gloves when handling
- Pick photos up carefully using both hands
- Don’t have food or drink near photos
- Don’t write on photos (front or back)
- Don’t put adhesive on or near photos
- Don’t use paper clips, staples, rubber bands, or any other fasteners that could cause damage
