Old photos are irreplaceable, and the wrong storage materials can damage them faster than leaving them in a shoebox. Here is how to do it right.
Use acid-free materials
Acid is the enemy of photographs. Over time, acidic paper and adhesives cause yellowing, brittleness, and fading. Look for archival-quality, acid-free albums and sleeves with a pH of 7.0 or higher.
Avoid PVC plastic
Polyvinyl chloride (PVC) releases gases that degrade photo emulsion. Choose polyester (Mylar), polypropylene, or polyethylene sleeves instead. They are chemically inert and safe for long-term storage.
Store in a cool, dry place
Heat and humidity accelerate chemical breakdown. Aim for storage below 70 degrees Fahrenheit and under 50 percent relative humidity. Avoid attics, basements, and garages where temperature fluctuates.
Label with archival tape
Use photo-safe, removable adhesive label tape to identify dates and names on album pages. Never use regular masking tape or cellophane tape near photographs.
With the right materials, your photos will look as good in 50 years as they do today.
