Even after you have painstakingly digitized your photo collection using a scanner and PhotoSplit Studio, the original physical prints remain incredibly valuable. They are the primary source material, the tangible artifacts of your family's history. Unfortunately, most people unknowingly store their photos in environments that actively destroy them. Here is how to ensure your physical prints survive for generations.
The Enemies of Photographs
To protect photos, you first must understand what destroys them. The four primary enemies of photographic prints are:
- Light: Specifically Ultraviolet (UV) light. Continuous exposure to sunlight or fluorescent lighting causes the dyes in color photos to fade and yellow rapidly.
- Heat: High temperatures accelerate the chemical degradation of both the photographic emulsion and the paper base. Heat also makes the emulsion sticky, causing stacked photos to fuse together.
- Humidity: High moisture environments (above 60% relative humidity) encourage mold and mildew growth. Conversely, extremely low humidity causes prints to become brittle and curl.
- Chemical Pollutants: Acidic paper, cheap glues, and PVC plastics outgas harmful chemicals that stain and degrade photos over time.
The Rule of Three: Cool, Dry, and Dark
The cardinal rule for storing any physical archive is to keep it cool, dry, and dark. Let's look at what that means practically in a typical home.
Where NOT to Store Your Photos
Never store your photo boxes or albums in the attic or the basement. Attics experience wild temperature fluctuations—baking hot in the summer and freezing in the winter—which causes expansion and contraction that cracks photo emulsion. Basements are prone to dampness, flooding, and mold.
The Ideal Location
Store your photos in a climate-controlled living area. A closet shelf in a main hallway, a bedroom, or an interior room is ideal. You want an environment where the temperature stays relatively consistent (around 68°F/20°C) and the humidity remains moderate (between 30% and 50%).
Choosing Archival Storage Materials
The container you place your photos in is just as important as the room you store them in. Beware of cheap, mass-market photo boxes and albums.
The Danger of "Magnetic" Albums
If your photos are stored in "magnetic" or "self-adhesive" albums from the 1970s through the 1990s, they are in grave danger. These albums used highly acidic cardboard pages coated with a sticky glue, covered by a sheet of PVC plastic. Over time, the acidic glue turns yellow and bonds permanently with the photos, while the PVC outgasses and destroys the color dyes. If possible, gently remove your photos from these albums immediately using a thin spatula or dental floss.
What to Look For: The PAT Test
When buying storage boxes, sleeves, or albums, look for products that have passed the Photographic Activity Test (PAT). This is an international standard testing method developed by the Image Permanence Institute that guarantees the material will not chemically react with your photos.
- Boxes: Use acid-free, lignin-free archival boxes. Avoid regular cardboard or wood, which emit harmful gasses.
- Plastics: If using plastic sleeves, ensure they are made of uncoated Polyester (Mylar), Polypropylene, or Polyethylene. Never use PVC (Polyvinyl Chloride).
- Paper: Use acid-free tissue paper to interleave between delicate prints or fragile negatives.
Handling and Organization
Human hands contain oils and acids that can leave permanent fingerprints on photo emulsion, which may take years to become visible. When handling your archival collection, wash and thoroughly dry your hands first. For highly valuable or historical prints, wear clean white cotton or nitrile gloves.
When organizing prints in an archival box, group them by size and pack them snugly, but not too tightly. If they are packed too loosely, they will curl over time. If they are packed too tightly, the pressure can cause the emulsions to stick together, especially if the temperature rises.
Conclusion
Preserving physical photos requires an initial investment in archival materials and a thoughtful choice of location, but the payoff is immense. By keeping your prints cool, dry, dark, and away from acidic materials, you guarantee that the tangible links to your family's past will remain vibrant and intact long after they have been safely backed up on your hard drive.
