To preserve old family photographs, store them flat in acid-free, lignin-free enclosures, keep them in a cool, dry, dark place away from light and humidity swings, handle them only with clean hands or cotton gloves, and digitize them so a backup exists. When you display the originals, frame them with UV-protective glazing and archival (acid-free) mats so the photo never touches the glass. These few habits do most of the work of keeping a hundred-year-old portrait readable for the next generation.

Why do old photographs fade and deteriorate?
Old prints are made of paper, gelatin, and light-sensitive chemistry, and every one of those layers reacts to its environment. The biggest enemies are predictable:
- Light — especially ultraviolet (UV) from sunlight and fluorescent bulbs — fades dyes and yellows paper.
- Heat and humidity — warmth speeds chemical breakdown, and damp air invites mould and causes prints to curl or stick together.
- Acids — found in ordinary cardboard, construction paper, “magnetic” peel-back albums, newsprint, and many older frame backings. Acid migrates into the photo and causes brown spotting and brittleness.
- Air pollutants and physical handling — fingerprints leave oils that etch the emulsion over time.
How should you store old photos safely?
Storage is where you win or lose the long game. A photo spends far more time in a box than on a wall, so the box matters most.
- Use archival enclosures. Choose sleeves, folders, and boxes labelled acid-free, lignin-free, and ideally that have passed the Photographic Activity Test (PAT). Polyester (Mylar/Melinex), polypropylene, and polyethylene are safe plastics; avoid PVC, which off-gasses.
- Store flat, not crammed. Lay prints horizontally in a box so they support each other without bending. Don’t overstuff.
- Control the climate. Aim for cool and stable — roughly 18°C or below with relative humidity around 30–50%. Avoid attics, basements, and exterior walls where temperature and moisture swing.
- Separate the originals from contact with each other. Interleave with acid-free tissue if prints are stacked, so emulsions can’t stick.
- Keep them in the dark. A closed archival box in a closet inside the living space is ideal.
What about damaged, curled, or stuck-together photos?
Resist the urge to “fix” valuable originals yourself. Don’t peel apart stuck prints, apply tape, or trim edges. For severe damage — water, mould, or photos fused to glass — consult a professional photo conservator. For everyday cleanup, a soft, dry brush to remove loose surface dust is usually as far as you should go.
Should you digitize before you frame?
Yes. Digitizing is the single best insurance policy because it separates the image from the fragile object. Scan at a high resolution (600 dpi or more for standard snapshots, higher for small or detailed prints), save uncompressed TIFF masters plus JPEG copies, and back them up in more than one place. Once a high-quality scan exists, you can reprint, restore, enlarge, and share copies freely while the original rests safely in storage. Many people choose to frame a fresh, color-corrected reprint and keep the century-old original tucked away — a smart way to enjoy the photo daily without exposing the irreplaceable one to light.
How do you frame an old photo without damaging it?
Framing an original is essentially building a small, protective museum case. The goal is no acid, no direct contact with glass, and no UV.
- UV-protective glazing. Use conservation or museum-grade glass or acrylic that blocks most UV light — the main cause of fading on display.
- Acid-free matting and a spacer. An archival mat (or a hidden spacer) keeps an air gap between the photo and the glazing. Prints pressed against glass can stick permanently or trap condensation.
- Reversible mounting. Hinge the photo with archival photo corners or acid-free tissue hinges. Never use regular tape, rubber cement, or dry-mount adhesive on something irreplaceable — the mounting should be undoable.
- Acid-free backing board behind the photo, plus a sealed dust cover.
- Smart placement. Even with UV glass, avoid hanging directly across from a sunny window or above a heat source.
If a beloved print is fading or you simply don’t want to risk the original on the wall, the cleaner route is to scan it and order an archival reprint. A local custom framer such as Supreme Pictures in Mississauga can handle the conservation framing, and quality photo printing in Mississauga lets families across Mississauga and Brampton put a faithful copy on display while the heirloom stays protected.
Frequently asked questions
Is it safe to laminate an old photograph?
No. Lamination uses heat and adhesive that bond permanently to the surface, it is not reversible, and it can accelerate deterioration. Use an archival sleeve or a properly framed enclosure instead.
Can I hang an original family photo in direct sunlight if it’s behind glass?
It’s risky. Ordinary glass blocks little UV, so the image will still fade. Use conservation or museum glazing and, ideally, display a reprint while the original stays in dark storage.
How often should I check stored photos?
Inspect them once or twice a year for signs of moisture, mould, sticking, or pests. Catching a humidity problem early is far easier than reversing damage after it spreads.
