When it comes to preserving your old films, photographs, and magnetic tapes, time is not the only threat. Environmental conditions — particularly temperature, relative humidity, and light exposure — can silently accelerate decay.
We work with many of our clients to help them employ archival-grade storage solutions for their collections. The below guide is designed for people who don't have access to expensive solutions but still want to give their media collection the greatest chance of survival.
1. Maintain Stable Temperature and Humidity
Temperature and humidity are the most important factors in slowing deterioration.
Relative Humidity (RH):
- Ideal for most home-stored collections: 30–50% RH
- Avoid dropping below 30% RH (materials can become brittle)
- Avoid exceeding 55% RH (mould growth risk rises sharply)
Temperature:
- For general storage: Below 20°C
- For long-term storage of acetate or polyester film: 10–15°C
- Magnetic tapes benefit from cooler conditions: ≤18°C
Why it matters: Chemical reactions — such as vinegar syndrome in acetate film and hydrolysis in magnetic tape binders — are accelerated by heat and moisture.
Pro Tips: Stability matters as much as the numbers — avoid rapid fluctuations, which cause expansion/contraction and physical stress (To control the climate conditions of your home you can purchase affordable solutions such as dehumidifiers or Hygrometers).
2. Protect from Light and UV Radiation
You've probably heard the saying, 'A picture fades over time', well this is one of the key contributors to this effect. Light damage is irreversible and cumulative so your safest method of keeping your items in good condition is to follow these two rules.
- Store items in dark, enclosed cabinets or boxes.
- Avoid direct sunlight entirely — UV rays cause fading and embrittlement.
3. Use Simple, Safe Storage
Even if you don’t have access to expensive materials, you can still protect your memories!
Photos: Store them in basic, clean boxes or envelopes (just make sure they're not regular cardboard, which can damage photos over time).
Film Reels and Tapes: Keep them upright in a plastic or cardboard box to avoid bending or pressure.
General Tip: Just avoid using cheap plastic sleeves or folders that can release harmful chemicals over time.
You don’t need high-end storage, but keeping things in a dry, cool place and away from sunlight will make a big difference.
4. Avoid Damp or Uncontrolled Environments
Basements, lofts, and garages are among the worst storage locations because they are prone to humidity spikes and condensation.
- Choose an interior room with stable conditions.
- Use silica gel or molecular sieves to control moisture (replace/recharge regularly).
- Keep items off the floor and away from exterior walls to reduce risk from leaks.
5. Handle Media with Care
Even clean hands contain oils and salts that can cause long-term staining or corrosion.
- Wear nitrile or lint-free cotton gloves.
- Hold photos and films by their edges.
- Keep food and drinks away from storage areas.
6. Check Once a Year
Make it a habit to give your collection a quick health check.
- Look for mould spots, strange smells (vinegar odour in film, musty smell for mould), or sticky tape surfaces.
- If you spot trouble early, you have a much better chance of saving the content - often by digitising it before it’s too late.
Why This Matters
Every reel, print, or cassette in your collection is a one-of-a-kind piece of history. Following these scientifically backed guidelines can add decades — even centuries — to their life.
While these tips can help you care for your physical collection, digitising your memories means they’re safe no matter what. With our Memory Box digitisation services, we help preserve your photos, tapes, and films as they exist today—securely stored in the Cloud, ready to be shared and enjoyed by your entire family, anytime.
Preservation isn’t about locking your memories away; it’s about ensuring they remain accessible, viewable, and safe for future generations.
