Preserving Old Photographs: A Complete Guide to Scanning, Storage & Digital Backup

Short answer: get the original prints out of the shoebox before another decade of acid migration ruins them. Scan at 600 DPI for normal prints and 1200 DPI for anything you might want to enlarge or restore. Save the masters as TIFF, share JPEGs. Keep three copies in three places — original prints in an archival box, a local hard drive, and a cloud backup. Then, and only then, start restoring.

Why scanning matters more than restoring

We talk a lot about AI restoration on this site, but restoration is downstream of preservation. If the original print is sitting in a non-archival album, exposed to light, or stuck to its neighbour by a 1980s adhesive, the photo is degrading every week. Restoration recovers what's still there; preservation stops what's still there from disappearing.

A photo print is a physical object subject to physical entropy. Acid in cheap cardboard albums migrates into the print and yellows it. UV light bleaches dyes. Humidity grows mould. Stuck pages tear emulsions when separated. By the time you decide to "do something about the old photos," another five years have ticked by.

Step 1 — Pull the originals out of harm's way

Before you scan a single photo, do triage. Sort photos into three piles:

• Immediate rescue — anything mouldy, stuck to glass, water-damaged, or in a magnetic ("self-adhesive") album from the 1970s–80s. These are decomposing right now.
• Standard preservation — everything else. Most snapshots, school photos, holiday packs.
• Negatives and slides — these are the masters. They contain more information than any print made from them, so they're highest priority for high-resolution scanning.

For the "immediate rescue" pile, see our visual guide to damage types for what to do with each specific problem — water damage, mould, sticking, fading all have different first-aid steps.

Step 2 — Choose the right scanner

Flatbed scanner (best for most prints)

A modern flatbed like the Epson Perfection V600 (~$280 AUD/USD) is the right answer for 95% of home archives. It scans prints, negatives, and slides at proper archival resolution and the colour calibration is reliable enough that your TIFF masters won't need post-correction.

Avoid: cheap all-in-one printer scanners (resolution is overstated, colour is unreliable) and "wand" scanners (you can't keep them perfectly flat).

Dedicated film scanner (best for negatives/slides)

If you have a lot of 35 mm negatives or slides, a dedicated film scanner like the Plustek OpticFilm 8200i (~$500) or Pacific Image PrimeFilm XAs gives noticeably sharper results than a flatbed's film attachment. Worth it for serious archives; overkill for casual.

Phone apps (last resort)

Google PhotoScan and Photomyne use the multi-angle trick to remove reflections from glossy prints. The output is JPEG, ~6–8 MP, with some sharpening artefacts. Fine for "I need to text this to my sister right now"; not fine as your only archival copy.

Professional bulk service

Services like ScanCafe and Memories Renewed charge ~$0.30–$0.80 per print to scan in bulk. Cost-effective if you have 1,000+ photos. Watch out for resolution (some quote 300 DPI as standard — push them to 600+) and turnaround (4–8 weeks is normal).

Step 3 — Get the resolution right

Resolution determines how much detail is captured. Once you've scanned at 300 DPI and thrown the original back in the box, you can never go back. So scan high the first time.

• Snapshots up to 6"×4": 600 DPI
• Larger prints (5"×7" and up): 1200 DPI
• Anything you might want to enlarge or hang on a wall: 1200 DPI minimum
• 35 mm negatives and slides: 2400 DPI minimum, 3200–4000 DPI ideal
• Medium and large format negatives: 1200–1600 DPI (the original is already huge)

Higher DPI = bigger files. A 6"×4" print at 600 DPI is ~20 MB as TIFF; at 1200 DPI it's ~80 MB. A 1 TB external drive holds about 12,000 high-res TIFF scans, which is more than the entire archive of most families.

Step 4 — Save the right file format

Save scan masters as TIFF (uncompressed or LZW-compressed). TIFF is lossless — the file on disk is bit-for-bit what the scanner captured. JPEG re-compresses every time you save, and after a dozen saves the artefacts are visible.

For sharing and day-to-day use, export JPEG copies from the TIFF masters. This way:

• The TIFF is your archival master. You never edit it directly — you work on a copy.
• JPEGs are derivatives you can recreate any time from the master.
• If 20 years from now there's a new compression format (HEIC, AVIF, whatever), you re-export from the TIFFs.

Do not: save as JPEG at "high quality" and call it done. Even maximum-quality JPEG drops detail your AI restoration tools could have used.

Step 5 — Name and organise the files

File naming is the difference between an archive and a digital shoebox. The convention that actually survives long-term:

YYYY-MM-DD_short-description_001.tif

So 1972-08_brisbane-holiday_003.tif sorts chronologically forever and tells you what's in the photo without opening it. If you only know the year, use 1972_. If you don't know the year at all, use undated_ and put it in an "undated" folder — but try to identify the year first by asking living relatives. That information dies with people.

Step 6 — Back up to three places (the 3-2-1 rule)

This is the rule professional archivists use:

• 3 copies of every file
• 2 different types of media (e.g. local hard drive + cloud)
• 1 copy offsite (cloud counts; so does "at my sister's house")

Practical implementation for a family archive:

1. Originals (physical prints): archival boxes from Archival Methods or similar, in a climate-stable interior cupboard. Not the attic, not the garage.
2. Local copy (hard drive): a 2–4 TB external drive plugged into a home computer. Replace every 5 years — drives degrade.
3. Cloud copy: iCloud, Google One, OneDrive, Backblaze, or pCloud. ~$10/month for 2 TB. The cloud copy survives the house fire your local drive doesn't.

Test the backups once a year. A backup you've never restored from is not a backup; it's a hope.

Step 7 — Now you can restore

Once you have clean, high-resolution TIFF masters safely backed up in three places, the original prints are no longer a single point of failure. Now is when you bring out the AI restoration tools — on copies of the digital masters, never on the only file you have.

Practical workflow: copy the TIFF master to a working folder, run it through the appropriate restoration tool (Standard for faded prints, Comprehensive for serious damage, Colorize for B&W), and save the result as a new file alongside the master. Now you have the original scan AND the restored version — both, forever.
