How to restore old photos without harming the original
Leave the print as it is and repair a copy of its scan. Dust, fading and small tears can be fixed digitally. Flaking, mould, water damage or prints stuck to glass need a conservator.
Restoring an old photo is usually two separate jobs. One is digital repair of a copy. The other is care of the physical print, which is a conservator's work once it is damaged.
The American Institute for Conservation notes that much photographic deterioration cannot be reversed. Treat the print as the evidence and the edited file as a reconstruction.
Make a digital scrapbook
Add your photos and keepsakes in tbf scrapbook, then arrange them on the pages.
| Damage | On the digital copy | On the original print |
|---|---|---|
| Dust and specks | Healing brush, zoomed in | The Library of Congress recommends an air bulb, not canned air; even a soft brush can scratch |
| Fading | Levels or curves, then colour balance | Keep it in the dark and display a copy instead |
| Colour cast | Colour balance against a neutral white or grey | Store it as cool as you can; colour prints are more sensitive to warmth |
| Small tear | Clone texture across the line | Support the print without adhesive; ask about a suitable enclosure if fragments move |
| Crease or crack | Heal and clone along the fold | Support as found; do not press brittle or cracked layers flat |
| Missing piece | Rebuild the background or crop, and note it as rebuilt | Keep any loose fragment in the same envelope |
| Mould spots | Heal on the copy | Keep it apart from other photos and contact a conservator |
| Stuck to glass or another print | Scan or photograph it as it is | Contact a conservator; do not prise it free |
| Flaking or lifting surface | Photograph it from above without touching | Contact a conservator |
Keep three files
Keep the untouched scan, a working file with your edits, and a finished copy for a book or print. Names such as 042-scan, 042-work and 042-final keep the order obvious.
Edit at the scan's full size. Repair done on a small file cannot put back detail that was never captured, and enlarging it later shows every brush stroke.
Copy the back of the photo too, including names, dates and studio marks. Keep a change log beside the working file: region edited, tool used and anything reconstructed rather than recovered.
What home editing can fix
Most photo editors offer the same core tools under different names: a healing or clone brush, levels or curves, colour balance and crop. Between them they handle everyday damage.
- Dust and specks: a small healing brush, zoomed in, one spot at a time.
- Fading: set the darkest and lightest points with levels, then adjust the middle tones.
- Colour cast: correct a red or yellow shift with colour balance against something that should be white or grey.
- Small tears and creases: clone matching texture across the line from both sides in short strokes.
- A missing corner: rebuild plain background from nearby, or crop if nothing important is lost.
Where repair turns into invention
Rebuilding an eye, a mouth or lettering that is no longer visible is guesswork. If you do it, say so in the file name or caption and keep the scan beside it.
Colourising a black-and-white photo makes an illustration of the scene, not a record of it. Put the black-and-white version next to it in any book.
Automatic restoration can change faces and expressions. Compare each result with the scan at the same size before you keep it.
When the print itself needs a conservator
The American Institute for Conservation lists water or fire damage, flaking or lifting layers, rapid change, mould or pests, broken glass, and negatives smelling of vinegar.
AIC's Find a Professional directory can locate specialists in photographic materials. Ask for handling and housing advice for the item's condition; do not clean, glue or flatten damaged surfaces.
Prints stuck together or stuck to frame glass are a common case. Do not pull them apart; the image layer can stay on the other surface.
Steps
Lock the master
Save the scan, make the file read-only, and duplicate it for editing.
Fix the whole image first
Straighten and crop, then set levels and colour balance before touching single spots.
Work from small damage to large
Remove dust first, then cracks and tears, then missing areas. Save a version after each stage so you can step back.
Compare and note
View the finished copy beside the scan at the same size. Note anything rebuilt in the file name or caption.
Questions
Can a photo be restored without the original print?
A copy can be repaired from any scan or photo of it. Detail lost in a small or blurred copy cannot be recovered, only redrawn, so say which parts were redrawn.
How much does professional photo restoration cost?
It varies with the damage and with whether the work is digital retouching or conservation of the print. Ask for a written estimate that says which one you are paying for.
Should I repair the print itself or only the copy?
Only the copy, at home. The Library of Congress says condition problems that better housing cannot solve may need treatment from a photograph conservator.
