4 things to check in photo restoration services

What to take away

The four checks, with the answer each one needs:

Check 1: the processing standard behind a new print

Processing decides whether a new print outlives the original. The Canadian Conservation Institute's note on processing photographic films and papers for permanence states that correct processing contributes significantly to longevity.

Correctly processed silver gelatin films and fiber-base prints are essentially stable to dry heat and visible light. They stay vulnerable to aggressive chemicals.

The failure the note singles out is a processing one. Compounds used in the fixing step can cause black and white photographs to discolor. Residual fixing salts may seriously jeopardize permanence.

Ask four questions before a negative leaves the house. What chemistry does the new print use. Does the wash meet an archival standard. Is the print toned. Is the paper fiber-base or resin-coated.

Fiber-base paper usually outlasts resin-coated paper, and toned prints resist fading better than untoned ones. How to judge a lab's work covers the same questions asked face to face.

Check 2: sorting wet collodion from gelatin dry plates without a lab

Wet collodion plates run from roughly the mid 1850s to the 1890s. They look milky brown and were usually varnished. Aged varnish adds greatly to stability and lends a brownish-yellow tone.

Gelatin dry plates began replacing them in the 1880s. They show crisp black, gray or clear tones. A blue metallic sheen often sits in the densest areas. That is silvering out, image silver that has migrated to the surface.

The Canadian Conservation Institute's note on the care of black-and-white glass plate negatives divides them into wet collodion and gelatin dry plates. Those differences decide handling, preservation and basic cleaning.

The chemistry then decides what may touch the plate. The collodion layer is soluble in alcohol and acetone. The gelatin layer is insoluble in absolute ethanol. A method safe for one plate will destroy the other, and household cleaning is the archive mistake that does the most damage at home.

Do not rub the blue sheen or use silver polish. It is part of the image silver.

Hand any service one question list: which solvent will you use, will you test a corner first, and what happens if the image layer lifts. Get the answers before the plate leaves your house.

Check 3: scan specifications and the single archive copy

The scan is the master file. Ask for a TIFF at 600 ppi for prints, or 4000 ppi for film and glass plates. Request 16-bit color if the file will be retouched.

Ask whether the service sharpens, crops or colorizes by default. Ask for the unedited file as well, because a restored file that cannot be reversed is a new object, not a record. Ask for a drive plus a cloud copy that does not expire.

Then split the order. The archive copy is one well-made print or file, stored properly. The family copies are ordinary prints in quantity, and they can fade in thirty years because the archive copy carries the information.

Before you commission a repair, our notes on the three jobs behind one name explain why a scan, a repair and a reprint price out separately and seldom belong in one order.

Check 4: the quote, five named services and what to buy first

Order matters more than brand. Scan every damaged item first, then buy enclosures, then order prints against one archive copy.

Typical market ranges as of 2026, not quotes: scanning runs $0.25 to $1 per photo for a basic JPEG, and more for a TIFF. Per-image restoration runs $20 to $100.

Five services publish enough detail to compare, though not the same columns.

Ask each one the same four questions: what is the file spec, who does the retouching, what is the turnaround, and what happens to the original. The answers will not match, and the differences are what you are paying for. Keep the replies in writing. gov/consumer-complaints) sets out the filing route.

For sleeves, boxes and dividers, our guide to what to buy first for a photo archive covers paper or plastic, buffered or neutral, so the cheap step does not compete with the scan bill.
