Restore an Old Photo with AI

How it works, and what it does not do

Three operations, in order. The scan is colorized by DDColor, then sharpened, and the sharpened version is blended back over the colorized one at partial strength so the sharpening is applied gently rather than at full force.

That is the entire graph, and the omission in it is the most important thing on this page: there is no inpainting step. Nothing here fills a hole, rebuilds a torn corner, removes a crease, or paints out a stain.

"Restore" is a broad word and it is worth narrowing before you upload a photograph you care about. What this does is color and clarity. What it does not do is repair.

Why damage repair is a genuinely different problem

Colorizing asks a model to add a layer of information over structure that is fully present. Every pixel is there; only the hue is missing.

Repairing damage asks it to invent structure that is absent. Where a photograph is torn, the file contains no record of what was behind the tear, so anything that appears there was decided by a model rather than recorded by a camera. On a family photograph that distinction matters more than usual, because the thing being invented is often part of a person.

Those two jobs need different machinery, and running one does not partly accomplish the other. A creased photograph put through this workflow comes back as a colorized, slightly crisper photograph with the same crease.

What it does handle well

General fading. An old print that has lost contrast overall — no single defect, just a uniform tiredness — is the case this was built for.

Softness from the scan itself, or from the original print being a contact copy or a reprint. The gentle sharpen addresses exactly that.

Grayscale prints that would read better in color for a modern audience, which is usually the reason someone wants an old family portrait processed at all.

What it will not fix

Tears, creases, missing corners, punch holes, and anything stuck to the surface.

Foxing, the brown speckling on old paper, which will be colorized as though it were part of the image.

Silvering, the metallic sheen on the dark areas of old prints, which the model reads as tone rather than as damage.

Severe blur or camera movement, which is not softness and is not addressed by sharpening.

In each of these the honest sequence is to repair first, by hand or with a tool built for it, and to run this afterwards.

Before you scan

Scan the print rather than photographing it, at the highest optical resolution available, with any automatic sharpening and dust removal switched off. Those features guess, and you want the guess to happen once, visibly, in a step you chose.

Clean the glass and the print surface. Dust becomes permanent detail.

Keep the original scan untouched and work from copies. The point of restoring a family photograph is to end up with more than you started with, and overwriting the only digital record of the print is the one outcome that cannot be undone.
