What AI photo restoration can’t do

AI restoration can’t recover information the original photo never captured. When a model sharpens a blurry face or enlarges a tiny scan, it predicts what probably belongs there, based on millions of other images. The result can look convincing and still be wrong. Use it to make a better viewing copy, and keep the original as the record.

Recovering versus predicting

Some edits only rearrange information that is already in the picture. Removing a yellow cast or restoring faded contrast works that way: the tones were there, just shifted or compressed. Local Photo Restore’s Remove Yellow Tint and Restore Contrast controls are this kind of adjustment. They don’t add content.

Super-resolution is different. When Enhance turns a 512-pixel scan into a 2048-pixel image, three out of every four new pixels in each direction have to come from somewhere. The model fills them with texture that is statistically likely: crisp edges, plausible hair strands, fabric weave. That’s why enhanced photos look sharper. It’s also why some of that sharpness is invented.

Where invented detail shows up

  • Small faces. A face that was 30 pixels wide in the scan has no reliable eyelashes or teeth to recover. Face-restoration models, used by apps like Remini and MyHeritage, go further and generate a whole face. It can resemble the person, or a stranger.
  • Text and numbers. Blurry signs, dates, and handwriting can become crisp-looking letters that say something else.
  • Fine patterns. Lace, brick, foliage, and film grain can turn into repeating textures.
  • Colors in black-and-white photos. Colorization picks likely colors; the real dress may have been blue rather than red.
  • Missing areas. Tools that fill tears or holes paint in content that was never photographed.

Local Photo Restore avoids the most aggressive of these: it doesn’t generate faces, colorize, or fill damage. Enhance can still sharpen detail beyond what was recorded, especially on very small inputs.

What AI restoration also can’t fix

  • Glare from photographing a glossy print. Retake the capture instead. See how to photograph old prints.
  • Heavy motion blur or out-of-focus originals. Enhancement makes edges crisper, not correct.
  • Physical damage (in Local Photo Restore): scratches, tears, stains, and creases remain. Options for damaged prints.
  • A screenshot of a tiny thumbnail. Start from the largest, cleanest copy you can find.

How to keep an honest family archive

  1. Keep the original scan or capture untouched, with its original file name. Local Photo Restore always saves a new copy, which helps.
  2. Label enhanced copies, for example by adding “enhanced” to the album or caption.
  3. Compare at 100%. Use the before/after divider and pinch in on eyes, mouths, glasses, and jewelry. If a detail changes character, prefer the less-processed version.
  4. Be careful with evidence. Don’t use an AI-enhanced image to settle who someone was, read a date, or prove what a place looked like.
  5. For heirloom or legal needs, use a professional archival scan and a restorer who documents their changes.

So is it worth using?

Yes, for what it’s good at. A faded, yellowed snapshot that nobody looks at can become a photo people want to print and share. The goal is a clearer, more viewable copy of a memory, alongside the untouched original, not a replacement for it.
