How to fix a photo that’s half grey, smeared or cut off

The top of the photo looks fine, then it turns flat grey. Or there’s a smeared band, or everything below a line has the wrong colours. All three have the same cause — and they’re often very fixable.

What’s going on

A JPEG photo is stored as a long stream of small picture blocks, one after another. Your phone or browser reads them from the top down. When it hits damaged data, it can’t make sense of anything after it:

• Grey from a line downwards — the reader gave up at the damage. The rest of the picture is usually still in the file.
• A smeared or noisy band — the reader kept going but lost its place for a while.
• A sudden colour shift — the reader recovered but its colours are off from that point on.
• Grey with no damage before it — the file is simply cut off. The missing part was never saved.

How Recovery Monk fixes it

It does automatically what photo-repair experts do by hand:

1. Reads the picture blocks itself to find exactly where the damage starts.
2. Searches past the damage for the point where good picture data resumes.
3. Puts filler blocks in place of what was lost, so the rest of the picture lands where it belongs.
4. Shifts the colours of the rest so they match the part above.

It tries several ways of doing this and keeps the one that looks most natural. On real photos with random damage, it brought back most of what looked lost. A thin strip where the damage was may stay flat or smeared — that bit of data is genuinely gone.

And if the photo is just cut off?

Most phone photos carry a small preview copy of themselves inside the file. Recovery Monk uses it to fill in the missing part, so you get a complete picture — sharp where the real data survived, softer where it came from the preview.
