How Do I Detect Manipulated Return Photos?

Spot edited or AI-generated damage photos in returns in six checks — forensic indicators, not snap verdicts, with the metadata to back them up.

An edited damage photo costs you a refund that was never owed. This guide shows how to vet a suspect claim photo in a few minutes — no forensic background, and without accusing anyone prematurely. The full mechanism behind it lives on our manipulated damage photo detection page.

The six on-screen visual checks

Step-by-step

Inspect a suspect damage photo

Six checks in order. Stop the first time two of them flag.

  1. Find the light source
    Where does light fall from? In a single-source scene every shadow must fall the same way with consistent softness. Two shadow directions suggest a composite.
  2. Compare shadow hardness to the ambient light
    A scratch on a dimly lit table has a soft shadow edge. A razor-sharp shadow around the 'damage' reveals different lighting at render time.
  3. Check reflections on glossy surfaces
    Plastic, glass and varnish reflect their surroundings. If the reflection does not match the rest of the photo, that region was painted in.
  4. Zoom to 400% on the damage edges
    Edited regions leak artefacts at the boundary: halos, repeated micro-textures (content-aware fill) or transitions that are too hard.
  5. Read the JPEG noise pattern
    Sensor noise is statistically uniform across one exposure. Patches with noticeably cleaner or busier noise were reprocessed.
  6. Align the perspective
    An inserted defect rarely respects the surface's vanishing lines. Draw two vanishing lines — the damage should follow them.

You do not need a trained eye. Two flags out of six is enough to look closer.

The technical layer: metadata and ELA

What the eye misses often sits in the metadata: tags from an editing suite, or a completely missing camera record, are strong first-pass indicators. An error-level analysis (ELA) additionally surfaces regions compressed differently from their surroundings. How Claimscan cascades these stages without calling expensive models on every image is covered in our REST API overview.

Frequently asked questions

Can you prove for certain that a photo was edited?
No, and no serious tool claims to. You combine several independent indicators into a likelihood. The return decision always stays with a human.
Is one suspicious signal enough?
No. A missing metadata block or a hard shadow alone is not evidence of manipulation. Only two or more independent signals together are reliable.
Does Claimscan also detect AI-generated damage photos?
Yes. Alongside pixel and metadata forensics, Claimscan runs a specialised AI-image detector and a provenance (C2PA) check, so the result rests on several independent signals rather than one model's opinion.
