Checking Adobe Firefly output
Verify Firefly renders and generative-fill edits before they ship
Firefly’s pitch is commercial safety — trained on licensed content, designed for enterprise. That covers where the pixels came from, not whether they are right. A generative-fill edit can still leave a seam, a warped hand or a physically impossible reflection sitting inside an otherwise real photograph, which makes the defect even harder to spot in review.
What typically goes wrong in Firefly output
- Blend seams and texture mismatch where generative fill meets the original photo
- Objects extended by fill that lose their geometry — railings, window frames, patterns
- Rendered text and logotypes inside generated regions
- Anatomy errors when people are extended or retouched generatively
- Lighting direction in filled regions disagreeing with the source photo
How Chekr checks it
Chekr scans the flattened export — photo, fill and all — so defects introduced by any generative step are judged in the context of the finished composite. The artifact, texture-coherence and lighting checks are exactly the ones that catch fill seams and mismatched shadows.
The provenance check reads Content Credentials where present (Adobe tools attach them), and the reverse-image check verifies the composite has not landed too close to existing work — licensing of training data does not guarantee distance from any specific image.
Frequently asked
Firefly is trained on licensed content — is IP risk gone?
Reduced at the training-data level, not eliminated at the output level: an image can still resemble existing work, and resemblance is what a viewer or rights holder reacts to. The reverse-image check measures that directly.
Does Chekr check Photoshop generative-fill edits?
Yes — upload the flattened export. The scan does not care which pixels are original and which are generated; it judges whether the finished image holds up.
Are Content Credentials preserved?
The forensics check reads C2PA metadata when the file still carries it and reports what it finds — including when an export or optimization step has stripped it.
