Use the score as a triage signal
- Choose the same exported image you plan to deliver or print.
- Compare similar photos captured with the same workflow rather than treating the score as universal.
- Inspect low scores at 100% before discarding an image.
Image Sharpness and Clipping Checker
Estimate local edge detail, shadow clipping, highlight clipping, and average luminance without sending the photo to a server.
Focus problems, motion blur, aggressive noise reduction, and small sources can all reduce edge detail. This checker provides a repeatable technical signal and pairs it with exposure clipping so photographers can triage batches more quickly.
How OpenFileTools processes it
Local processing, explicit choices.
The browser downsamples to a bounded analysis canvas, calculates luminance, applies a lightweight Laplacian edge-detail estimate, and reports clipping/brightness metrics from the same sample.
Questions, answered.
Is this an AI blur detector?
No. It is a transparent edge-detail heuristic, which keeps processing fast and private.
Can I compare two similar shots?
Yes. Scores are most useful when comparing images from a similar scene and processing workflow.
