Measure a photo's average brightness, contrast, and exposure balance from the real pixels — the lighting checks a face-verification flow runs first. In-browser.
A quick utility: An analyzer that measures a photo's lighting from its actual pixels: average brightness, contrast, and how balanced the exposure is.
▶ Open the tool — runs entirely in your browser; nothing is uploaded.
Poor lighting — too dark, washed out, or low contrast — is a leading reason a face-verification or liveness step rejects an image. This reads the pixels in your browser and reports the numbers plus a simple verdict, so you can fix lighting before submitting.
It measures the image only; it does not detect faces, and the file is never uploaded.
- Drop or choose the photo.
- Read average brightness, contrast, and the share of very dark / very bright pixels.
- Retake in more even light if anything is flagged.
No. It is drawn to a canvas locally to read pixel values. Nothing is sent.
Roughly mid-range on a 0–255 scale, with enough contrast (spread) and not too many blown-out or crushed pixels. Exact requirements vary by service, so treat a pass as 'likely fine'.
No. It measures lighting and exposure, which is what most verification flows gate on first. Face detection needs a model this tool does not run.
