Sharpness Scoring

RawCull can score a catalog by estimated sharpness and sort the grid with the sharpest images first.

Sharpness scores are automatic estimates. Always inspect important or borderline images yourself before rejecting them.

Run Scoring

1. Open a catalog and wait for thumbnails to finish.
2. Open the grid.
3. Select Score Sharpness.
4. Wait for scoring to finish.
5. Use the Sharpness sort toggle to show sharpest images first.

After scores exist, the button changes to Re-score. Use it after changing scoring parameters or focus mask settings.

Score Badges

Scores are relative to the current catalog. A high score means the image is sharp compared with other images in the same session.

Scores from different catalogs should not be compared directly.

Scoring Parameters

The grid shows a Scoring Parameters control for choosing the scoring style.

Fast scoring is best for normal culling. High Precision and RAW Demosaic are slower and are better for final checks.

Focus Mask

Sharpness scoring also calibrates the focus-mask threshold for the current catalog. Use the focus mask in zoom view to inspect where RawCull sees sharp detail.

The Focus settings control threshold, pre-blur, amplification, erosion, and dilation. Lower threshold shows more highlighted detail; higher threshold keeps only stronger edges.

Tips

• Score after removing obvious exposure mistakes.
• Use sharpness sorting to find the best frame in a burst.
• Use focus mask before rejecting a low-scored image.
• Re-score after changing scoring type, quality, source, or focus mask settings.
