Smart Blur
Smart Blur blurs while preserving edges — noise reduction and softening that doesn't smear outlines the way a plain Gaussian blur does.
Parameters
| Parameter | Type | Range | Default | What it does |
|---|---|---|---|---|
| Radius | number | 1 to 20 | 5 | The size of the area considered for smoothing. |
| Sigma | number | 0.1 to 20 | 10 | How different pixels need to be before they're treated as an edge and preserved. |
