Algorithm
Preset level
Amount 150%
Strength of the contrast boost at edges. 50–150% suits most photos.
Radius 2.0px
How wide the effect spreads. 0.5–1px = fine detail, 3–10px = broad punch.
Threshold 3
Minimum edge contrast before sharpening kicks in. Higher = skip smooth areas (skin, sky).
Intensity 2.0
1.0 = no change · 2.0 = noticeable · 5.0 = aggressive.
Edge enhance uses a fixed high-boost kernel. No tuning knobs — one-click sharpening for quick results.
