Skin Tone Enhancement

Skin tone adjustment (Lpars)

Skin tones are easy to overcorrect. VIESUS detects faces and prevents them from becoming oversaturated.

Example

Before (Skin)

Enhanced by VIESUS

After (Skin)

Enhanced by VIESUS with adjusted Lpars.skin

Parameters

Parameter	Range	Default	Description
skinToneAdjFac	0.0 – 1.0	0.2	Saturation reduction (adaptive) in face regions (prevents "glowing" faces)

Skin color zone (Lpars.skin)

Fine-tune the skin tones globally. These parameters live in the Lpars.skin sub-section and use the same set as the other local color corrections.

Lpars.skin targets a color range, not detected skin regions. Warm, earthy tones like sand, desert rock, and sunset skies can fall into this zone too, not just skin.

Parameter	Range	Default	Description
strength	0.0 – 1.0	1.0	Overall strength of adjustments for the skin zone
brightness	-1.0 – 1.0	0.0	Brightness adjustment for the skin zone
contrast	-1.0 – 1.0	0.0	Contrast adjustment for the skin zone
saturation	-1.0 – 1.0	0.0	Saturation adjustment for the skin zone
huerotation	-10 – 10	0.0	Hue rotation for the skin zone

Recommended: Leave skinToneAdjFac at 0.2 — it keeps faces from glowing while preserving natural color. Adjust the Lpars.skin zone only when you need to target skin tones specifically; VIESUS already balances them automatically.
