Inputs (9)

Name	Type	Default	Description
image	IMAGE		—
mode	COMBO	manual_offset	2 options: target_ire, manual_offset
detection_mode	COMBO	mask_only	3 options: combined, hsv_auto, mask_only
target_ire	FLOAT	700–100	Target mean skin luminance in IRE (Y-space). 70 = broadcast standard skin tone. The shift is applied perceptually (L* space) so it looks uniform across shadow and highlight areas of skin.
manual_offset	FLOAT	0.00-1–1	Direct additive Y offset applied to skin pixels. +0.1 lifts by 0.1 Y units (about 10 IRE). -0.3 darkens by 0.3 Y units. Full range: -1.0 to +1.0.
strength	FLOAT	0.500–1	—
skin_threshold	FLOAT	0.100.01–0.9	Skin confidence threshold - behavior depends on detection_mode. COMBINED (recommended): pixels inside the SAM mask whose skin confidence is below this fraction of the PEAK confidence inside the mask are excluded. Skin-tone-agnostic: 0.10 always means 'exclude the bottom 10% of skin-likeness for this person' - eyes, teeth, eyebrows - regardless of complexion. Start at 0.10. Raise to 0.20-0.25 to also exclude lips. Lower to 0.05 if shadow areas of skin are being incorrectly excluded. HSV_AUTO (no mask): threshold applied to raw confidence score (0-1). Start at 0.25-0.35. Raise to exclude warm backgrounds or clothing.
feather	FLOAT	80–64	Softens the outer boundary of the skin selection. COMBINED: feathers the SAM mask edge (hairline, shoulder, jaw). The skin interior stays clean at weight 1.0 - feather only affects the edge. HSV_AUTO / MASK_ONLY: feathers the confidence or mask boundary directly.
