Inputs (5)
| Name | Type | Default | Description |
|---|---|---|---|
| algorithm | COMBO | cam16ucs | off: disable output gamut compression. cam16ucs (default): CAM16-UCS chroma reduction with the smoothest constant-hue behavior. oklch: perceptual chroma reduction in OkLab, preserves hue + lightness. aces_rgc: per-channel ACES RGC v1.3, matches Resolve/Nuke/OCIO. oklrab/jzazbz: alternative perceptual spaces. |
| knee_threshold | FLOAT | 0.000–10000 | Reinhard knee (threshold, limit, power) on normalized chroma C/C_max. Default (0.0, 1.0, 6.0) rolls off smoothly from the center with the asymptote on the output cube edge. |
| knee_limit | FLOAT | 1.000–10000 | Reinhard knee (threshold, limit, power) on normalized chroma C/C_max. Default (0.0, 1.0, 6.0) rolls off smoothly from the center with the asymptote on the output cube edge. |
| knee_power | FLOAT | 6.000–10000 | Reinhard knee (threshold, limit, power) on normalized chroma C/C_max. Default (0.0, 1.0, 6.0) rolls off smoothly from the center with the asymptote on the output cube edge. |
