Channel Curves
Edits Red, Green, Blue, and Luma tone curves using control points and Bezier handles.
| Parameter | Control | Range | Notes |
|---|---|---|---|
| Edit channel | Selector | Red, Green, Blue, Luma | Other active curves remain visible but dimmed. |
| Solo | Rocker | Hides the other channels’ curves. | |
| Active | Rocker | ||
| Curve well | interactive curve graph | X and Y each 0 to 1 | Click the curve to add a point; select a point to adjust its Bezier handles. Delete, Backspace, or Remove point removes the selected point. The first and last points cannot be deleted. Double-click, Alt+click (Windows/Linux), or Option+click (macOS) a point to flatten its handles. |
Channels compose in a fixed order: Red, Green and Blue curves are applied independently first; the Luma curve is applied last, to the result of the RGB curves, rescaling RGB proportionally to preserve hue/chroma rather than flattening it.
Curve points and handles cannot be modulated.
