Compositing node
Curves
Draggable tone curves for the combined RGB channel plus red, green, and blue individually — the precise, hands-on way to push contrast or introduce a color cast exactly where you want it.

What it does
Curves is a compositing node: it layers, masks and routes pictures. It takes picture in and gives picture out.
Try it
Pull an S-curve on the RGB channel to punch up contrast on flat, washed-out noise textures.

Controls
Every control with a range can be driven by a modulator, a note, an audio level or a sketch.
| Control | Range or options | Default |
|---|---|---|
| channel | RGB, Red, Green, Blue | 0 |
