Curves remaps tones through a curve you draw. One curve set holds five channels: master, red, green, blue and alpha. The editor's own dropdown picks which channel you're editing.
How to use it
- Select a layer and choose Effects ▸ Curves.
- Pick a channel in the curve editor.
- Add and drag points on the curve. A gentle S-curve adds contrast.
