Curves

Remap tones with master and RGB curves for fine exposure and colour control.

Tone curves are the darkroom and finishing language for remapping brightness. A master curve reshapes exposure; separate RGB curves tint shadows and highlights independently.

They reward small moves. A gentle S adds polish; a hard kink posters the midtones.
