Zone Control and Curves
Zone Control is ColorPerfect’s signature way to edit the tonal curve underneath the colors, using a perceptually uniform 0–100 scale. It lets you move tones where you want them without the typical color breakage that happens with ordinary RGB curves.
This section explains the zone value boxes, zone locks (control points), editing the curve overlay directly, and using Moderate to scale an entire zone edit up or down. If you want powerful tonal shaping that stays “together”, start here.
