Bézier Curves - 颜色曲线调整¶

Description

This effect is used to adjust the color levels similar to the 3-Point Balance but with finer control. Although the effect defaults to the RGB channel, it is mostly used with the Luma channel. See also the Curves - 曲线 effect that does the same thing but does not have the curve handles.

Click anywhere on the graph paper to insert a node. Use the extended handles on the node to adjust the steepness of the curve leading to and leaving the point.
