Bezier Curves¶

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 Kurven effect that does the same thing but does not have the curve handles.

Note the extended handles on the red dot in the middle with which you can adjust the steepness of the curve leading to and leaving the point.
