LabTools - Tweak your image in Lab space

by Roland65

[This plugin was renamed from SContrast to LabTools]

This plugin allows to increase or decrease the image contrast by applying an S-shape curve to the Lab L channel.

It also allows to increase or decrease the saturation level by modifying the slope of the Lab a and b channels.

The plugin effect is controlled using three parameters:

  • Contrast: increase or decrease the image contrast
  • Lightness: increase or decrease the image lightness
  • Saturation: increase or decrease the image stauration

Note that, due to the nonlinear transformation used, the lightness effect depends on the contrast level value.
