Apply a low pass filter (for example, a Gaussian blur) to the image, while controlling the output contrast and saturation.

This module is primarily intended to be used in combination with a blend mode. For example, try using the local contrast mask preset with the overlay blend mode.

The blur algorithm to use:
  • gaussian blur: Blur all image channels (L, a, b)
  • bilateral filter: Blur the L channel only, while preserving edges
Higher absolute values increase contrast. Lower absolute values reduce contrast. Negative values result in an inverted negative image. A value of zero leads to a neutral plane.
Negative values darken the image. Positive values lighten the image.
The color saturation. Negative values result in complementary colors by inverting the a/b channels. Higher absolute values increase color saturation. Lower absolute values reduce color saturation. A value of zero fully desaturates the image.
