A high pass filter.
This module is primarily intended to be used in combination with a blend mode. For example, try using the module with a blend mode of “soft light” for high pass sharpening.
Note: This module performs blurs in Lab color space, which can result in undesirable effects, and is no longer recommended. Instead, use the contrast equalizer module for fine sharpness or the local contrast module for general sharpness.
