Call Auto_LCS for Luminosity-Contrast-Saturation adjustment
Apply a G’MIC anisotropic smoothing
Set-up strength and opacity according to the uiser requested level of strength

if Method = Jamac :
Step 2
Duplicate the layer and apply:
G’mic -> Details -> Simple Local Contrast (SLC);
set the following values:

set the following value:
– smoothness = 10
Set the opacity in PCS layer based on the strength requested.

Step 5
Duplicate PCS layer and invert luma

if Method = Keil :
Step 2
Duplicate the layer and apply:
G’mic -> Details -> Local Normalization (LN);
set the following values:
– defaults

Step 3
Duplicate LN layer and apply:
G’mic -> Repair -> Smooth Anisotropic (AS);
set the following values:
– amplitude = 40
– sharpness = 1
Set this AS layer in
– Soft light mode and
– Opacity between 40 and 80 %, based on the strength requested.
