Local Contrast

This script uses specific parameters of the "Unsharp Mask" filter to increase the local contrast.

By default, the script runs in silent mode. If you want to customize the filter settings hold down [Ctrl] while starting the script.

As result you get two layers allowing you to handle "lightening" and "darkening" aspects of the image contrast individually.

For example, if you find the overall image too bright, reduce the opacity of the "Local Contrast (Lighten)" layer.

Or, if you noticed too dark spots, click on the mask thumbnail of the "Local Contrast (Darken)" layer and paint over the corresponding areas with black color (screenshot).
