This filter generates halo maps internally for dark and light edge haloes, and uses them to sharpen the inputs. This is a nice tool to help scanned materials "pop" a bit more, and to get a more dynamic roughness map for example.
Assets used to show the filter on are 3d scans from Quixel Megascans.
Based on the implementation by Gerald Bakker and the book Modern Photoshop Color Workflow by Dan Margulis.
