This is extremely useful. There are lots of good textures that have unfortunate specular reflections baked right in. As a result, they are hard to make look good with your actual scene lighting.
Starting with your original texture in the upper right, this finds them and decreases or eliminates them. What you're left with is a true diffuse color map coming out of the HSV node. Then you add specular nodes to make the skin really respond to your scene lighting, instead of the lighting at the time the photo texture was taken.
The parameters need to be tweaked here and there. There is no single set of values that works perfectly for all textures.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
