Thanks as always, Pog. I have to admit that I still use the old Lab Overlayer most; when I have used the newer Lab Blender, it's been with either neutral or hi saturation defaults, as I just didn't master the extra control. Look forward to giving this a test ride.

It would be great if (in your spare time---hah, hah) you could add a short quickie tutorial on what each slider does and what some recommended settings in what situations are good starting points. Although I may be the only one who feels the need for that .

Yes the original Lab Overlayer did some interesting things... so interesting, and contrary to the conventional/correct math, that I've not really been able to duplicate them since!

That's always been my problem with the tools built into my various image editors... flying blind.
