2 suggestions Dan Margulis makes that may help:
1. Change to LAB and sharpen the L channel only; or
2. Sharpen in RGB - then "Edit - Fade Unsharp Mask - Mode: Luminosity"

| Todd,
| I have experimented with the radius setting. However, when I reduce
the
| radius enough to eliminate the halo, I do not get much sharpening. Also,
| this white line (halo, if you will) does not occur everywhere - just
certain
| areas where a black boundary is net to a light area. At least it is not
| noticeable in other areas of my images. I'll read your articles - thanks
for
| the links. Also, thanks to Les for his link.
