Yes, I did appreciate the discussion, and I picked up a few things, though
none of it really had to do with my original question, which was how might
people be using Silverfast's USM feature in combination with Photoshop's.
In my own experimentation, Silverfast USM intensity of 80-120 and threshold
of 2.0-4.0 seems to find the edges pretty well, but it can end up being too
much sharpening to permit any further refinement in Photoshop. Much less
sharpening than this in Silverfast, and it is difficult to see in the
preview. I think that the Silverfast preview for USM simply doesn't work
very well.
My conclusion is to do as you originally suggested (whether for the same
reason or not) and just not use USM in Silverfast and do it all, whether
once or twice, in Photoshop.
