Sorry - I hadn't read this post when I sent the previous message.

Perhaps you are over-sharpening?  Also, are you sharpening just the
Lightness channel or also the color channels?

Yes, I realized after I typed that what I actually do is resize the
TIFF, edit,  * sharpen * and THEN go to JPEG.  It's in this resized
TIFF that I see the increased sharpening or USM effects, over the raw
intitial file.
