I'm sure some of you have seen this before, but I'll bet many haven't. I ran across it a while back and have been using it for a while now. While more involved than simple USM, it does have several advantages, in that it doesn't add sharpening to blank areas like sky. This means less artifacts and better images. For those who want to try it, the proceddure is here: http://www.bythom.com/sharpening.htm I don't use it all the time and there are variations of this, but there are times when it really helps.
