Hi John -
Great to hear from you again! I hope you had a nice holiday.
Sharpening is something that I have maintained an interest in for many years, so I would be very interested in pursuing this. However, to be honest, without an example, it's difficult to talk about this in the abstract.
So, would you consider posting one of your original, straight-from-the-camera raw files + what the image looks like after your r=9 USM step?
If you don't want to post the entire image for reasons of either privacy or file size, you could just post a cropped version, so long as that area contains a representative sample of some important (and some minor) edges, some areas with texture, some smooth areas, etc.
Cheers,
Tom
PS - BTW, the forum file uploader software doesn't especially like NEF, CR2, xmp, and PSD files, so if you do decide to post an example, just zip everything together. The uploading software works well with zip files.
