Actually I was toying with the idea of using a Photoshop sharpening trick (using Avisynth instead) where you create a duplicate layer and use it as a high-pass filter. It non-destructively sharpens and looks great in photos.

It's mostly a matter of figuring out a way to do it.
One site suggested a duplicate layer that is blurred and then subtracted from the image.

Anyway, regular sharpening methods blow, so I need to do some serious net searching (unless some can give me some pointers on this).
