Photokit just came out with a new version. Sharpening can get rather
involved there is at least one thick book devoted to it: Real World
Sharpening. They listed Bruce Fraser as the co-author with Jeff Schewe but I
don't think he wrote much of it. Very good book tho. He was a great loss to
the photo community. I always work in the three step form too and you can do
the first step in ACR.
