Really good article on an interesting sharpening technique. I'm about half way through it but its already given me a few ideas:

Good info. Sharpening in LAB has been a trick for some time now. The advantage is you can sharpen "just" the Luminance channel which gives good sharpness with less artifacts.

Just keep in mind, final "output" sharpening should be one of the last steps you do before output because the more times you "convert" between color spaces (AdobeRGB to sRGB for example) or color modes (RGB to LAB for example), you will loose a slight amount of image data through the conversion. Although VERY slight in most cases, you can experience extreme changes when going between some modes/spaces which is not recoverable after the fact.
