I'd be curious to hear your results in experimenting with this.

Excellent article about Lab-sharpening , very interesting! Thanks! Just one thing I wonder - of course could try out myself and see, but what do you think.... Is there any difference, if I do the USM in RGB mode and then select FADE, leave it 100% but change the mode to luminosity? All the best ' Sakari Mäkelä Siuntio, Finland Hey!

As I mentioned in the article, the examples were extremely oversharpened to show the effects and differences. High pass sharpening can be great for certain types of photos. Those with higher contrast boundaries tend to produce better results with that method.

The difference between LAB sharpened and RGB sharpened is very difficult to see from the fist set of mouse-over examples. Subsequent examples showed both techniques can produce halos, which is simply result of improper radius setting. Another interesting sharpening technique is high-pass. It does not offer the wide range of control like USM but it is quite effective in many cases without increasing noise. Max Nice writeup on this topic.
