I have used this method, however so far I must say that I am not absolutely sure that High Pass gives better results than unsharp mask or smart sharpen,
particularly when these can be used on their own layer and opacity changed.
Goofy - That's it. I open my image in CS5, duplicate the background layer, and apply just enough high pass sharpening to tone up the edges a bit. Then I try soft light or overlay to see if I like the effect.
Think it was my explanation that was not clear! Yes the High Pass filter applied to a duplicate layer then blending and opacity adjusted as required works well.Maybe I'm not reading this correctly but when I use the High Pass filter I duplicate my original background layer, once the filter is applied the blending is changed to overlay and the opacity can be altered to taste. The High Pass is it's own layer and opacity is adjustable....Just my two cents, I don't want to start a "best way to sharpen" argument.

The point I was trying to make is that I have not seen any advantage of using High Pass over either USM, SS on its own duplicate layer or sharpening in the L of LAB - so far! There are bound to be times when one method or even a combination of methods proves to be better for a specific image. In other words the image and its final output medium (plus our experience) will dictate the method to use.
I doubt that there is a one stop solution for 'best way to sharpen'. We can only base our opinion on what works for us within the limits of our own experience and current knowledge
