High Pass Sharpening Method for Photoshop

Process your photo as you normally would, except for sharpening.
Convert it to 8 bit.
Go to the Layers Window, click the Background Layer, and create a duplicate layer
(Layer/Duplicate Layer). Name this layer "Sharpening."
Making sure the Sharpening Layer is selected, go to Filters/Other/High Pass. Select a radius
under 10 (8 is a good number to try) and click OK. Your photo will look gray, but
don't worry about it.
Return to the Layers Window and select the Sharpening Layer. Change the setting from Normal to
Soft Light. At this point the photo will probably look a little too sharp.
Change the Opacity to something under 70%. Experiment until you find the look you like.
