1. Make a copy of the background layer, or the layer you want to sharpen. To do this, click on the layer in the Layers Palette, then chose Layer -> Duplicate Layer..

2. Click on the duplicated layer in the Layers Palette to make it active, then choose Filter -> Other -> High Pass. Enter 10 in the for the radius and click OK.

3. Things now look a little odd, huh. Click on the layer you adjusted with the high pass filter, then from the drop down list on the Layers Palette, select Soft Light. Magic.

4. Adjust the opacity of the high pass layer to achieve desired sharpness.
