Or.. perhaps, if you are unaware.. the following sharpening method mitigates some of the issues that can crop up when sharpening an image (introduction of artifacts, et al):
"The difference between high pass sharpening and most other methods of sharpening is that high pass sharpening does not actually adjust or change any pixels in your original image. Also, because high pass exists as a separate layer, you can adjust the layer's Opacity and Blending Modes to control the strength of sharpening over the entire image. You can then use masks to control where sharpening is applied within the image and to make localized changes in the strength of sharpening."
