From Canon's Tips and Techniques for EOS cameras:
Consider the use of in-camera sharpening:
If you shoot JPEGs and you wish to reduce or eliminate the need for post-processing in order to speed up your workflow, you may find that increasing the level of in-camera sharpening is effective.
Apply post-process sharpening effectively:
Canon EOS digital cameras have an anti-aliasing filter installed on the image sensor. This filter improves color rendition and practically eliminates moiré. The liability is a slight reduction of sharpness. To reduce the softening effect of the anti-aliasing filter we recommend applying an unsharp mask to the image in Adobe® Photoshop®. Although there is no such thing as a “best” setting for all applications, we suggest the following as a starting point:
Amount: 300%
Radius: 0.3 pixels
Threshold: 0 pixels
Understand that image magnification affects perceived sharpness:
When viewing images at 100% magnification, the actual image size can be as large as 4 x 6 FEET depending on the resolution of the camera. If your images are regularly printed at 8.5" x 11" or less, the equivalent magnification with EOS-1D Mark II would be approximately 33%, or 25% with an EOS-1Ds. Try printing your images to evaluate sharpness.
