Optimal image sharpening is best done in three stages— capture (do it during RAW conversion), creative (do it in Photoshop) and output (automate it).
Capture sharpening benefits all images. It compensates for inherent deficiencies in optical and capture systems. All lenses and sensors have specific characteristics and deficiencies. They don't all have the same characteristics or deficiencies.
To speed your workflow, default settings for a best starting point for capture sharpening can be determined for all images created with the same lens/chip combination and saved for subsequent use. To optimally sharpen an image, you'll need to modify these settings to factor in additional considerations—variances in noise (ISO, exposure duration, temperature), noise-reduction settings and the frequencies of detail (low/smooth to high/fine texture) in an image.

The goal is to enhance detail rendition without producing distracting visual artifacts. You’ll find many conflicting philosophies and their accompanying strategies for sharpening images. The seemingly conflicting advice can be hard to reconcile.
Should you sharpen once or multiple times? Should you sharpen differently for different subjects? Should you sharpen differently for different sizes? Should you sharpen differently for different presentation materials or supplies? Should you view your files at 100% or 50% screen magnification?
