How To Avoid Over Sharpening

Antarctica CLXXI
Identifying and developing a sensitivity for the artifacts digital sharpening produces will help you choose a sharpening method and what settings to use during any stage of your sharpening workflow. You can easily see the artifacts digital sharpening produces by overdoing it. Apply a filter like Unsharp Mask at maximum strength and look closely at what happens.
Following are the seven most common digital sharpening artifacts.
1. Noise
2. Exaggerated Texture
3. Visible Light Halos

4. Visible Dark Lines
5. Loss of Highlight Detail
6. Loss of Shadow Detail
7. Increased Saturation
These artifacts can be reduced in one or more ways.

If you know what to look for, you’ll know what path to choose and how far down it to go. Training your eye for what to look for and understanding the upper limits of what other people find to be naturalistic, or at least not distracting, is the first step to developing your unique sharpening style. The second step is learning how to produce certain effects and avoid others with the tools at your disposal. Once you’ve taken these steps, you can take the third and final step, knowledgeably putting craft in the service of your vision to make compelling visual statements. Enhancing detail is one area of expertise that’s well worth mastering for all photographers.
