Image Sharpen Tool
Photos can look a little soft after resizing or from slight camera shake. This tool applies an unsharp mask, the same basic technique found in photo editors, to bring back edge contrast.

Frequently Asked Questions
Can sharpening fix a very blurry photo?
No. Sharpening boosts edge contrast in an image that already has some detail. It cannot recover detail that was never captured.
Why do I see bright outlines around objects?
That is over-sharpening. Lower the amount or the radius until the halos disappear.
