Frequently Asked Questions

Can sharpening fix a very blurry photo?

Sharpening enhances detail and edge contrast but cannot recover information lost due to heavy motion blur or extreme out-of-focus blur. It works best on slightly soft images.

Can over-sharpening damage an image?

Yes. Excessive sharpening creates "halos" around edges and amplifies noise. Use moderate settings and check the preview carefully.
