How it works
Each pixel is compared against its immediate neighbors and pushed further from their average — the standard "unsharp mask" technique. It can't recover detail that was never captured (like out-of-focus blur), but it can make edges look more defined.
Frequently asked questions
Can this fix a blurry or out-of-focus photo?
Only to a limited degree — it enhances existing edges, but can't recover detail that was never captured in the first place.
