Crisp existing detail without inventing new detail

Sharpening increases local edge contrast. It can make a reasonably focused image look crisper, especially after resizing.

It cannot reverse motion blur, restore missing focus, upscale with AI, or guarantee recovered detail. Strong settings may emphasize noise and halos.
