Gimp tutorial - Unsharp mask

We can’t really sharpen an image any more than it already is. If it wasn’t sharp when cap­tured, there’s nowhere the infor­ma­tion needed can come from later on. What we can do is cre­ate the illu­sion of sharp­ness by exag­ger­at­ing con­trast along edges in the image. This added con­trast makes the edges stand out more, mak­ing them appear sharper. For images des­tined for print the actual amount of sharp­en­ing required for opti­mum image qual­ity is usu­ally a lit­tle more than what looks good on the screen.
