zet de eerste twee sliders zo hoog mogelijk zonder dat je overscherping of ruis creëert. de derde dient als treshold.
Een beetje uitleg:
. I always tell people it's not unsharp mask, it's mask unsharp. You are doing a blur and then masking the unsharp pixels. Subtract that mask layer back out of the image, and you've done a very complex image transform, it heightens contrast only along the edges and tonal transitions that are most suceptible to degradation from blur. It sharpens and increases contrast only where it is needed. That's what confuses people, they think it's an unsharp mask, so it unsharpens. Like I said, you're masking out the unsharp.
