The second advantage is a preview function which shows the effect of sharpening as a function of sharpening strength - you have to see it to get the idea. this is a grey scale display which shows the edges of the image being sharpened - this is an excellent QC tool for avoiding the luminous edges often caused by oversharpening. It's not quite as much of a black-box as unsharp mask The third is the extreme sensitivity - the sharpening really snaps, and is controlled by only 2 sliders. In addition it's very effective, fast and it's free. Douglas I'll have to get around to making a little gallery showing and comparing freeware/shareware/cheapware/ and can't-be-done-without-ware one of these days :-) There's some clever stuff around, and it's not all expensive.
