Anyway, I do like the Clarify feature...it's simple to use and you don't get lost in the minutiae of fiddling with a host of controls.
From the brief amount of research I did last night, it appears that even Jasc is a bit tight lipped about what exactly that function does, which I'm not exactly a fan of. Call me a control freak, but I like to know exactly what 'all-in-one' type functions do.
It's all good, though; it appears that it just works, which is nice. I was able to achieve a similar effect in PSE with contrast and lightness controls. It certainly wasn't one button, but it wasn't a painful series of doo-dads either.
