I have been reading about SS because GIMP now has a plug-in for it. I suspect high-res LCD monitors have changed the art of sharpening. Many of the online tutorials seem to make an image worse after sharpening, I find. Maybe the images are improved on a CRT monitor, but CRTs are rare now. Of course sharpening is useful for printing, but that is not what interests me now. It is stated in several places that Remove > Gaussian Blur is similar to USM, so people do not recommend it; they use Remove > Lens Blur instead. Do you agree? I really cannot see much difference between them, except that Gaussian Blur seems a bit stronger. That is, Gaussian Blur 90% = Lens Blur 100%. The Remove > Motion Blur option does not seem to work in CS2. Did it start working in later versions? (Over a year ago I posted about this and FocusMagic, which does work.) Does Smart Sharpen have a threshold function as in USM? I find threshold very useful, but I do not see an option for it in CS2.
