The KPT series has always been popular. I dunno, I never really use filters except a few native ones like the standard unsharp mask and whatnot. I did win Aurora from www.digi-element.com last year, and for all the bitching i gave trying to get it to install properly, I still haven't used it... it does looks really cool though. When I scan some negatives I'll be making some use out of it for sure... http://www.nikmultimedia.com/usa/products/samples/all_samples/samples_nikefex.shtml the above company also makes some killer tools, check them out.
