When I had the Trial version, Topaz's own Noise Reduction program (or sub-program) was something you could decide to include or not and, when you included it, It would extend the processing time by quite a lot. It worked extremely well, too. Now I've got the full program, paid for, version 2.4, there's no separate option for its own noise reduction, it takes less time and, I'm fairly sure, isn't as effective. Anybody else think this?
