I´ve downloaded the demo in my search for a program to remove noise from my pictures, most of the pictures are downloaded from webpages and are of low resolution and quality (for obvious reasons ).
NeatImage is great for removing noise but removing jpeg artifacts seems to be just a welcome side effect and for that i use Image Dokter(for now).
The only problem is that i use Paint Shop Pro and there seems to be no plugin for that program.
Because my pictures are of low resolution it is important that i dont lose any more information, but de demo only saves in jpeg. I found out, well more reinvented the PrintScreen button ,for pictures up to 800x600 i just press PrintScreen in the Output Image section and paste the picture in Paint Shop Pro.
As you can see, im a real hacker.
Seriously, a really great program.
