Alan, it's a bit clunky. It does not work as a plug in or on PSD files. I save them as TIF and work on them from the desktop ICON for Topaz GP. They claim it does a million samples per pixel so it's sort of slow, even on my high end puter. I start it and go do something else for a few minutes. I don't have very many sub 50 GP images to work however so I could probably do them all and quit the trial. I have not even checked the cost yet. Also, they are a bit more crunchy than a native 50MP image. I tried different settings but I ended up using 2X uprez versus 1-1/2 which would have given enough pixels.
