Hello,
I have been enjoying Topaz DeNoise 6 but there was one little issue that was bugging me on my Windows 7 system. The presets library did not sort the various ISO presets in an order that seemed convenient to me.
Today I did some experimenting and found a solution. I tried editing the info inside the XML formatted preset files but it didn't help. Finally I realized that the presets are sorted in the Topaz GUI by their actual file names, so I edited the file names and now my preset listing are sorted in a convenient manner.
I made a pair of screen shots of the presets which I use. I hope the screen shots will be helpful to other photographers and have attached them to this message.
Thank you.
