Once again, I tried Topaz Labs. They have come out with "New and improved" versions of their AI software. I coughed up the money, and 'renewed' my yearly plan (not going to renew it again, for reasons that will follow.) But I was willing to give it another shot.
I loaded an Olympus ORF file into Topaz DeNoise. It did ok, but left the image kind of dull and flat. So, I closed that, and opened Topaz Sharpen AI, opened the same ORF file. It does have a rudimentary denoise function. But the finished results again were lacking.
To use the Topaz software, you need to open them in another program, adjust exposure, then use one Topaz plugin after another. And although you can get good results, the Sharpen AI takes a long time (6 minutes).
On1 NoNoise 23: opened the same Olympus ORF file in NoNoise. Not only was I able to remove the noise, but I could also sharpen the image at the same time. And it was finished in about 30 seconds. If I want to have even more editing, I could open file in On1PhotoRaw, get it all done in about a minute.
On1 for the win, again
