I downloaded it as I am still in the upgrade period - you get used to upgrading Topaz AI once or twice a week as they continuously improve it. For the fun of it, I ran a very noisy image I have posted elsewhere here of a bird taken at iso 20k, heavily cropped, removing the noise as you go down the images using DxO PL6 (XD noise reduction) 2; DxO PL6 (XD noise reduction) followed by Topaz Denoise 3; Photoshop AI Enhanced 5; Topaz Denoise from RAW 7. They are all pretty good but I prefer DxO XD. PS takes ages to process. I find Topaz AI pretty useful and it does have its unique upscaling facility. What's also nice about Topaz is that its Denoise works very well on jpegs whereas the other two need RAW. As a plus, it means you don't have wait a few weeks or months til a new RAW converter from DxO comes out when a new camera model is released.
