I have been using (and advocating) Topaz Denoise AI and Topaz Sharpen AI for years, and occasionally using Topaz Gigapixel AI as well.
So for me, some exciting news! These 3 programs will be combined into a single program called Topaz Photo AI, and it will be available for sale sometime in September.
To learn more about it, go to YouTube and search for 'TOPAZ PHOTO AI Dave Kelly'.
