Had a photo without too much noise in LR but not sharp enough. when I brought it into Topaz Photo AI, when it sharpened it, there was a lot of color noise. So I turned on “Remove noise”. When it was done I noticed it added a big black splotch (?) to the photo. All the settings applied in Topaz PAI were automatically determined, except that I turned on Remove Noise, which wasn’t on by “analysis”.
Splotch is just above mainland on the left lower side.
