I have never used DeNoise AI, low-light, ever, even on my photos taken in low light.
I tried to find a help file or some explanation on the Topaz website of what, exactly “Low-Light” is supposed to do, and it isn’t mentioned ANYWHERE. And I noticed that there is NO help file, at all for Denoise AI.
I tried it on some old, digitized film photos (due to complaints on DPR), and with low light ORFs and some old Canon 4mp jpgs.
I have to agree with the complainers on DPR, it doesn’t do much with any of those sorts of photos, and certainly it is NOT as good as the regular DeNoise and AIClear options. Some guidance on what it is SUPPOSED to do would be helpful in allowing us to judge its effectiveness.
