Hi, Not sure what is going on here as worked fine before but after sending to Denoise on return to Lightroom there does not seem to be any change in the noise, this image was 10,000 ISO and severe option chosen, not the first image to be returned without change.
Lightroom as a TIFF, W/B, Highlights down, Shadow’s up and that is it, no cropping, latest release of Denoise, Win 10, 16 GB RAM, 64-bit operating system, Graphics Geforce GTX 1050TI.
Worked fine before updated 3.2
I just uninstalled and reinstalled Denoise. I also upgraded my On1 photo raw software to 2022 and that allows a none broken workflow (all done in one application) finding there is not a great difference in the final result as far as noise goes between Topaz and On1 Russ.
