Just took a quick shot at the Lightroom AI noise reduction, in comparison with the Topaz (last version I think) that I have. Left is LR, right is Topaz. Bottom is LR is usual post processing.
Source image is a O-M1 file ISO 2500 with a touch of motion blur.
Still waiting for a sale on the PhotoLab 6 so I could try the DeepPrime also.
