Either way, my impression – subject to my personal photos and preferences – is that DxO’s noise reduction is currently the best available as of 2023. The DeepPrime XD algorithm in DxO PhotoLab 7 is the best, while the algorithm in DxO PureRaw 3 is also very good. Topaz Denoise AI is close behind.
i wanted to try Topaz photo AI, it need to install about 42 module to be able to work. once you upload a picture you can play with and see the results, but you can’t save it, you downloaded all that just to get a preview
anyway, photo AI is to me a notch under PL, sorry topaz!
