Recently, I mentioned a few programs in a comment. Program relating to reducing noise in photographs.
Those programs were Lightroom CC, DxO PhotoLab 3, DxO Nik Collection 2.5 (Dfine 2), and Topaz DeNoise AI, Topaz Sharpen AI.
It should go without saying that I have no financial, personal, or emotional investment or stake in any of these products. I own them all, but most have free trials for anyone interested.
This post aims for a quick comparison between the tools using this photo (as shot, no adjustments)
