DxO PhotoLab is not replacing ACDSee. It is the same as Topaz Denoise AI but does a bit more. You choose how much more you want it to be. It can be only a denoising tool, and I use it like that.ACDSee handles. Linear adng just fine! If ACDSee handles all my pp just fine, with the possible exception of denoising, WHY would i choose to replace it wit something else? I am bewildered by DXO users seem unwilling to accept that people could prefer something else.
Again, it is not DxO PhotoLab vs. ACDSee, but Topaz Denoise Ai vs. DxO PhotoLab.
Since ACDSee handles linear DNGs, you get even more benefits from DxO PhotoLab vs. Topaz.
