Z7: CO 20 - Artifacts on high ISO Photos

Terry Williams

The issue has become more prominent with Capture One 20 and high ISO photos.  I use a Nikon Z7.    High ISO photos tend to have a artifacts regardless of the noise reduction settings in capture one.  I did some testing with Lightroom, DXO Photolab, Nikon Capture NX-D and Capture One 20.   

I'll attach a photo from Capture One and Nikon's Capture NX-D.   Capture One is at the default settings,  For the Capture NX-D, I set noise reduction at low.   Lightroom doesn't have the artifact issue. Photolab does a little, but easily fixed with Prime.  

The ISO is 22.8K.  Anything above 6400 ISO, the artifacts become noticeable.

    Try really bumping up the color noise reduction slider.

    Your example photos are not really showing us much.
    You need to show zoomed in a lot more.

    To echo Paul S's question, what are the artefacts?

    The NX-D image looks very soft compared to the C1 image.

    Are the samples crops at 100% resolution?

    Both output examples suggest to me that that ISO setting is only useful in cases of extreme need.
