I'm editing my night shots in Lightroom and use Google Nik Collection Dfine2 to reduce the noise.. Noise reducing in Dfine is the last item in my workflow, and when I export image .jpg it has poor quality, I tried exporting without noise reduction (Dfine2) and quality is better.. So what is the problem? Can I somehow export with high quality Noise Reduced image? enter image description hereenter image description here

    \$\begingroup\$ That looks more like color banding due to lower bit-depth and jpeg compression than noise. Such banding often looks very similar to chrominance noise. \$\endgroup\$

Increase the JPEG quality when you export so that it isn't as heavily compressed and the issue should be minimized.
