Thank you Developer, Topaz Denoise is a excellent software.
However, my camera is very bad, it have lots of color noise (color patch) at High ISO, which is not possible to remove by Topaz Denoise.
AI Clear are better at remove color noise than Denoise AI or Low Light mode, but it tends to oversharpening the edge and cause artifact.
It would be great, if Denoise AI can train with image contain more color noise.
Here is an example of the Raw file
