Topaz Photo AI [v1.x.x] on [Windows/Mac]

That’s been an issue I’ve noticed on the last few releases, including Denoise AI, especially when using it on Monochrome/greyscale images. I just turn down the Red/Magenta Saturation. Sometimes I see a blue or green saturation as well. So I have to turn down the saturation on all 3 colors on a monochrome image. Not sure why these colors are being introduced on a 100% grayscale/monochrome image.

@jsiatczy-62766 thanks for reaching out.

The pink artifacts with RAW Remove Noise Normal is a known bug we’re working on fixing for a future release coming soon.

In the meantime, if you use the Strong model or increase the strength using the slider in the Normal model, the artifacts seem to go away for most users.
