I thought it was very unlikely that it would, but now we're sure.Įxported from LR, without any sharpening (slider at zero in the converter, none in the export dialog) I'll find an image from myself that shows the same effect and do the same.Įdit: just did, but I processed an image to about the same size as yours from Lightroom, it gave very similar artifacts in Sharpen AI along the blue sky top border. I'd say it's a bug and I would report it to Topaz. What is strange that if you enlarge to 400% and just look at the processed preview of a small area the worst artifact is always in the right top corner of the preview, irrespective of where exactly you are in the image along the top border.Īnd in your original file I can't see anything (not even a hint) of slightly different colour blue pixels that the program might mistake for detail that needs to be brought out.

Click to expand.I downloaded your original image and ran it like you did and get exactly the same result, I varied the top two sliders ('Remove Blur' and 'Suppress Noise') a bit but again the problem persists.
