In dark areas, there is a repeating square artifact when upscaling. I re-ran the same noise/sharpening settings without upscaling, and the artifact was gone. Happy to provide test images upon request. Topaz Photo AI 1.5.0. Ruined an astrophotography enlargement I was having made… It is fairly subtle, but very present on large areas.
Thanks for reaching out. Please send the following information so I can try to reproduce this.
The original image file.
The processed image.
A screenshot or description of the settings panel so I can see what adjustments were turned on.
