Upscaling old picture

The picture was terrible and parts went to colour. I’ve had no problems before. It either is better or not, but not worse.

Do you have examples of this? If so post a screenshot.

Here is the before and after. There was nothing I could change to improve it. Normally I have no problem and the program works quite well.



This is a very old issue / misbehaving (that obviously still is around).
See this thread:

The problem comes from the “remove noise” model. On such images only the “extreme” one doesn’t result in such artifacts. But in your case I think you can do without Remove noise.

(This was just a quick one and needs some work with text / faces)
