I like freckles. I really do. I've been generating lots of pictures this last year, and this is one of the latest. Generated with the brand new SDXL.

However, as always happens, when rescaling or processing the face in any way, the face is smoother. Usually I don't complain, but dealing with freckles is another topic. Same with wrinkles, peach fuss, etc. That's... authenticity. So If I generate a picture with all that beautiful imperfections, I'd like to keep them. But how?

Also, light color eyes seems to get darker with every rescaling.
