About the mixed technic:
I used multiple passes of magnific.ai plus paint over with photoshop (mostly masking 3 versions). It is both exciting to process old pictures with this technology, and challenging to keep consistency in design with these AI tools. All in all, its a lot about choosing between what the software proposes from it is ordered to do. I have a weird feeling it will not be limited to picture generation, but to just about every area of future life.
