I had another play with krea.ai today. This time, I thought I would be kind and feed it a much easier starting point. I tried various options and this was my favourite but it entirely fails to convey my likeness. On the surface, it does look like a decent painting of a double bassist but weirdness in areas like the fingers and wrists opens up the uncanny valley (the way humans are good at perceiving images of fake humans). I think I did a better job myself with my digital darkroom work back when I originally took it.
