I've been working with the nextphoto model trying to get an extreme closeup like, well, like this. Upscaled with ERSGAN.
Not bad. Very studio quality if that's what you're looking for. Considering it's nextphoto I'm a bit underwhelmed actually. I've used it and it normally does a great job at adding imperfections in the skin that keep people from looking airbrushed. What prompts did you use?
