I have an old scanned photo of an old woman which is pretty small (352 x 535 pixels). I thought it might be a good opportunity to try Topaz Gigapixel AI, which I have but never use. I first used Topaz Noise AI on it and it ended up looking pretty good.
When I loaded it into Gigapixel AI, I selected the smallest default enlargement, which was 2x. The skin of the subject ended up looking horrible, noisy and wrinkly. See before and after example. Is this typical for enlarged faces? I adjusted the sliders to try to get a better result, but failed. I can, of course, mask the facial areas to make them look better, but I wonder if there is anything else that can be done. I don’t want to post the entire photo because it isn’t mine.
