I supplied the AI with two photos: the piano keyboard (which I shot myself) and a stock image of a girl sitting on some steps. The girl looked like she was too young (maybe 16) so I told the AI to age her 10 years. It did an excellent job of that. Also the seamless integration of her into the shot of the piano keyboard, along with appropriate lighting and shadows. However, it really screwed up in other ways. It distorted the symmetry of the piano keys. It also placed her too low and too far right (I wanted her sitting on the keys, about where the E above Middle C is. Telling the AI to move her where I wanted resulted in no change to the image.
But I do like how all of the blurriness, low-resolution, and other annoying artifacts are removed from my original source photo.
