Yes, Topaz has really done a good job of integrating AI to this software to enlarge images without losing any details.
I have tried out the trial version software on images shot from my Canon1DX Mark ii camera and also on my smartphone. The results have come out pretty good.
It is useful for all those who are in the habit of doing big size prints.
It is really useful to me since I do bird photography. I can easily crop out the portrait shot of the bird shot at a distance and apply AI Ggapixel to get a good clean portrait image of the bird.
