Be interesting to see an A/B comparison between this and Topaz Gigapixel AI.

Here is a comparison between Olympus pixel shift and Gigapixel
AI:

And here Gigapixel AI looks a lot better than Photoshop Super
Resolution.

However also Gigapixel AI generates fake detail. I can't find
the link anymore, but I remember another comparison where if you
looked in image areas with random detail (for instance without
geometric patterns), you could see that Gigapixel AI was just
generating fake detail.

They all generate fake detail. How can they not? The image only contains as much detail as it does. There may be "hints" of greater detail but
even "A.I." can only extrapolate so much. It's like those ridiculous scenes on police shows where they "zoom in" on a crappy video image, then
say, "can you sharpen it up?" and voila, detail magically increases 10-fold.


I've been using "Pixbim ColorSurprise AI" to convert some old family B&W
photos to color and sometimes it's amazing at the apparent increase in detail.
Unbelievable at times!
