I was leaving this one until the aspect ratio was addressed.
I’d heard of Gigapixel, but as a high resolution panoramic digital photo process that is actually pretty scary in how deep you can go in the images. Been around for several years now.
Another company named Topaz sort of appears to have appropriated that name for its own software for enlarging images. Haven’t had an opportunity to test drive it yet. I’m always leery of these claims, but AI is coming far fast, so this one has interested me. The reviews they’ve received are sort of what I expect though. GIGO. Back to work next week so may have some free time to run some tests.
