I think I finally found the perfect use-case for pixel-shift super-resolution: scanning film.

✓ Subject is immobile, so no motion artifacts
✓ On a 24MP sensor, most film grain is larger than sensor noise after merging, so sensor noise essentially vanishes once downscaled

Here's two scans of the same frame, first done on the lab using a Noritsu professional scanner, and the second done using my Nikon Z6 III pixel-shift mode, then downscaled.

top floors and cap of a city building, lit from the side by the setting sun, casting it in a faint red-ish glow. in the background, mountains are visible, with puffy clouds above, also shining with the same orange-red cast of the sunset.

compared to the previous shot, it is noticeably sharper, and the digital noise, albeit still present, seems more controlled and more pleasing (subjective)
