Not sure the point of downscaling 4K77 to 720p… not exactly a fair comparison.
This is a 4K83 comparison, but upscaling Despecialized to 4K works too – but it’s still not a fair comparison.
Left is Despecialized, right is 4K83.
Projection prints simply have less fine detail than negatives and interpositives, no matter what resolution you scan them at.
I’m well aware of the quality of a projection print LOL. The point is downscaling 4K77 in the prior comparison makes it look far less sharp than it actually is, nevermind fine detail.
