The footage is bad I agree, particularly the last clip, I don't know how I let it go out looking like that. But that said, people talk the same bullshit when 4K oversampled from 6K is said to be appreciably sharper than the native 4K itself. They see THAT difference, but when it comes to actual...

Hi Phil, I shot the 8K/60 fps video Zack referenced here. Although it is not represented as a controlled test, I own the cameras and the land they were shot from. Both cameras have similar LoD at 7680 x 4320, the U12K scaled from 12288 x 6480, The Z8 scaled from 8256 x 4644. As mentioned in the...

It's an unimpressive number but I seem able to do the same things with it in Resolve.

I have a few higher resolution cameras, UMP12K, P6K, F55, GH5s and just added Nikon Z8. At various times I've tested most of them with Imatest. Imatest supports resolution testing with a couple of methods, edge profile and SFR MTF50. Its design goal is for lens testing. If you use one camera...

The first thing to note is that the Venice 2 image was supplied by Sony, and that the independent testers were not able to achieve a similar result. Moreover, the MTF50 graph shows a remarkable (and suspicious) ability to resolve well beyond the sensor's Nyquist, (about 7,200 LW/PH) which is not...

Rayleigh's criterion: Aperture diffraction places a limit on the smallest spot of light that can be focused on an image plane. An Airy disc refers to the central spot of light surrounded by concentric rings that are produced when a point source of light is imaged through a circular aperture...
