      Wasn’t normal 35mm film about the equivalent of somewhere between 4k and 8k depending on the film stock?

      Plus, the projector optics will always limit the sharpness of the picture. No lense is ideal, and even ideal lenses would have fundamental limitations due to diffraction.

        Something like that.

        As far as lens optics, we’re really splitting hairs here. 70mm through a quality lens in an imax theater is going to look absolutely fantastic and stunning. Digital is just more convenient and at some point it will catch up and surpass film.

          My point was more like that even IMAX film doesn’t quite get to 18k equivalent, more like 12 to 16k. Honestly, anything above 4k (for normal widescreen content) even on big screens is barely noticeable if noticeable at all. THX recommends that the screen should cover 40° of your FOV; IMAX is what, 70°, so 8k for it is already good enough. Extra resolution is not useful if human eye can’t tell the difference; it just gets to the meaningless bragging rights territory like 192 kHz audio and DAC-s with 140 dB+ S/N ratio. Contrast, black levels, shadow details, color accuracy are IMO more important than raw resolution at which modern 8k cameras are good enough and 16k digital cameras will be more than plenty.

      I don’t think there’s any reason we couldn’t make a store 18k video.

      And we could make screen at much higher resolutions that that at imax size, or even quite a bit smaller, though I suspect it would be absurdly expensive.

        Storing it isn’t the problem, you’ll still need to be able to record and project at that resolution.

          As I said I’m sure we could make screens that could do that. They would be absurdly expensive and heavy and stupid, but it could be done. Not worth it though.

          And it looks like at least 16k cameras have been made.

            The screens aren’t the problem. It’s often the hardware driving it. The current top generation of gaming gpus struggles at 8k. There’s very little chance of being able to render and play 16/18k

        proprietary technology

        Not like the off the shelf stuff you can get to store and show 18K.
