Interesting. 4K is mostly a lie.

The Biggest Mistake in the History of Hollywood

@Gargron the fact that a movie theater projected 35mm prints at, best case scenario, 2K and now we scoff at anything below 4K for home video never ceases to bewilder me.

@vpermar @Gargron 35mm film, depending on ISO and lighting, was supposed to be much more detailed than that.

I can attest that when I first saw digital projection (Planet of the Apes, some fancy cinema in New York, 2001), far from being the clear sharp perfect image it was promoted to be, I found it quite dull looking and low resolution compared to what I was used to.

@mossman @vpermar @Gargron

The video says 35mm is basically at about 4k, with a minority arguing it might go up to 6k.
