Can the Human Eye See 8K Resolution? (Does Having an 8K TV or Camera Matter?)

Have you ever heard someone say that the human eye can’t tell the difference between 4k and 8k? If that’s the case, does having an 8k-capable camera even matter? And is the rumor that you can’t tell the difference even true? And, even more questions: Do we even have a use case for an 8k video, beyond buying a wildly expensive 8k TV or projector? And is buying that 8k TV a waste of money? First of all, there is another use case. Apple Vision Pro: 4k per eye with 8k total resolution. If Apple is doing it, is that a sign that 8k video matters? Before I tell you whether you can spot 8k, let’s get into what the human eye is capable of. Our eyes have an angle of view of around 180°, a focal length of 22mm, an aperture size of about F/3.2, and a light sensitivity of about ISO 800, which matches base ISO for many cameras. Our eyes are wonderful, and incredibly powerful. And TECHNICALLY they can spot the difference between 4k and 8k, but there’s a HUGE caveat: the size of the screen affects our ability to see the maximum resolution. For example, to see 4K resolution, you'd need to sit 10 feet away from a 120-inch screen, but to see 8K resolution, you'd need to sit 10 feet away from a 280-inch screen. That’s a little over 23 feet. But you have to be THAT close to tell the difference. So…yes, you can tell the difference, but not in circumstances that really matter, because none of us are rolling with a 15-foot 4k TV or a 23-foot 8k TV. The one time it matters actually circles back to Apple’s Vision Pro. When the screen is THIS big and THIS close to your eye, 4k matters. And 8k if you factor in both eyes. So you don’t need an 8k camera unless you’re filming for VR devices, or if you want the flexibility to crop into your image and maintain 4k resolution. #4k #8k #resolution #humaneye #tv #move #movies #tvs #television #applevisionpro #visionpro #ar #vr #film #camera #camera #camcorder #camcorders
