You are assuming that people keep their heads static whilst they are watching which is not true. If you move your head you'll see any subset of that 8k picture which makes it more "real" to the viewer.
- tigershark 8y agoHow moving your head increases the maximum resolution of your fovea?
- conanthe 8y agoIt is not but you'll see different image depending on your eyes position when looking at higher resolution image. Think of it as 8k image resampled to 4k but at different offsets. You'll effectively see more detail when moving your head than looking at 4k image.
- conanthe 8y agoWhy downvotes? It is essentially the same thing when you can read plates from a low resolution movie where on a single frame you can see indecipherable number of pixels but if you combine the pixels from multiple frames and recover the car's offset you can compose higher resolution picture of the plates effectively being able to read them.
- blattimwind 8y agoSome speculate that microsaccades actually increase resolution and perceivable detail in static scenes by basically offsetting the retina a tiny bit. The concept definitely works and is used in practice to boost the resolution of digital image sensors ("superresolution").
