It's already awesome to watch anything in 4K, but what about 8K? It will be so incredibly realistic, you'll feel that you're looking at real life instead of a show. This was demonstrated in an experimental film screened by the Japan Broadcasting Corporation (NHK).

The film is called "The Chorus". Watching it is a totally different experience.
What was immediately striking was that the image was so crisp that it was possible to distinguish the leaves on the trees in the background. Rather than making the image seem flat, the clarity gave the picture a depth hitherto unseen on digital projections. The colors were also magnificent. The whites and blacks were stunning.
After the movie screening, the tech crew gave some really interesting insight into what this technology means:
The 8K resolution covers almost the entire range of vision (induced visual field) which influences the human grasp of spatial coordinates. The pixel structure remains invisible to the unassisted eye even when viewed across a horizontal angle.

8K (Super Hi-Vision) should truly come into its own in sports coverage. In a sport such as football (soccer), for example, it is possible to view the whole pitch at once and follow the motion of the ball and every player clearly.
Read on over here. Are we ready for 8K? God knows how much this would cost you.
