What is the difference between the actual effect of photography on the screen and the effect of people seeing the scenery?

The main difference is perspective and image field distortion. The distortion of the human eye is 0, but even the best lens will have slight distortion, especially wide angle, because the lens with different focal lengths has different viewing angles, and the human eye is equivalent to a fixed-focus lens, which will inevitably lead to differences. Color has little effect.
