Your comment ("The human eye differs from a static image") leaves out a key variable: Human perception.

This function goes beyond a mere recording that the human optical system performs. After all, a given scene contains too much data for the human conscious awareness to take account of. Perception in effect acts like a filter to reduce the sensed data. Perception includes a reference to learned experience that helps consciousness to interpret a given scene. This experience affects the seeing process. One could say that perception biases conscious awareness. Hence, no two people will construct precisely the same mental image of a given scene.

That said, such a thing as true color exists. The subject matter of the given scene every normal human will recognize. The response to relations of forms in the given scene may vary slightly, of course. Age, education, training, and intelligence may each produce their own effect.

Yet, we could select a subject familiar to all humanity, perhaps a naked infant lying on a blanket, and then adjust exposure and coloration to mimic very closely those found in actuality. The human perception will accommodate any slight variation from actuality as portrayed, to present the manufactured image as if the real thing to human consciousness.

Interestingly, perception exerts such a powerful influence on human conscious awareness that even in a poorly lit room, the eye will assume whiteness in a given object that experience has taught as always white. Using this white reference, perception will in effect color correct the other objects in the room as their true color.

This subject could go on. And my understanding of it could improve.

The point here is that despite a given photograph offering a two-dimensional, static image, our human seeing process will give a life to the photograph and see it as if real.

It is impossible. The human eye differs from a static image, darting around while the brain constructs its image. The dynamic range of the human imaging system far exceeds any photo.

And of course what one sees is unique. Ever wonder what color blind people see?
