Compression

To capture physical environments human beings have sensors like eyes and ears. Whereas ears are acoustic omnidirectional sensors, the eye is a directional visual sensor, which collects lightNrays from one direction (head and eyeball position and rotation) and focus to a specific distance (lens). The visual dynamic range in real world is so high, that it has to be limited by the iris to avoid overloading.
