So for example, if you try to capture a bright area with a camera, the other surrounding area can become too dark due to the camera “dilating” so that the bright area is not too bright, but our eyes can look at it fine.
Our eyes dilate too, but it’s not nearly as much as a camera.

Brightness range. Our eyes can percieve a wide range of brightness level, we can process an “image” where some parts are literally thousands of times brighter than others. Monitors need to compress this to 256 values from “completely black” to “completely white”. Most cheap cameras also cannot capture such a wide range, they need to lower or raise the total amount of light that gets inside them.
However, modern cameras can provide better dynamic range than monitors, some compression is already performed.
