The camera will aim for 18% gray independently, meaning if you take a photo of an entirely white surface, and an entirely black surface you should get two identical images which both are gray (at least in theory). It simply measures the amount of light that comes in, and makes a guess based on that. The exposure meter in the camera does not know whether the subject itself is bright or not. A Macbeth chart helps with calibrating back into a photographic capture into this “human perspective” of the world. We are biased to perceive more information in the dark and contrast areas. The human eye perceives half scene brightness not as 50% of the present energy (linear nature values) but as 18% of the overall brightness.
