Can someone please explain how does exposure work

The official document does not tell what exactly it is. It just assume you already know about auto exposure

There are some youtube videos, but those do not give clear explanation either.

I searched wikipedia and it seems lower EV would yield brighter scene, yet it works completely opposite way in the post processing volume setting.

Can someone give me a resource to learn about auto-exposure and eye adaptation?

I’d like to know what kind of histogram it builds and what equation does it use to modify the scene brightness.

Hello HadockAndChips,

I found this talk to be quite insightful: https://www.youtube.com/watch?v=nlbJwMoj1Dg

It discusses cameras and physical lighting units, intensities etc.
