Real Camera is an add-on that allows you to control the Blender camera like a real camera. From version 3.0 it works only in Blender 2.8.

We finally added real time Auto Exposure for Eevee and Cycles, this feature is like eye adaptation on other render engines like Unreal Engine.
- Auto Exposure automatically adjusts the exposure (brightness) of the scene based on sampled pixels luminosity like a real world camera.
- Auto Focus automatically sets the focus point based on the center of the camera.
