Auto Exposure in VFB 2.0 automatically adjusts the brightness of your render. Instead of changing settings like ISO, f-stop, and shutter speed yourself, Corona looks at the lighting in your scene and sets these values for balanced exposure. The strength of this effect can be controlled by the value of the slider. It also can be applied to the Simple Exposure in the Tone Mapping using the Bake.
Calculates optimal exposure based on rendered values without tone mapping. To see what exposure values is generated, remove exposure operator(s) in tone mapping and bake auto exposure into tone mapping.
