Lighting - Exposure and intensity units confusion

Where did you read this? This is the first I’ve heard of it.

Here are two timestamps:

Exposure Control | Tips & Tricks | Unreal Engine

If you’re talking only about light intensity, I think you’ll have to eyeball it (for the sun at least). Using a chart is probably a useful starting point though.

So understanding that intensity of atleast directional light is pretty much an eyeball, if I’m using auto exposure instead of manual in the enviroment which doesn’t have a complex lightning and doesn’t need compensation curves. is the “Exposure compensation” also an eyeball/ more of an artistic control?
