I’m wanting to tweak the way exposure works, and I wondered if anyone knew where/if any related settings are available in the .json files. I’m having a look on my own but if someone already had an idea, I would appreciate the help. 
Edit: To be more specific, by default if you are not near light sources and looking toward them, they look bright, but if you approach they become “dim” (since your eyes would “adapt”), and I wanted to not let it dim the brightness as much.
