Adjust Brightness Screen

Hello everyone,

I was wondering if anyone knew how to make one of those Adjust Brightness screens that you see in a lot of games, specifically horror games. I figure I have to use a slider, but I am not quite sure what I am adjusting. Something in Post Processing maybe?
Also not sure exactly how to set up the image that is supposed to show.

If you don’t know what I mean, here is an example:

Simple LUT Adjuster | Fullscreen & Camera Effects | Unity Asset Store this free asset helped me make my brightness settings, it has a bunch of camera effects that can be accessed from scripts and that includes brightness.

May be it helps you.
