When the bloom effect came out, there also came with it that auto-light scaler for how bright or how dark the scene comes. I suggested it before but it was over in DRD team and now that it's closed, I feel it should be brought up again.
I think there should be switches for the exposure and things, I can't remember what it is. It's for the mechanic that darkens the screen when too bright, and lightens the screen when too dark.
Ultimately I'd very much appreciate a kill switch that resets the exposure to its base and never changes again when the kill switch is on.
Specifically, in the menu. While it's useful, dpJudas, sometimes there are maps where you just can't have it getting in the way. Ghoul's Forest 3 in particular is one that affects the difficulty and makes it easier.
