I’m trying to work with auto exposure and other post processing effects like bloom to get this effect shown in the picture but I can’t figure it out.
If you need something more specific (link is provided), the lighting change at 0:33 from The Black Masses is what I’m trying to go for. THE BLACK MASSES - Official Gameplay Trailer (New Open World Zombie Game 2019) - YouTube

It’s just auto-exposure doing it’s thing. It will over-exposure to compensate for the lack of light in the tunnel, then under-expose to compensate for the higher amount of light. Bloom should be left at default until exposure is figured out, since the appearance of bloom can be impacted by exposure.
I personally prefer the Basic Auto Exposure that will adjust based on the center of the screen instead of a Histogram. It’s easier to control and less prone to small emissives overpowering the rest of the Histogram, plus you get the benefit of having a calibration factor that it will always try to expose for.
