Help with changes on up date

Hello, I have just updated to the new UE4 and now have this weird this of not seeing detail when looking out of a cave i have built.
if im inside the cave looking out everything looks black other than the daylight at the end of the cave. if i turn to look into the cave its all black and slowly starts becoming light. I light the effect but not when im building the cave. how can i turn if off???

That’s eye adaptation, adjust your exposure settings in the Post Process volume
