Screen going white when looking to the floor

I have just started using UE4 but I have already come across something i don’t know how to fix:
When I look down (wich I always do because I’m trying to make a top down game) the screen slowly goes white. How can I fix this?

Looks like eye adaptation / auto exposure. You can change parameters in your camera details(post process → lens) or using postprocess volume like here

Thanks for helping me!
