Whenever the camera is in an enclosed space, the lights slowly rise from wherever they are to fit a standard level. This makes things like examining emissive materials and evaluating how effective your lighting is much more difficult. Is there any way to disable that effect? This also occurs in play mode.
add a post process volume, go to lens section then auto exposure. set the min and max brightness to the same number. Also you may want to go to the post process volume settings section and check unbound so it affects your entire scene
You can do what @ThompsonN13 said on your camera too btw
