Tunnel Vision
Another camera problem can occur when the player is moving through tight environments like caves, sewers, or dungeons. Low ceilings, narrow passageways, and doorways can cause all sorts of trouble to the camera.
I find that if you restrict the movement using a rail camera in these troublesome locations, you not only alleviate any camera problems but also help maintain the feeling of claustrophobia. Avoid low angles; instead, keep the camera at the character’s shoulder height or slightly above the player—but watch out for low-hanging stalactites that will cause camera sorting issues.
