How can i make my camera rotate/move relative to my players rotation?

So what i am trying to go for is the camera system in silent hill 2 when in open areas. It doesn't just stick behind the player in the hierarchy i think.

The camera will move slightly to face the players direction, just a nudge so that you see a bit of what the character is seeing.

The camera will stay still if the player isn't facing it directly, but if the player is facing its direction it will slowly turn to its original position behind the player.

Also if you could point me to any dolly camera stuff where the camera will move depending on the players position on screen that'd be great too.

Thanks
