"Use this trick: select the some non camera layers,content click on one of them,and select Transform>Auto Orient from the popup menu.Select Orient Towards Camera and click OK.All of the layers will now twist so that they face the camera.Move the camera around and watch the layers follow.The benefit of this is that by viewing the layers face - on ,they always keep their perspective,rather than looking odd whenever you view them at an angle.
The second trick is having a camera auto-orient along an animation path.With the camera still selected,open its Auto-Orientation dialog,choose Orient Along Path,and click OK.You may need to smooth out your motion path to avoid motion sickness."
