Orbit camera for change

 One great way to signify a big change has happened to the characters is by orbiting the camera around the character. Because it's such a dramatic and apparent move, the audience clearly understands that there is a shift in our or the characters perspective. The move can also move us from one place to the other as a more dynamic establishing shot.

In the following example from ParaNorman, our perspective is that of the townsfolk, in which Norman is crazily talking to himself. Once the camera orbits around, showing a closeup of Normans eyes, it ends up the same view as before, but now we see what Norman sees. A big change in perspective that allows us to see both the views of the normal people, and that of Norman.  

 In this example from Mission Impossible 3, the camera orbits 180 degrees to move us away from the story of the girl and Ethan Hunt's relationship and progresses us into doing something about the villan. What's great about this, is that we also show one set and then orbit into another. For one, this helps sell that we are moving on and also serves as a more interesting establishing shot than a simple wide Master. The motivation of the camera move is from the background characters, otherwise the move could seem forced.

I've included the video to see the movement and the shift in perspective.
