How do I Change display view with character motion

I'm basically trying to figure out how to pull off the effect Whale Trail does. The screen zooms in with the Whale falls and zooms out when she goes up. thanks.

I'm not really familiar with it, but I've seen alot of people recomend a specific camera plugin that allows zoom and some other stuff. Have a look at the plugins section. I can't tell you for sure which one it is. But you might find something usefull
