> The weirdest thing in the Google presentation is that several sections had presenters talking to a different camera than facing the screen. That just felt very strange.
B-Camera angles are common in interviews. It's to help create a less formal and less stuffy 'presentation' like feel. It's intended to be more of a "you're standing there, somewhat behind the scenes" feel.
It is also one way to obscure the fact that someone's using a teleprompter because it is more difficult to see that their eyes are moving back and forth.
From what I watched of the presentation, there was also a fair bit of moving around. In my studio, we primarily used it as a way to hide main camera adjustments in the edit, usually from the interviewee changing positions, slouching, etc. Generally, a high enough quality production will never rely on a single camera regardless.
I went back and checked Apple's keynote and noticed that all their presenters faced the camera. But the camera itself was panning slightly which helped, as you said, to feel less stuffy. Nice!
