Why do television studios look GIGANTIC on TV but in real life are actually very small?

Question

I have visited many television studios, and it always baffles me. How does this work and what is the art called?

Answer 1

Great care with camera angles. Wide angle lenses up close. Never show the boundaries, giving the impression that there is much more beyond what you see, rather than just a little more. Show the same scene from different angles. The TV screen already looks like just a window onto a scene. That window doesn't let you know how much there is outside of its field of view.

Answer 2

I am not sure what the art is called but I know its all about camera angles and stage props. The camera men always show only a portion of the audience, then they will show like the same people from different perspective... making it seem like there are more people in the audience than whats actually there. They always dim the background and sometimes even use mirrors... all so you can never tell where the audience stops.
These are some of the things I notice when I sit in a studio audience. I think the key secret is to never show all the studio at once.
