When you are
filming two people talking you normally use the 'far away shot',
'medium shot' and 'close shot'.
Here is how you do it.
Far away shot When two people are talking you often
begin with a far away shot showing the two people facing each other
as they talk.
Medium shot You can film someone talking using
a medium shot by filming over the shoulder of the person who is
listening. This is called an 'over
the shoulder' shot.
Close shot When someone says something important
you can film them, or the person listening to them, close up.
