Medium shot

A shot that frames actors, normally from the waist up. The medium shot can be used to focus attention on an interaction between two actors, such as a struggle, debate, or embrace. Such as:

The Bridge/Bron _ Saga

Over-the-shoulder shot

A shot of one actor taken from over the shoulder of another actor. An over-the-shoulder shot is used when two characters are interacting face-to-face. Filming over an actor's shoulder focuses the audience's attention on one actor at a time in a conversation, rather than on both.  "Carol"
