Shot/Reverse shot

Definition: 

The use of three shots edited together to show both sides of a conversation or action sequence between characters.

A shot/reverse shot sequence is made up of a master shot, a shot and its reverse shot. 

Usually one character is facing to the left and the other to the right.

Uses: 

SW Typically used in most sequences of dialogue. 

A scene will be shot from three perspectives: one perspective framing both characters together (the master shot), a second shot framing only one character from the other's perspective and a third shot framing the other character from the reverse point of view.  

The scene will then be edited, using a combination of the three shots to create a logical structure.
