Shot Reverse Shot

What is shot reverse shot?

Shot reverse shot is a filming technique where one character is shown looking at another character (often off-screen) and then the other character is shown looking back at the first character. Because the characters were shown facing different directions, the audience/viewer assumes that they were looking at each other. It is a feature of a classical 'Hollywood' style editing which concentrates on shots which the eye of the spectator perseveres one continuous action. 

This picture is a perfect example of Shot reverse shot. It shows two men having a conversation of which the camera turns to face them when they are talking.
