Shot/reverse shot

Shot reverse shot is a continuity editing technique used in conversations or simply characters looking at each other or objects.

A shot showing what the character is supposedly looking at (either a point of view or over the shoulder shot) is followed by a reverse angle show of the character themselves looking at it, or of the other character looking back at them, for example.

Shot reverse shot often ties in with the 180 rule to retain continuity by not distorting the audience's sense of location of the characters in the shots.
