Preliminary exercise: Continuity task involving filming and editing a character opening a door, crossing a room and sitting down in a chair opposite another character, with whom she/he then exchanges a couple of lines of dialogue. This task should demonstrate match on action, shot/reverse shot and the 180-degree rule.
Match on Action- connects two shots cut together by having a character finish an action in the second shot begun in the first shot. For instance, if a character lights a match in the first shot, the same character will draw it up to a cigarette in the second.
Shot/Reverse Shot- After an establishing shot, the shot-reverse shot refers to the close-ups used when two characters are in conversation. (Because we have already used an establishing shot, we now know where the characters are in relation to one another.) First both of the actors engaged in a conversation are shown in a two-shot then the camera cuts in to mid shots and close-ups of one actor and then the other, usually from a position 'over the shoulder' of the other actor.
180-degree rule-The 180° rule is a basic guideline in film making that states that two characters (or other elements) in the same scene should always have the same left/right relationship to each other. If the camera passes over the imaginary axis connecting the two subjects, it is called crossing the line.
