What Happens When The Cameras Shoot From Both Sides Of The Motion Vector Line?

Principle in filmmaking

This schematic shows the axis between two characters and the 180° arc on which cameras may be positioned (green). When cut from the green arc to the red arc, the characters switch places on the screen.

In filmmaking, the 180-degree rule ^[1] is a basic guideline regarding the on-screen spatial relationship between a character and some other character or object inside a scene. The rule states that the camera should be kept on one side of an imaginary centrality betwixt two characters, so that the first character is always frame right of the second character. Moving the photographic camera over the axis is called jumping the line or crossing the line; breaking the 180-degree rule by shooting on all sides is known as shooting in the circular.

The 180-degree rule enables the audience to visually connect with unseen movement happening around and behind the immediate field of study and is particularly of import in the narration of boxing scenes.

Examples [edit]

In a dialogue scene betwixt two characters, a straight line tin be imagined running through the two characters. If the camera remains on 1 side of this line, the spatial relationship between the 2 characters will be consistent from shot to shot. Shifting to the other side of the characters on a cut will reverse the lodge of the characters from left to right and may disorient the audition.

The dominion as well applies to the motility of a character every bit the "line" created by the path of the character. For instance, if a graphic symbol is walking in a leftward management and is to exist picked upwards past another photographic camera, the character must get out the first shot on frame left and enter the next shot frame right.

A jump cutting tin exist used to denote time. If a graphic symbol leaves the frame on the left side and enters the frame on the left in a different location, it tin can give the illusion of an extended amount of fourth dimension passing.

Another case could exist a car chase: If a vehicle leaves the right side of the frame in 1 shot, it should enter from the left side of the frame in the next shot. Leaving from the right and entering from the right creates a similar sense of disorientation as in the dialogue example.

Contrary cuts [edit]

The imaginary line allows viewers to orient themselves with the position and management of activity in a scene. If a shot following an earlier shot in a sequence is located on the opposite side of the 180-degree line, and so it is chosen a "reverse cut". Reverse cuts disorient the viewer by presenting an opposing viewpoint of the action in a scene and consequently altering the perspective of the activeness and the spatial orientation established in the original shot.^[2]

There are a diverseness of ways to avoid confusion related to crossing the line due to particular situations acquired past deportment or situations in a scene that would necessitate breaking the 180-degree line. The movement in the scene can be altered, or cameras prepare on one side of the scene so that all the shots reverberate the view from that side of the 180-degree line.^[2]

Another way to allow for crossing the line is to have several shots with the camera arching from 1 side of the line to the other during the scene. That shot can be used to orient the audience to the fact that they are looking at the scene from another bending. In the example of movement, if a character is seen walking into frame from backside on the left side walking towards a building corner on the right, equally they walk effectually the corner of the edifice, the camera tin catch them coming towards the camera on the other side of the building entering the frame from the left side and then walk straight at the photographic camera then exit the left side of the frame.

To minimize the "jolt" between shots in a sequence on either sides of the 180-degree line, a buffer shot tin can be included along the 180-degree line separating each side. This lets the viewer visually comprehend the change in viewpoint expressed in the sequence.^[2]

Style [edit]

In The Shining, Stanley Kubrick shoots broad shots from both directions, a 180-degree flip, crossing the line.^[3]

In professional productions, the practical 180-degree dominion is an essential element for a manner of moving picture editing called continuity editing. The rule is not ever obeyed. Sometimes a filmmaker purposely breaks the line of action to create disorientation. Carl Theodor Dreyer did this in The Passion of Joan of Arc; Stanley Kubrick also did this, for case, in the bathroom scene in The Shining.^[4] Directors Jacques Demy, Tinto Brass, Yasujirō Ozu, Wong Kar-wai, and Jacques Tati accept also ignored this rule sometimes,^[v] as has Lars von Trier in Antichrist.^[6] In the seminal French New Wave film À bout de souffle (Breathless), Jean-Luc Godard breaks the dominion in the starting time five minutes in a car scene which jumps between the front end and dorsum seats, improvising an "aesthetic rebellion" for which the New Wave would become known.^[vii] When the rule is broken accidentally, or for a technical reason (such every bit the inability to place a camera physically in the correct position), there are techniques which may be employed to endeavour to hibernate the fault. For example, the editor may pre-lap a discussion or two of dialog prior to the cut, and then that the viewer will concentrate on what is being said as a distraction from the breaking of cinematic convention.^{[ commendation needed ]}

Some styles used with the 180-degree dominion tin arm-twist an emotion or create a visual rhythm. By moving the photographic camera closer to the centrality for a close-up shot, it can amp up the intensity of a scene when paired with a long shot.^[eight] When the photographic camera is moved further away from the axis for a long shot after a shut-up shot, it may provide a break in the activity of the scene.^[9]

In the Japanese anime feature Paprika, two of the main characters discuss, and demonstrate, the disorientating effect of crossing the line.^[10]

Empirical research [edit]

Empirical evidence exploring the importance of maintaining the 180-caste rule is limited.^[xi] The bones premise is that abiding by the rule helps keep characters on the correct side of the screen.^[12] Thus, it is causeless that if the dominion is violated, information technology can lead to distraction,^[13] and disrupt the period of the moment.^[14] This is and then extrapolated to affect the rhythm, or emotions of the scene. However, these notions are rooted in filmmakers' subjective reports, rather than empirical prove.^[15]

There has been research that demonstrated crossing the line can negatively affect the accuracy of spatial representation of the scene.^{[16] [17]} Furthermore, flipping the characters' positions can disrupt the audience'due south agreement of the relative orientations on screen.^[18] Violations announced to also affect spatial retention for the location of objects in a scene, only does not bear on memory for the narrative, the order of unfolding events,^[19] nor the agreement of narrative period.^[20]

Broadly speaking, empirical research indicates that abiding by the 180-degree rule is not important in a applied sense. Accurate spatial representations are not of import for the scene, nor is it remembered across the longer duration of a pic.^{[21] [22]} Furthermore, more recent research demonstrated that while viewers tin can spot violations, the presence of these violations take no consequence on the enjoyment of the scene nor movie, when compared to not having violations.^[23]
