Shot reverse shot is a film editing technique that alternates between two characters in a scene to imply they are looking at each other. It switches between close up shots of each character as if looking at the other. The 180 degree rule establishes an imaginary line between two subjects in a scene, requiring the camera to always be on the same side of this line to maintain spatial relationships. Match on action cuts between shots so the action is continuous, such as cutting to a door opening as a hand touches the doorknob. Eye line match ensures a character's gaze lines up with the person or object they appear to be looking at in the following shot.

1. Shot Reverse Shot
• Shot reverse shot is used to show two characters in a scene
from two perspectives but not from a direct observation of
the other person. It makes the audience assume that the two
characters which are usually sitting or standing opposite each
other in a scene are looking at each other.
• It is shown through the editing of the scene where one
character is portrayed looking at another character and then
the other character is shown looking back at the first
character. This is usually displayed to the audience as an 'over
the shoulder shot'.

3. 180 Degree Rule
• In film making, the 180-degree rule is a basic guideline
regarding the on-screen spatial relationship between a
character and another character or object within a scene.
• An imaginary line called the axis connects the characters, and
by keeping the camera on one side of this axis for every shot
in the scene, the first character is always frame right of the
second character, who is then always frame left of the first.
The camera passing 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 round.
• The object that is being filmed must always remain in the
centre, while the camera must always face towards the
object.

5. Match on Action
• Match on action refers to film editing and video
editing techniques where the editor cuts from one shot to
another view that matches the first shot's action.
• A common example is a man walking up to a door and
reaching for the knob. Just as his hand touches the knob the
scene cuts to a shot of the door opening from the other side.
• Although the two shots may have actually been shot hours
apart from each other, cutting on action gives the impression
of continuous time when watching the edited film.

7. Eye line Match
• Eye line match means that the gaze of the
character in one shot has to line up with the
person or thing they’re looking at in the next
shot
• To get this right, you should put both camera
positions at a similar distance from the ‘axis’.
