The 180 degree rule states that the camera must stay on the same side of an imaginary line between two subjects having a conversation to avoid making it seem like they switched positions. Match on action involves editing two shots together so that the image, composition, or position matches exactly to ensure continuity of action. A shot reverse shot juxtaposes three shots - one of subject X, then subject Y, then subject X again to establish eye contact or conversation between the subjects.

1. The 180 Degree Rule
The 180 degree rule is a rule used in film making and is where the camera
must stay on the same side of a 180 degree axis line, or on the same side
of two subjects. For example:
Two subjects are having a conversation in a particular scene, the light bear is on the left hand
side, and the darker bear on the right...
The camera must not shoot beyond
the 180 degree axis line, otherwise...
....it will appear to the audience as though the characters
have switched positions, and may be confusing i.e. now
the lighter bear is on the right and dark bear on the left.

2. Match on Action
Match on action/match cutting is a technique
used in editing to give the piece a sense of
continuity. It is where two different shots are
edited together so that the image
seen, composition, or position matches up
exactly from the first shot to the next. This
ensures that the action of the film is
continuous and makes sense to the audience.

3. Shot Reverse Shot
This is a juxtaposition which is used to establish eye contact
or a conversation between two subjects. It includes three
shots edited together, one of subject X, the second of subject
Y, and then subject X again. For example, a shot reverse shot
may be edited like this...
Character X Character Y Character X

4. Extreme Close Up (ECU)

particular feature or
action

5. Close Up (CU)
Used to show

6. Bust Shot (BS)
Used when the

8. Long Shot (LS)
The full body.

9. Extra Long Shot (ELS)
Also known as an

how they are
moving, but also
where they are

10. Two Shot (TS)
These shots allow you to
see an important
interaction in a shot
between two subjects.

11. Over Shoulder Shot (OS)
OS shots focus on one
person as seen from
another subjects’
perspective or from
‘over the shoulder’. This
is often used in
conversation where the
camera focuses on the
person speaking, but
we can also see the
person listening.
