The Basic rule to filming with examples of Match on Action , Cutaway, Shot Reverse Shot and the 180 Degree Rule

1. The 180 Degree rule
shown(left)means that the camera
cannot cross this line as then the
people will be on the left and right
but if you cross this line then that
will show the opposite person on the
other persons side.

2. This is were two cameras are
playing at the same time and both
over the shoulder of different
people to show there p.o.v to the
opposite person.

3. Match on action is where the cameras
are filming but also somewhere else to
show the continuity for example
walking through a door one camera
outside showing someone walking in
while camera inside continues the
scene inside which presents it as
continuous..

4. A cut away is the interruption of a
continuity shot by inserting a view of
something else- This is normally used
to extend a scene but also to tell the
audience something for example the
ringing of a clock might portray
someone is late.
