The 180 degree rule is the rule in which you
keep the camera placed on an imaginary axis around two characters you are
filming, not breaking the 180 degree barrier around one side of the two
characters, keeping the left character on the left and the right character on
the right. When filming a sequence, you must keep to that one side you choose
in order to keep continuity in both of the characters eye lines,looking
towards one another.
This picture I
copied from Flickr demonstrates this rule, the camera keeping in the blue semi
circle. The red character stays on the left, and the blue character stay on the
right, as if both characters are looking at one another. If the camera then
breaks this semi circle, as pictured above, the blue character now appears on
the left, and the red character now appears on the right.
Shot reverse shot
is the transition of edited shots between two characters having a conversation
or engaging in another kind of dialogue. The shots follow the conversation
between the characters, keeping to continuity of the eye lines of them both
looking to one another.
The diagram above, which I copied from Google images, demonstrates the shot reverse shot rule, straight cutting between two characters as they engage in dialogue.
