The 180 Degree Rule

The 180 degree rule is a basic guideline in film making that states that two characters (or other elements) in the same scene should always have the same left/right relationship to each other. If the camera passes over the imaginary axis connecting the two subjects, it is called crossing the line.  The new shot is called the reverse angle.

When I filmed my Preliminary Exercise I included the 180 degree rule. I included a wide range of camera shots and movements which showed the relationship between two characters.
