180 degree Rule

The 180 degree rule:
It's useful because it's establishing the scene and where the people are and the setting, and maintaining the background space and continuity.
It ensures the audience are aware that the characters are in the correct placement
The rule is you cant cross the line unless you show the camera movement. movement not shown clearly could cause, wrong eyeline, characters facing the same way, disorientation (different setting).
