180 Degree Rule

One aspect of our preliminary task that we had to focus on was the 180 degree rule.

It is a basic guideline when making a film that says that two characters in the same scene should always have the same left/right relationship to each other. The camera however can cross over the imaginary line connecting the characters, which is known as crossing the line. The new shot would be a reverse angle.

Here is a link to a video that cleary shows the 180 degree rule within a scene.
