The document discusses the 180-degree rule demonstrated in a video called "The Stairs". In two different shots from different angles, one character stays on the right side and the other stays on the left, following the 180-degree rule. This allows the audience to see the mood and reactions from both characters' points of view and see the unseen movement around the characters.

1. 180-degree rule example
These two screenshots, from Jack and Dean’s video ‘The Stairs’ demonstrates the 180⁰ rule ( two
characters within a scene should have the same left-right relationship) as in both shots, even though
they’re from two different angles, Dean stays on the right hand side in both shots and Jack stays on the
left hand side of the shots. The effect this has is that you see from both boys point of view which shows
mood and reactions of both characters. The 180⁰ rule allows the audience to see the unseen movement
happening around and behind the focused character.
