These three techniques include:
Match on action
Shot/Reverse shot
180 degree rule
My short film will involve a character opening a door and walking across the room to sit down opposite another character, where the they will exchange a few lines of dialogue.
Match on action
Shot/Reverse shot
180 degree rule
This where the camera either pans or cuts to different views without breaking the 180 degree rule, which means the camera either stops panning or the cutting stops soon as it reaches the 180 degree angle. In this shot the subject or subjects are in the same position throughout.
