180-degree rule
The 180-degree rule is a filmmaking guideline that helps maintain spatial consistency in a scene. It establishes an imaginary line, known as the "axis," between two characters or elements. When filming, the camera should stay on one side of this line to ensure that the audience can easily follow the action and understand the relationship between the characters.
If the camera crosses the line, it can confuse viewers by reversing the positions of the characters. This can disrupt the flow of the scene and make it harder for the audience to comprehend the spatial dynamics. Following the 180-degree rule enhances storytelling clarity.
