Rules of filming

Rule of thirds:
The rule of thirds is applied by aligning a subject with the guide lines and their intersection points, placing the horizon on the top or bottom line, or allowing linear features in the image to flow from section to section.




Shot reverse shot:
Shot reverse shot is a film technique where one character is shown looking at another character, and then the other character is shown looking back at the first character


180 degree rule:
the 180-degree rule is a basic guideline regarding the on-screen spatial relationship between a character and another character or object within a scene. An imaginary line called the axis connects the characters, and by keeping the camera on one side of this axis for every shot in the scene, the first character is always frame right of the second character, who is then always frame left of the first. The camera passing over the axis is called jumping the line or crossing the line.




Match on action:
A match on action shot, is a cut that connects two different views of the same action at the same moment in the movement. By carefully matching the movement across the two shots, filmmakers make it seem that the motion continues uninterrupted. For a real match on action, the action should begin in the first shot and end in the second shot.




30 degree rule:
The 30 degree rule states that a shift in camera angle between successive shots of the same subject should exceed 30 degrees.
