axis of action

In the continuity editing system, the imaginary line that passes from side to side through a main actors, defining the spatial relations of all the elements of the scene as being to the right or the left. It is also called the 180-degree line. When the camera crosses this axis at a cut, those spatial relations are reversed thereby confusing the audience. It is one of cardinal rules of continuity editing not to cross this axis during a sequence.
