The 180 degree line is a filming guideline that states that two characters in a scene should maintain the same left/right relationship to one another . When the camera passes over the invisible axis connecting the two subjects, it is called crossing the line and the shot becomes what is called a reverse angle. in the clips below we give a good example of the rule and also a bad example, and you can tell the difference between the two. Continuity editing can be divided into two categories: temporal continuity and spatial continuity. Within each category, specific techniques will work against a sense of continuity. In other words, techniques can cause a passage to be continuous, giving the viewer a concrete physical narration to follow, or discontinuous, causing viewer disorientation, pondering, or even subliminal interpretation or reaction, as in the montage style.
