Rules of Filming

                                      

180 Degree Shot:

 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. This is mainly used in a dialogue scene between two characters. 

Shot Reverse Shot:

 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. Since the characters are shown facing in opposite directions, the viewer assumes that they are looking at each other.

Match on Action:

A film editing and video editing techniques where the editor cuts from one shot to another view that matches the first shot's action. A common example is a man walking up to a door and reaching for the knob. 

Continuity Editing: 

The predominant style of film editing and video editing in the post-production process of film making of narrative films and television programs. The purpose of continuity editing is to smooth over the inherent discontinuity of the editing process and to establish a logical coherence between shots.
