Screen Direction

During the editing and filming process, it's important to know the direction of the characters. For example, if a character is entering from screen left, in the next shot they need to be entering from screen left again. If this necessary rule is broken and a character enters from screen right, the audience will believe that the character has turned around. When moving in a diagonal motion, the same rule applies. As the character moves from long shot screen right to close up screen left, the next shot should show the character walking from screen right to screen left. If these rules are not followed, the audience will feel disoriented and believe that the character turned around while walking.
