Continuity

So  What is continuity?

In fiction, continuity  or  time-scheme is consistency of the characteristics of persons, plot, objects, places and events seen by the  viewer  in a certain scene . It is of relevance to several media audiences
Continuity is particularly a concern in the production of film and television due to the difficulty of  correcting an error in continuity after shooting.
For example in Terminator 3: Rise Of The Machines the number on the tail of the plane clearly changes threwout the flim.
Its Highly important to keep continuity in a flim because it can confuse the viewer further more it can aslo pull the viewer out of the atmosphere and break suspenison.This would mean the viewer would become dettached from the flim and lose intrest  quickly.





The 180° Rule:
In film making, the 180° rule is a basic guideline that states that two characters  in the same scene should always have the same left/right relationship to each other. If the camera passes over the imaginary axis connecting the two subjects, it is called crossing the line. The new shot, from the opposite side, is known as a reverse angle.
