180 degree rule P1

180 degree rule is the rule were if filming or using  a camera you stay on one side of an invisible line, if this rule is broken and you cross over the line, it could create confusing for the audience watching the video as it looks like the people in the shot has switch sides and does not look right.

If you look on the diagram and look at the bottom right picture of the over the shoulder shot of the blue person, the blue person is on the right and then if you look at the top right picture, because the camera has broken the rule and gone over the 180 degree line it looks like the two characters has switched sides and this will most of the time cause confusing with the audience. In some films they do break the rule but make it work well as it is hard to pull of.
