A continuity technique that uses jump cut editing in order to give the viewer the impression of one continuous take. The clips that you edit together have to have the action at the same speed in each clip. e.g. Walking across a room, the actor has to be walking at the same speed in both of the clips. If the actor leaves the screen on the left they have to re-enter on the right. The action at the end of one clip has to be the same at the action at the start of the other clip.
Shot/ reverse shot is another one of the three principes of continuity. Shot/ reverse shot is where character A is shown in the shot to be looking at character B who is off the screen, and then the character B is shown looking back at character A. Since the characters are shown facing in opposite directions, the viewer assumes that they are looking at each other. Yet the charcters may be alone. This is a really good film techniques as you only need one camera, and the screen can be filmed with only one of the characters present.
The 180° rule is one of the key principles of continuity. The rule states that two characters/ objects which are in the same scene should always have the same relationship with each other, meaning left/ right to each other. I think that this picture is really good as it shows what the subjects will look like from either side of the imaginary line.
