180 Degree Rule

From this video which I have found on You Tube as well as other sources from class, such as text books I have learnt that the 180 degree rule is the key to keeping a conversation going in between two people without confusing the arrangements of location of them. The best way of remembering this is to imagine a bird's eye view over looking the whole room and then draw an imaginary line in the centre of the two people. If you're using more than one camera, the key is not to cross the 180 degree imaginary line so that the audience doesn't loose track of where the two people are located during the conversation.
