The 180 Degree Rule!

In film or television there is always are rule which, when broken, is known as "Crossing The Line". The line represents half of 360 degrees (a full circle), so half that is 180 degrees. This method is to help the audience know where characters are in a scene when they are being filmed.

Using this rule, we got into groups of four and we filmed a scene using this rule and we all each took a turn using 2 actors, one on camera and directing, and one on sound. This was my piece although I wish the sound was higher, the shots I took were fluent and looked focused and angled quite nicely.
This video explains the 180 Degree Rules while still using the method as it is filmed.
