Rules of Filming

The 180 rule

This rule states that there is an imaginary line on the camera and therefore the camera has to stay on that side of the line. If the camera went past this line then it would make characters look like they are talking to themselves. This may cause confusing in the audience. It will also contain jump cuts.

The 30 degree rule

This rule states that following the 180 degree rule, the camera can not move less that 30 degrees because the video will be filled with jump cuts. However, moving the camera more than 30 degrees will also make the film contain jump cuts and will therefore look the film look fake. 

Shot reverse shot

This is typically used between the conversation of two characters. The camera will focus on one person when they are speaking and then change to focus on the next person when they answer. This links to the 180 degree rule because the characters will be on the line. If the camera was to move on the other side of the characters it will make them look like they are talking to themselves.

Match on Action

Match on action is used to cover a cuts. It helps to keep the film flowing and look more realistic. This will help draw the audience attention away from the slight cuttings and focus on the close up.

Rule of Thirds

This rule is 2 vertical and 2 horizontal lines which all connect with each other to make a grid. When there are people involved with the rule of thirds the camera will usually be positioned at least a third or two thirds down of the characters face.
