Composition, the rules of.

I learnt that composition is basically the frame in which the scene is shot, which makes it visually interesting to the audience. It's basic guidelines for filming and there are sub- ideas to it such as...

The Rule of Thirds - This is where you imagine a grid of nine squares covering the shot. Sometimes, the grid is already over the camera so it can help when filming. The object of interest in the piece should be situated where the lines overlap. Below, I've drawn a picture to remind myself of this rule, when needed.

There are other factors of composition such as...

Head Room - this is where you need to have a good enough distance between the top of the person's head and the top of the frame. 

Look Room - It's sometimes called Nose Room and it basically is the distance between the side edge of the frame and the person's nose. 

Lead Room - This is when the camera follows (pans) the moving object in the scene. 

There are other shots that are used in composition like eye level shots, low and high angle shots etc.

An important factor of composition is simplicity - meaning not too much happening in the background so the audience can focus their attention on the main object and balance - meaning if there is an object on the left hand side of the frame, something needs to be placed on the right to balance out the shot, and vice versa.
