The Rule of Thirds
The
rule of thirds is a concept in video and film production in which the
frame is divided into into nine imaginary sections, as illustrated above. This creates reference points which act as guides for framing the image.
Points
(or lines) of interest should occur at 1/3 or 2/3 of the way up (or across) the
frame, rather than in the centre. Like many rules of framing, this is not
always necessary (or desirable) but it is one of those rules you should
understand well before you break it.
In
most "people shots", the main line of interest is the line going
through the eyes. In this shot, the eyes are placed approximately 1/3 of the
way down the frame.
Depending
on the type of shot, it's not always possible to place the eyes like this.
In
this shot, the building takes up approximately 1/3 of the frame and the sky
takes up the rest. This could be a weather shot, in which the subject is actually
the sky.
