The RULE OF THIRDS is a commonly used guideline for helping with composition in photography and videography. The basic principle is to divide your image into thirds horizontally and vertically. These lines and their intersections act as guidelines for where to position important compositional elements in your frame.
It is particularly helpful for positioning your subject correctly for an off camera interview. Position the centre of your subject's body on the left third if they are looking across the frame from left to right. Position their eyes on the top third. As you can see below, the lines draw your attention to the subject's eyes which helps us to make a connection with the person as they speak.
