Rule Of Thirds
(My Definition) Rule Of Thirds - This is when you divide an image, using 2 horizontal and 2 vertical lines, therefore resulting in the creation of 9 sections.
When you are taking a photo, you are already doing this in your head, deciding which part of the frame is the main focus. However With This Grid, (rule of thirds) , it recognizes the four main points of the image, that you would focus on as you are framing the photograph.
