Rules Of Thirds

Rules of third 

According to the rule of thirds, the subject of an image should be on the left or right third of the frame, leaving the other two thirds more open. Two similarly spaced horizontal and vertical lines break the image into nine equal sections. Typically, the rule of thirds results in photos that are interesting and well-composed.

Your grid's intersection points for the rule of thirds are the corners of the central square. The focal point of your photograph should be placed here, similar to four crosshairs focusing on the shot's key components. It aids in creating a balanced composition in your shot that will catch the viewer's attention by balancing your main topic with the empty space.
