What is the rule of thirds? The rule of thirds is a composition guideline that places your subject in the left or right third of an image, leaving the other two thirds more open. While there are other forms of composition, the rule of thirds generally leads to compelling and well-composed shots.
There is a great article by Dutch photographer Nando Harmsen on fstoppers that goes into great detail on this subject.
The rule of thirds is the first thing that is taught about composition in photography. It seems to have some similarities with the golden ratio, but in reality, it’s something completely different. Let’s have a closer look at the history of these so-called rules to get a better understanding.
The rule of thirds is quite a simple rule. Divide the image in nine equal parts, by drawing two horizontal and two vertical lines at thirds from the edges. Place your subject on one of the lines or at the intersection of the lines, and you’re done. Sort of.
Although this can help to achieve an acceptable composition in some situations, the rule of thirds was never intended that way. In fact, the origin has absolutely nothing to do with drawing lines at thirds of the image. At first look, the similarity with the golden ratio does make it seem the two are related. Nothing is further from the truth. Let me explain why by diving into history.
