1. Origins of the rule of thirds
The rule of thirds is a compositional guideline. Its origins go back to classical and Renaissance paintings, but it is mostly known as a compositional tool used by photographers. This painting by Valentin de Boulogne shows how the main characters are all placed on the upper dividing line, creating a dynamic arrangement of figures.
2. The rule of thirds in landscapes
The rule of thirds is mostly known as a tool for composing landscapes. In this painting by Pierre Henri de Valenciennes, the horizon is placed in the lower thirds, and the large mass of mountains and scenery is placed in the left section, to create a more dynamic scene.
3. The rule of thirds for asymmetric compositions
The main function of the rule of thirds is to help create asymmetric compositions. If the elements in a picture are centred and too balanced, it becomes boring. If the images are offset using the rule of thirds, the asymmetry and counterbalance of elements creates a much more dynamic picture.
4. Place focal points with the rule of thirds
Another great way to use rule of thirds is to help place focal points. In this portrait painting, the eyes fall on the upper horizontal line and leads to the second focal point in the ear. Other points of interest such as the warm triangle of light also fall on an intersection of guidelines.
5. Guide eyeflow with the rule of thirds
Eyeflow is another great use of the rule of thirds. In this painting by Rubens, the main focal point of the boar is placed at an intersection. Secondary points of interest fall on intersections as well and the action of the poses lead the eye from one focal point or intersection to another.
Challenge: Using the rule of thirds design and paint a painting. The more you practice the better you'll get.
