Rule of Thirds: The Rule of Thirds is probably considered one of the most foundational principles in photography and film for creating dynamic and visually interesting images. Which of the following images best uses the Rule of Thirds?
C is the correct answer. According to this ever-popular and widely used principle, pictures and video become much more aesthetically appealing to the human eye when they are arranged in thirds. If you were to divide a picture up into thirds both horizontally and vertically, you would get 9 equal-sized rectangles and four intersections. Pictures that follow the principle best have the focal points right on (or really close to) one of the four intersections. The principle also suggests that a horizon line, if there is one, should land precisely on the lower or upper third line. In image C, the blue material on the boat and the setting sun both land on an intersection and the ocean horizon is right on the lower third line.
