What is the golden ratio of photography?

The golden ratio is 1: 0.6 18. Its essence belongs to a mathematical calculation method, and its founder is Pythagoras, a famous mathematician in ancient Greece. Modern people think that the golden ratio is a good ratio because many proportions in the human body structure are close to 0.6 18. Da Vinci, a famous painter and anatomist, found through autopsy measurement and research that many proportions in human body structure are close to 0.6 18. The human body itself is an outstanding sample of the golden ratio.

Brief introduction of golden ratio

The golden section refers to dividing the whole into two parts, and the ratio of the larger part to the whole is equal to the ratio of the smaller part to the larger part, and the ratio is about 0.6 18. This ratio is recognized as the most aesthetic ratio, so it is called the golden section.

In ancient Greece, Pythagoras was walking in the street one day. Before passing the blacksmith's shop, he heard the sound of striking the iron, so he stopped to listen. He found that the blacksmith had a regular rhythm in striking iron, and the proportion of this sound was expressed mathematically by Pythagoras.

Mathematical definition of golden ratio

When a line segment is divided into two parts so that the ratio of the larger part to the total length is equal to the ratio of the smaller part to the larger part, this ratio is the golden section. The ratio is (√ 5- 1): 2, and the approximate value is 0.6 18, which is usually expressed by the Greek letter Ф.
