How to treat the most perfect statement of the golden ratio?

The golden section can be said to have a natural connection with the composition of photographic pictures. For example, the film window ratio of a camera is 135, and the camera is 24X36, which is a ratio of 2:3, which is very typical. The 4.5X6 of 120 camera is about 3: 5. Although 6x6 is a box, the post-production is still mostly cut into rectangles, which is similar to the golden ratio. As long as we open the album and have a look, we will find that most of the painting forms are similar to this ratio. This may be influenced by tradition and form people's aesthetic habits.
