Golden ratioIn photography, the golden ratio was an important concept of composition. In terms of mathematical definition, a line segment was divided into two parts. The ratio of the longer line segment to the full length was equal to the ratio of the short line segment to the long line segment. The ratio was 0.618. This point was called the Golden Section Point. Although it was not as accurate in photography composition, there were many applications related to the golden ratio.
A common application was the golden ratio, such as 2:3, 3:5, 5:8 and other approximate proportions were often used in photographic composition, also known as the golden ratio. There was also the Nine Palace Diagram, which drew two horizontal and vertical lines (virtual) on the screen, dividing the screen into nine equal squares. The four points where the horizontal and vertical lines intersected were the golden ratio points. In theory, they were close to 1/3 and 2/3 (0.666) points. The theme could be placed near these golden ratio points.
From the perspective of image division, taking a photo with a ratio of 3:2 as an example, a diagonal line could be drawn, and then a vertical line could be drawn from one of the other two corners to the diagonal line to divide the picture into three parts. When the area ratio of the two parts was approximately 0.618:1, if the main scenery was divided according to this ratio, the photo would have a sense of beauty.
In addition, the golden composition point was also based on the application of the golden ratio. After the golden ratio was applied to the photo, the vertical line from a corner to the diagonal was the golden composition point. When the main scenery was placed on the composition point, it could make the main body stand out. There were usually four such golden composition points in a picture, and it had to be applied flexibly according to the actual situation.
If the main body of the photo was not obvious or scattered, there was another simplified form. That was to draw a line from the golden composition point and let the main body be distributed on this line. This was the case for the three-point composition. The picture could be roughly divided into three parts, one part for the sky, two parts for the water, and the main body was in the middle of the water. In actual shooting, there was no need to strictly divide the picture into three parts. One area would take up 1/3 of the picture, and the other area would take up 2/3. The upper and lower positions of the three-point line could be flexibly adjusted according to the subject.

Golden ratioUsing the golden ratio in shooting was an important principle of composition.
From a mathematical point of view, the golden ratio was to divide a line into two segments of different lengths. The longer segment accounted for 0.618 of the total length. This ratio was considered the most aesthetic ratio. When framing and composing, the main elements of the picture were laid out according to the golden ratio, which could achieve a harmonious, balanced and rhythmic visual effect.
For example, when shooting a character, you could place the key parts of the character (such as the eyes) on the golden ratio of the picture; when shooting a landscape, you could place the prominent scenery (such as mountains, buildings, etc.) in the position of the golden ratio of the picture. Like many classic paintings, the composition was also based on the golden ratio. For example, the Mona Lisa's facial contours and shoulder lines, as well as the edges of the background wall, all showed the golden ratio. The golden ratio principle was also widely used in photography, film, and other visual arts to help creators construct more beautiful and attractive images.

photography and the golden ratioIn photography, the golden ratio was very important. From a mathematical definition, a line segment was divided into two parts. The ratio of the longer line segment to the full length was equal to the ratio of the shorter line segment to the longer line segment. When the ratio was 0.618, this point was the golden section point. Although photography did not require such precision, it followed a similar principle.
On the one hand, there were similar golden ratio relationships in photographic composition, such as 2:3, 3:5, 5:8, etc. These proportions were often used in photographic composition. In terms of operation, one could draw two horizontal and vertical lines on the screen to divide it into nine squares (a nine-square diagram). The four points where the horizontal and vertical lines intersected were the golden ratio points. In theory, it was close to 1/3 and 2/3 (0.666). The theme could be placed near these points. When taking a portrait, one had to determine which point to place it according to the face. This way, it could better play the role of the main scene organization, coordinate the surrounding scenery, produce beauty, and highlight the main scene. Moreover, considering that people tended to view pictures from left to right, it would be better to place the main scene or eye-catching image on the right.
On the other hand, according to the Golden Section Method, it was simply to use two horizontal lines and two vertical lines to divide the photo into three equal parts (strictly speaking, it should be 0.618 points). The intersection of these lines was the Golden Section Point. When people or objects were arranged here, the picture would be more harmonious and charming. For example, when shooting a character, the eyes of the subject could be arranged on the "tic-a-square" focal point or line, leaving more space for the character to face the direction. At the same time, using the golden ratio method, one could also directly obtain a triangle composition method. The bottom edge was parallel to the photo, and the height was one side of the "well", which could form a stable composition.
In short, the Golden Section Method was a common basic method in photography. Beginners could use this method to practice composition and improve the aesthetic value of their work. However, photographers should not be limited to this method. They also needed to consider the shooting space, the echo of the main body and the background, the expression of the main idea, the tone, the light treatment, the color performance, and many other factors. At the same time, they should constantly learn aesthetic knowledge, strengthen their aesthetic cultivation, look at other people's works, and practice and summarize them to take photos of a higher artistic level.

How to get the golden ratio line for the iPhone camera?He opened the camera option in the phone's settings and set the grid line to a 3×3 nine-square grid composition interface. The four points where the horizontal line and the straight line of the nine-square grid intersected were the " well " points, which were also the golden section points. These points were usually the focal points of our human eyes. When shooting, the subject could be placed at these points.

How to use the golden ratio of the reference line in the cameraThe method to use the golden ratio of the reference line in the camera is as follows:
- ** Confirm the golden ratio point **:
- For the Huawei phone, open the camera, find the settings, and select the reference line as the golden ratio in the settings; for the Apple phone, open the settings, find the "grid" in the camera options in the settings, and open it; for the Oppo phone, click on the three horizontal lines in the upper right corner to open the settings, and then open the grid. After opening it, four lines and four intersecting nodes would appear on the phone camera. These four nodes were the approximate golden ratio points.
- According to the Nine Palace Diagram, the picture was divided into nine equal parts to form the word "Jing". The four intersections in the middle were the golden section points, which were the visual center.
- ** Arrange the subject's position according to the subject's size and shooting requirements **:
- If the main body was small, it could be placed on one of the four nodes on the screen. However, the specific placement also needed to take into account the environment, such as the background, the accompanying body, and other factors.
- If it was a portrait, the conventional method was to place the person on the 1/3 line. When shooting a long distance, the person could be placed in any grid of the nine squares, and the other eight squares would be used as the background. This way, the composition would be more artistic. The golden ratio could be used to highlight the subject when taking various portraits (such as close-up-big-head photos, close-up-half-body photos, mid-shot-half-body photos, panoramic-full-body photos, and long-range-full-body photos).
- When shooting, the subject was arranged at the golden ratio point or near it, which was conducive to coordinating the relationship between the main body and the secondary body. It could attract people's visual senses and make the picture more beautiful.

The golden ratio between the size of the dining room and the size of the dining tableThe golden ratio of the restaurant's area to the size of the dining table was 6:1. For a table for six people, it is recommended to choose a rectangular shape with a length between 1200mm and 1500mm, a width between 800mm and 900mm, and a height of 750mm. For a table for four people, it is recommended to choose a square with a size of 800mm x 600mm or 600mm x 600mm, and a height of 750mm. In addition, the dining table could be made of wood, glass, or rattan chairs. The golden ratio between the size of the dining room and the size of the dining table was to allow the dining table and chairs to be placed completely and leave enough space for people to walk around.
