The recommended composition rules commonly used in photography are as follows: 1. Tic-tac toe composition. Distribute two horizontal lines and two vertical lines evenly in the picture. Divide the picture into nine parts horizontally and vertically to form a tic-tac-toe shape. Arrange the main body in the picture.

At the intersection of the tic-tac-toe shape, it is the tic-tac-toe composition.

Because the picture is divided into nine parts, the tic-tac-toe composition is also called the nine-square grid composition.

2. Rule of thirds composition: Divide the subject into three horizontally or vertically, which is called the rule of thirds composition.

Using the rule of thirds to compose a picture, you can divide the picture into three equal parts, and you can also flexibly divide the proportion of each part according to the situation of the picture.

3. Leading line composition. Street lamps, bridges, streets and other things in our lives that can stretch into the distance to form a line can be used as materials for leading line composition. Using leading line composition can well guide the audience's sight into the distance, making the

The eye can have a focus on the picture.

4. Converging line composition. Some lines in the picture extend in the same direction and converge into a point at the end of the line. Composing such a picture is called converging line composition.

Usually, two or more such lines in the picture can produce a convergence effect, thereby guiding the audience's line of sight from near to far, giving the audience a strong sense of space and depth.

5. Symmetrical composition: When the subject has a symmetrical relationship, we can use symmetrical composition to express the picture. This form of composition is more rigorous and pursues the unity and harmony of the scenery on both sides of the picture.

In mathematical geometry, symmetrical graphics themselves give people a sense of stability and balance. When we apply this balance to photography, the photos we take will give people a sense of harmony, balance, and uprightness.
