Photographic composition refers to the arrangement and arrangement of elements in the picture in order to achieve artistic beauty and expressiveness. Good composition can make photos more attractive, layered and visually impactful. Here are some common photographic composition techniques:

1. The third division method:

Divide the picture into nine equal grids, and place the main elements near the intersection or along the grid lines to enhance the balance and attraction of the picture.

2. The main body is prominent:

By letting the subject occupy most of the screen space and using a bright and contrasting background, the subject is more prominent.

3. Enhanced prospects:

Introducing foreground elements into the picture can increase the depth and layering of the picture and make it easier for the audience to enter the picture.

4. Blurred background:

By choosing appropriate aperture, focal length and shooting distance, the subject is clear and the background is blurred, thus highlighting the subject and creating artistic effects.

5. Diagonal composition:

Use diagonal lines to guide the viewer's line of sight and enhance the movement and tension of the picture.

6. Contrast and contrast:

Through the contrast of color, light and shade, texture and other elements, highlight the important elements in the picture and increase the visual impact.

7. Repetition and pattern:

Look for recurring elements or regular patterns in pictures to create a sense of harmony and balance.

8. The golden section:

Divide the picture into golden proportion parts, and put the main elements on the golden line or golden point to create a more attractive composition.

These are just some common photographic composition techniques. According to the different scenes and shooting themes, you can also combine other techniques and ideas for composition. The most important thing is to keep practicing and observing, and cultivate your own photographic vision and composition ability.

Good composition can help photographers create balanced, beautiful and layered photos, guide people's eyes and attention, and convey the theme and emotion that photography wants to express.
