How to make a small B-level exam structure for photography?

The most important thing for screen design in photography composition is the balanced beauty of composition. In daily life, everyone may have the following experience: the chair tilt gives people an unstable feeling, and they are worried that they will fall down when they sit down. Most solemn and dignified things are very symmetrical, such as the stone lion at the entrance of the ancient palace, which gives people dignity and majesty. It exists in pairs, giving people a symmetrical aesthetic feeling. Therefore, the picture balance of photographic works is very important in composition. 1. Symmetry and balance are used in the picture, which symbolizes a high degree of neatness. For example, butterflies have always been admired for their symmetrical beauty in shape and wing patterns. Symmetrical pictures are often seen in photographic works, especially in stage photography. However, most photographic works do not pursue semi-symmetry in composition, but deliberately aim at the visual balance of the picture. Because in photographic composition, absolute symmetry will give people a static, stiff and monotonous feeling, and people's aesthetic requirement in life is still the pursuit of balance. Too much symmetry will make people feel dull and lack vitality. And balance is to break the rigid situation, which is both "equal" and flexible. The scope of balance includes the contrast of images in composition, the contrast between people, people and things, big and small, dynamic and static, bright and dark, high and low, virtual and real. Structural balance means that the scenery of each part of the picture should echo and contrast to achieve balance and stability. The balance of picture structure includes not only the size and weight, but also the balance of light and shade, lines, space and color. 2. the primary and secondary relationship in composition When taking photos of life, people are the main ones. Therefore, we should pay attention to the relationship between subject and companion, the relationship between main characters and secondary characters, and the relationship between characters and background when designing pictures. If a photo has only the main body and no foil, the picture will look dull and unchanged, but the foil can't usurp the role of the owner; The main body must be prominent on the screen, and it is necessary to abandon the complexity and simplify it. If necessary, you can change the shooting position and angle, or move unnecessary things to achieve the purpose of concise picture and prominent subject. It's a pity that some people's photos are overwhelmed by the messy background, and the protagonist is pushed aside. We can grasp the following two points in the relationship between primary and secondary images: ① If we encounter a messy background, we can take the method of enlarging the aperture to blur the background behind to highlight the main body. ② Choosing the right angle to shoot and avoiding the messy background can make the characters stand out. 3. The application of "golden section" in composition The so-called "golden section", that is, the "golden ratio" A:B=B:A+B, is often expressed in the ratio of 5:8 when applied to art and photographic composition, which is accurate enough in practical use, especially in photographic composition. In specific photographic composition, it can be applied to plot contrast, virtual contrast, dynamic contrast, size contrast and so on. The role of the golden section ① The sense of stability in dealing with the picture stability in photographic works generally refers to whether the horizontal and vertical lines of the scene are correct. (2) The blank space of the processing screen refers to the space on the screen. Generally, when shooting a moving object, we must pay attention to leaving a certain blank in front of the moving direction, which will help to strengthen the sense of space in motion. When shooting people, there should be a certain space in front of people's line of sight, so as not to leave a sense of hindrance. (3) Adjusting the position of the visual focus The most attractive part of the photo is the visual center. If we want to highlight the subject image, we should arrange it in the visual center.
