Segmentation of portrait photography frames

Lead: Photography and painting have a lot in common, both are graphic arts, and both should focus on composition. However, photographic composition is very different from painting composition. Painting composition is based on subjective design, and photography is based on objective choice. Let's take a look at how photographic composition can be improved from painting composition.

Image segmentation

Photographic composition often needs to divide the picture into two or more planes, and the divided picture changes uniformly, which not only has the beauty of the dividing line itself, but also has the beauty of new patterns produced by the divided picture. The segmentation of the picture is directly related to the arrangement of space and subject. After segmentation, the original picture integrity has been destroyed, which requires the new picture to have both contrast and balance.

I. Production line

The existence of dividing lines can be seen everywhere in the world, the straight line formed by the horizon and the horizontal line, the curve formed by the river of the sun and the moon, and the lines of nature are so beautiful and attractive; A pen, a wall, a wire, a building, clothing, furniture, transportation and other human masterpieces also show beautiful lines; Among all things in the world, the lines of the human body are extremely beautiful, which excites many photographers.

1, straight line

The straight line is simple, straight, lively and decisive, giving people a strong and rational feeling. There are three kinds of straight lines in photographic images, namely horizontal line, vertical line and diagonal line. The horizontal line stretches gently, and the channel produces a greater sense of balance; Vertical lines make people feel rising, straight and powerful; Slant lines are unstable, changeable and dynamic, which are common in diagonal composition.

2. Curve

The curve is soft, round, smooth and changeable, which makes it soft and elegant. The rolling mountains and winding rivers will make people's eyes turn and think constantly. Various changes from the simplest arc to the free curve constitute a colorful curve world. The combination of curves and straight lines can divide an infinite surface. The change and arrangement of lines in photographic images will produce different visual effects and psychological induction. The length and thickness of lines also have different symbolic meanings.

Second, the golden section.

There are straight line segmentation and curve segmentation, equal segmentation and equal segmentation, and the most important thing is? Golden section? .

Ancient Greek architects have long realized that satisfactory visual effects can be achieved by using a mathematical calculation method for layout and composition, which is the golden section method. The golden section is also called. Golden ratio? Or? Gold interest rate? . Divide a line into two sections, and the ratio of the length of the whole line to the longer part is equal to the ratio of the longer part to the shorter part, that is, 1: 1. 18. This proportion has universal aesthetic value in plastic arts.

The rectangle formed according to the ratio of 1: 1.6 18 belongs to the typical golden ratio, such as the picture taken by 135 camera, and the negative is 24mmX36mm, which is the ratio. So most rectangles have good visual effects. If a rectangle is divided into nine equal parts, there will be four dividing lines in the picture, right? Gold thread? Is this dividing line also called in China? Jiugongge? . Four? Gold thread? What is intersection? Golden section? These four points are the visual center of the picture. Because people see with two eyes, physiological reasons determine that people's visual center is not in the center of the picture, but on both sides of the center. What's the best location? Golden section? . Photographic composition follows this ancient law, and the structural center of the picture is often placed somewhere. Golden section? Let's go

? Golden section? Any point is a good place to arrange the main body. Arranging the subject at the golden section can form an angle, which is convenient for looking around and echoes with all parts of the picture. Even standard images? Golden section? The eyes of a standard portrait are generally located at two golden points in the picture, otherwise it will make people feel uncomfortable. Of course, the golden section method is a traditional composition method, which cannot be fixed and should be used flexibly.

Third, the distribution of space.

The space allocation of photographic pictures should be determined according to the characteristics of the subject and the accompanying body, and the sense of form of picture segmentation should also be taken into account.

1, directionality of the subject

If the subject is sideways or semi-sideways, there should be a large space in front of the person, otherwise it will make people feel embarrassed. People who walk or run should also have a large space in front of them, otherwise people will feel that the shutter is too late. You should also leave an open space in front of the door when shooting buildings, and so on.

2. Main arrangements

Themes can be arranged on either side of the screen according to the needs of the content. But in general, the subject is too high, which makes it look heavy and light; The main body is too low, it seems that the lower part is heavy and the upper part is light; Too far to the left or too far to the right will cause the phenomenon that one side is heavy and the other side is light. Therefore, the arrangement of the main body should consider the balance of the picture.

When shooting a character, it seems a little that the hair of the character reaches the top border. Top？ ; When the character's foot steps on the next frame, it appears again? Is it tight? A little bit. Under normal circumstances, leave room around the characters, and don't let them appear stiff and stiff. It's called. Leave the picture blank for three minutes, and you will get angry. ?

3. Horizon and horizontal line

The horizon and horizontal line are usually arranged in the middle of the picture, otherwise it looks like dividing the picture in half. If the sky is rich in layers and there are many attractive contents, you can raise the lens, lower the horizon or horizontal line and put it on the lower one? Gold thread? On, so the sky accounts for 2/3 of the picture; If there is nothing in the sky and there are many things worth showing on the ground or on the water, then put the horizon or horizontal line on it? Gold thread? Let the ground occupy two-thirds of the picture.

When taking ordinary pictures of people, keep the camera on, and don't let the horizon or horizontal line tilt, otherwise it will destroy the stable aesthetic feeling of the picture.
