In the composition technology of digital cameras, the correct statement is

In the composition technology of digital cameras, the correct statement is: the shooting theme must be determined first; Put the theme on the point of the center of interest or the line of the center point; Grasp the distance, direction and angle of shooting;

Digital camera composition

1, triangular synthesis

In fact, it is only a simplified version of the golden section, and its basic purpose is to avoid symmetrical composition. Triangular composition can be divided into horizontal trisection and vertical trisection. It means dividing the picture into three equal parts, and each equal part can be placed in the center of the subject form, so it is appropriate to express the subject with multi-form parallel focusing. It can represent not only large spaces and small objects, but also small spaces and large objects. A little composition is one of the composition rules used by photographers in class, which is concise and can clearly express the theme.

For example, when shooting landscape works with the horizon, in order to avoid the rigidity of the whole picture caused by the horizon in the middle of the picture, the photographer should consider putting the horizon in one third of the picture. When shooting portraits, photographers should also avoid arranging characters in the middle of the picture, and should put them on the three-point line of the picture as much as possible, so that the visual sense will be stronger.

Jiugongge composition

Jiugongge composition, also called tic-tac-toe composition, is actually a form of dry golden section. Jiugongge composition is to divide the picture into force blocks evenly and arrange the main position at any of the four corners of the central block. In fact, these points are all in line with the "golden section law" and are the best positions in the picture. Jiugongge composition can make the picture change, dynamic and more dynamic.

Of course, these four points also have different visual senses. The upper two points are more energetic than the lower one, and the left one is stronger than the right one. But the point is to pay attention to visual balance.

2. A-shaped and triangular composition with strong sense of stability

A-shaped composition refers to arranging the structure of the picture in the form of a word in the picture. A-shaped composition has a strong sense of stability, and the site photographed in this form has a strong impact and strong visual guidance, which can be used to express the shape of tall natural objects and objects themselves. In the process of shooting, if the subject to be shown is placed at the junction of the top of A, it can play a mandatory visual guidance role.

triangular structure

Triangle is a balanced and stable morphological structure, and photographers can apply it to photographic composition. Triangle composition can be divided into regular triangle composition, inverted triangle composition, irregular triangle composition and multiple triangle composition. Regular triangle composition can create a sense of overall stability of the picture, giving people a powerful and unshakable impression;

The inverted triangle composition gives people a sense of tension caused by openness and instability; Irregular triangle composition can give people a sense of spirituality and jumping, while multiple triangle compositions can show lively movement, which is more common in shooting valleys, waterfalls, mountains and so on.

In the process of triangle composition, there is another situation in which the triangle situation in the picture is used to highlight the main body. This triangle composition is a way of visual perception, which consists of shapes and shadows. If it is a naturally formed linear structure, the main body can be arranged at the center of the hypotenuse of the triangle at this time, but the effect is best when there is only a panoramic view.

In addition, triangle composition can be used for photographing different scenes, that is, it can be used not only for remote guidance and heatstroke, but also for photographing people and close-ups.

3. Increase the presence of mouth components.

Mouth composition is also called frame composition. Generally, this composition is mostly used in the foreground, such as using doors, windows, mountain passes, frames, etc. As a prospect to express the rich and clear environment. This form of composition is more in line with people's visual experience, and the rich can look at it by asking or wondering, thus producing a stronger sense of realistic space and a certain perspective effect.

4. Full dynamic S-shaped composition

S-shaped composition is also called zigzag composition. When the main outline of the picture is basically S-shaped or zigzag, it constitutes an S-shaped composition. S-shaped composition has a strong dynamic effect, which is both dynamic and stable. It is not only suitable for expressing the natural ups and downs of mountains, rivers and regions, but also suitable for expressing the curves of human bodies or objects, especially the beautiful lines of women, which is more expressive.

5. V-shaped composition as foreground

V-shaped composition is the most varied composition method, mainly in the arrangement of directions. Whether placed horizontally or vertically, the intersection point must be centripetal. When the V-shape is used alone, the picture is unstable, but when used twice, the picture not only has centripetal force, but also has a sense of stability. The foreground is generally composed in a positive V-shape, and the frame structure with it as the foreground is more likely to highlight the main body.

6. Concentrate on the central combination of strength

Central composition is also often called circular composition. With this composition method, a strong impression film can be taken, which is stable and concentrated. The existence of this composition method is based on the concrete form of the subject and people's imagination, thus forming a circular impression; Alternative

7C-shaped combination

Glyph composition has the characteristics of curvaceous beauty. Photographers should pay attention to arranging the subject in the gap of the glyph when shooting the subject in this way, so that the viewer can follow the C-shaped arc to the subject. In the specific shooting process, the direction of C-shaped composition can be adjusted at will. Under normal circumstances, it is mostly used for industrial, architectural and other topics.

8, horizontal line composition and vertical line composition

Horizontal line composition can make the picture quiet, broad and broad. In the actual shooting process, a single horizontal line, such as the horizon, often appears in the picture. At this point, the photographer should pay attention to the placement of a single horizontal line, because if the horizontal line is improperly placed, it will have the effect of splitting the picture.

When multiple horizontal lines fill the picture, the photographer can arrange the main position on a certain section of some lines, so that some horizontal lines will have the effect of changing the broken line. This method can not only highlight the main body, but also play a certain decorative role in the picture.

9. Diagonal composition

Diagonal composition is a very famous composition expression method. Diagonal composition In a picture, there are two kinds of diagonal relationships formed by lines, one is the diagonal effect of a two-dimensional picture in an intuitive sense. The other is the stereoscopic effect, which can make the picture have a strong sense of movement and show a certain sense of depth. Its linear perspective will turn the subject into a diagonal line and guide people's eyes to the depths of the picture.

In the specific photographic composition, in addition to the obvious diagonal lines, there are also diagonal lines that people feel visually, which are expressed as visual abstract lines produced by the shape, tone and light of the body. Therefore, the grasp of linearity is the key to the use of lines in photographic composition.

10, composition of confluence line

Convergence line refers to a line that converges to a certain point in the picture, which can be a real solid line or a visual abstract line. The convergence line can strongly express the sense of space in the picture, making people feel the three-dimensional sense in the two-dimensional plane picture. The sharper the convergence line in the picture, the stronger the sense of depth of perspective.

Because a wide angle can produce a perspective effect, a stronger perspective effect can be achieved by adjusting the focal length of the lens and choosing a suitable shooting angle. When shooting people or other subjects, photographers can consider placing the subjects in the center of the convergence line, thus playing a certain role in visual guidance and achieving an effect of "forcing the viewer to look".

1 1 straight line curve

Include regular curve synthesis and irregular curve synthesis. Curves symbolize softness, romance and elegance, which will give people a very beautiful feeling. In photographic composition, curves are widely used, such as human body, which mainly presents the curvaceous beauty of human body. There are many ways to express curves. Photographers should pay attention to the general axis direction of curves when composing with curves.

It can use diagonal form comprehensively. S-type, horizontal and vertical, etc. When using curves and other lines comprehensively, the effect can be highlighted, but the problem that comes with it is more difficult to grasp.
