Experience the charm of line composition with depth and movement

Lead: Line is an important part of composition. People's eyes often move with lines, whether it is open lines composed of roads, straight trunks and rows of telephone poles, or indirect lines hidden in the outline of shapes, tones and colors.

First, the basic knowledge about lines

1, people's understanding of lines

Mysterious sense of lines, our ancestors were one of the earliest nations in the world to use lines as artistic expression means, even dating back to the Neolithic Age 7500 years ago. At that time, all kinds of painted pottery decorations were outlined with lines. In the Yin and Shang Dynasties, there were simple and straightforward Oracle Bone Inscriptions and rounded hieroglyphics, indicating that people discovered and used line art very early.

Line is the external form of objective things, which restricts the surface shape of objects. Every existing object has its own outline shape and presents a certain combination of lines.

For example, the square table and the long main cabinet have edges and corners, faces and dividing lines, spheres and columns have isolated lines, trees have vertical lines, rivers and rocks have curves, and everything in life, such as cars, boats, trees and melons, has its own shape and contour lines, and different movements of objects also show different line combinations. The line structure of standing people and running people is different. Because people have a deep impression and experience on the line changes of various objects and moving objects along the outer contour in their long-term life, conversely, people can associate the shape and movement of an object through a certain line combination.

Therefore, all plastic arts attach great importance to the generality and expressiveness of lines, which is an important language of plastic arts.

2. The function of the line

The function of lines can be summarized as the following three aspects:

A, lines can act on the overall structure of the picture and the overall posture of the main image. Whether it is the sea, forest, mountain or deep valley, we see natural phenomena, and according to their characteristics, we choose horizontal, straight and oblique line forms to play their main role in the picture structure.

B, lines can create different texture, sense of quantity and sense of space by depicting details such as subject, companion and background.

C-line also plays an important role in creating the melody, rhythm and artistic conception of a work.

Line is not an objective entity, it is just the contour lines of various objects formed by the action of light, lines formed by different shades of dividing lines and too many color blocks, and even nonexistent human vision and intermittent fuzzy dotted lines. Most of these different lines can only be seen later in the work. If you don't carefully analyze, observe and experience when you are engaged in photography creation activities in real life, you may ignore or be unaware of the existence of lines. Therefore, we must exercise our photographic eyes and make full use of lines to complete composition.

3. Characteristics of lines

We summarize and analyze the characteristics and functions of lines, which is very helpful for our photographic creation. Lines have their own different characteristics:

? horizontal line

Horizontal lines can create a balanced mood (lack of change). This line is usually used to express the feeling that a painting, or a part of a painting, was frozen at that moment. When a photographer wants to express an eternal feeling, he can use a horizontal line. In addition, the horizontal line can also be contrasted with the dynamic picture part. Examples can be found in buildings, skylines and falling objects.

? vertical line

Vertical lines can inject stability and calm into the picture. When creating a sense of stability, vertical lines are similar to horizontal lines, conveying a sense of texture and eternity. Examples can be found in stone piles, telephone poles and buildings.

Making good use of vertical lines can also produce a sense of tranquility. For example, trees in foggy forests and ancient fences on grasslands are all similar examples.

? Maomaojiao

Conveying the movement also makes the photos more dramatic. Therefore, diagonal is a powerful tool. This power lies in its ability to catch the attention of the audience. The audience's line of sight will involuntarily move along the diagonal. Slant lines can be not only entities such as streets and walls, but also colors. For example, in photos of flowers, diagonal lines of colors can add drama to the photos. Examples of diagonal lines are endless: roads, rivers, waves and branches.

? Sawtooth lines and irregular lines

Lines and irregular lines, our ability to express emotions and feelings is through going up a flight of stairs. Diagonal lines give us a sense of movement, while zigzag lines and irregular lines make us feel uneasy, nervous or afraid. Excessive use of zigzag lines and irregular lines will bring negative feelings to the audience (or it may be deliberately done by photographers).

Therefore, it is a tool used by photographers when they want to create troubles and anxiety for the audience. Tree roots, crocodile teeth, bare peaks and twisted metal remains are all examples.

? Guide the line of sight

Also known as convergence line, this method is simple but has strong visual effect and stronger ability to guide the audience's line of sight. When using such lines, you should follow two rules.

First, make sure that the lines always point to the most important theme in the picture. Because let the audience directly notice.

Second, make sure the lines don't point out of the picture. The lines outside the painting will take the audience's attention away from the photo. This will weaken the impact of the picture and even make the audience lose interest in the photo.

Common places are roads, rivers and railways. For example, you can go to Tai Po, where you can exercise in the Railway Museum and Lincun River.

Second, the use of lines.

1, with a certain line structure to convey feelings.

In plastic arts, lines are an important lyric means. Because people have accumulated deep impressions and feelings about the line structure of some objects in long-term real life, as long as they are photographed, they will associate with a certain line structure, thus stimulating the corresponding emotional color. Artists attach great importance to the lyric ability of line freeze-frame in their long-term artistic practice. In art theory, the expressive force of lines is described in detail as follows: horizontal lines are stable, vertical lines are lofty, curves are beautiful, radiation is unrestrained, and diagonal lines are dynamic.

A photographer should have a poet's mind and take the line structure of various objects in real life as the object of life. Trees, flowers, mountains, stones and other natural objects, we should carefully study their shapes, postures and the extension direction along the contour line, and express our feelings with their various shapes.

2. A painting should choose and extract representative lines to express its content and infect the audience according to the characteristics of the subject matter.

Any art is not a naturalistic copy of life, but a generalization and refinement of life, and photography is no exception. All the scenes selected on the screen by the frame must be selected, arranged and refined by the author, and the most important thing is to use lines. Clear and concise line forms are presented in the picture, giving play to the expressive force and generalization of the main line.

3. Use lines displayed in characteristic moments to express actions and plots.

The shape, posture and contour of moving objects are constantly moving and changing, so extracting the line structure of moving objects is of great significance for grasping the time, in addition to other modeling methods. At different moments, the line structure presented by moving objects is different, and its modeling expressive force is also different.

Using lines is an effective way to improve photographic composition. As long as used properly, lines can greatly enhance the impact of photos.

Lines will affect composition in two ways. First of all, lines help to create emotions and add emotional content to photos. Second, lines can guide the audience's line of sight and focus their attention on the picture. When dealing with lines, there are several ways: horizontal line, vertical line, diagonal line, sawtooth line, irregular line and guide line.

The use of lines must be conducive to the expression of the theme, closely related to the content, and can not simply pursue the line effect without the content.
