Does the relationship between density and density in sketch mean near-distant density?

What the landlord said is close and distant, which means in perspective. .

Line perspective, also known as "perspective perspective" and single-point perspective, is a method to express the depth of space with certain regular lines, which is characterized by being close to the big and far from the small, close to the distant and dense, and apparent horizon has vanishing points. Photographers often use foreground to enhance their perspective.

There are two main methods to express sketch: line drawing and line-plane combination.

Line drawing is to summarize the outline and structure of an object into lines in the form of a single line, sometimes with decorative lines, which mainly shows the characteristics of the object and conveys the demeanor of the characters. This method is similar to the "line drawing" in Chinese painting.

The line-plane combination method is mainly based on lines, and appropriately matched with flat cables representing gray levels, indicating the brightness or inherent color of objects.

The type of sketch depends on the time and purpose of painting. The one who paints for a long time is called "write slowly", and the time in write slowly is generally less than two hours. Shorter time is called "sketch", and the time is usually from a few minutes to ten minutes; There is also "dictation", which draws from memory when the object has left and changed. In creation, dictation plays the greatest role.

1. Generalization and selection

Those parts that are conducive to the expression of physical structure or to the handling of various artistic relations should be taken naturally, while those that are not clear should be extracted, and those parts that are not conducive to the expression of physical structure and artistic handling should be abandoned without hesitation, regardless of whether they are clear or not.

2. Contrast exaggeration

Contrast is the most basic expression language of painting art, and its application in dynamic sketch of characters has the following aspects.

(1) contrast between density and density:

contrast between density and density refers to the relationship between lines and faces of people in a picture. Its application is closely related to trade-offs, namely, taking it is dense, giving it up is sparse, being dense is complicated, and being sparse is simple. Density comes from choice, and contrast is the basis of choice. According to the characters' dynamics and clothing characteristics, and under the restriction of the big density relationship, the specific density changes are noticed. The ancients said: "Sparse can take a horse, dense is impenetrable", "sparse is dense, dense is sparse" is this meaning.

(2) contrast between excess and deficiency:

excess and deficiency are related to both density and severity. Density is the distance between lines and planes, while the virtual reality is the presence or absence of lines and planes. The ancients said: "Generally speaking, the beauty of reality is born of emptiness." The organizational arrangement of lines and planes should see the blank space, that is, the sparse space. The size of the blank space varies, and the density naturally changes.

Weight is another comparative concept of reality and excess, which mainly refers to the specific changes in the secret, that is, the reality. Light is virtual, heavy is real, light is heavy, and virtual is real. It can express the sense of space of the body structure.

(3) comparison of length:

comparison of length mainly refers to the dynamic sketch of characters completed by lines or basically completed by lines. Where the length of lines is related to density, short lines are dense and long lines are sparse, but this rule is limited to contour lines. The key to the density inside the body lies in the arrangement of lines. There are too many short lines in the overall effect, and the picture effect is easy to break; If there are too many long lines, the picture effect is easy to simplify. Length contrast refers to the corresponding relationship. If it is long, it will be adjusted in a short way, and if it is short, it will be supplemented in a long way, so that the lines will change.

4) Contrast between curves and straightness:

If there are many curves in a painting, it is easy to feel weak, while if there are many straight lines, it will feel dull. There is a curve in the straight, and there is a straight in the curve, so the use of lines will naturally have a sense of relaxation. At the same time, the contrast and change of the melody can also constitute the ups and downs on the edge of the figure. The ups and downs are the derivative states of the straight changes, and the different concavities and heights of the outer edge of the figure can make the lines more aesthetic and expressive, and also make the characters more vivid
