Sketch is for the purpose of expression, which is generally used as a basic sketch exercise to improve students' modeling ability, or as a finishing or local drawing exercise before creation. It is a method to collect materials and practice the unity and density of object image, dynamics, volume, texture, light and shade, space, color, proportion, composition and change. Most painters have a painting prototype before working on an oil painting or mural, and this simple prototype painting is a sketch. Sketch is rarely used to make finished products, but some painters make them in this way, and such finished products are different from draft paintings because this sketch is in addition to the basic skills of prototype paintings, plus the details of light and shadow changes. The purpose of this sketch is also a visual record of the painter.
Sketch is different from watercolor painting and oil painting in expression skills, that is, it pays attention to the expression of lines, and describes the depth of an object with the thickness of lines, regardless of the hue value of the object details. The picture highlights the theme with light and dark contrast, but it also loses the consideration of hue. Sketch has distinct details in light and dark tones, which can show the three-dimensional sense of objects in subtle changes of light and dark.
Angel, a French classical oil painter, created a lot of sketches and single-line works because he thought that the role of color was not the main one, which was different from that of romanticism. China painter Wang Shikuo's famous work "Bloody Clothes" was also created by sketching.
The famous sketch master is the three giants of the Italian Renaissance: Leonardo da Vinci; ? Michelangelo Buonarroti; ? Rafael Sancho; ? Xu Beihong of China (1895- 1953? )。 Rembrandt, Peter Paul Rubens and ilya repin are also sketch masters.
Sketch is also a plastic art, and its purpose is to create three-dimensional shapes on two-dimensional paper. The accuracy of modeling and the scientific nature of internal structure are the most important.

Pencil sketch is often the beginning of sketch practice. Whether it is fine sketch or sketch, you can start with an easy-to-modify pencil. And practice using pencils with different marks. The pencil mark b indicates soft texture. The larger the number in front of the mark, the softer the texture, which can be used to draw darker parts. H indicates that the texture is hard, and the larger the number in front indicates that the texture is harder, which can be used to draw lighter parts.
The drawing paper for pencil sketch can be rough paper, such as 150 pound or 200 pound template paper, and soft glue is preferred.
Common sketch exercises can be practiced through still life sketch and landscape sketch.

Charcoal in charcoal sketch is usually made of wicker. Drawing paper can be made of 150 kg or 200 kg, and can be wiped with soft glue, steamed bread and bread.
Charcoal sketch often takes gypsum as the practice object, because gypsum is a pure object with no color and strong texture change, which can produce obvious contrast between light and shade after being irradiated by light. Beginners often start with avatars.
