The book standard is:
1. Clear lines. (It is necessary to clearly see many lines on the screen)
2. The composition is reasonable, there must be an overall relationship, and black, white and gray should be distinct. (Sketch is made by pencil, and the picture should have three colors: black, white and gray. If the black is black, the white should be left blank.)
3. The book should have the steps of composition, shaping, overall adjustment, etc., and drawing.
4. Explain the grip of the pen and the standard of posture.
To learn sketching, you must first practice lines, so that the lines are straight, the ends are light and the middle is heavy, and the horizontal, vertical and oblique directions must be mastered. The method of holding the pen must be correct (it is not a matter of one day to practice lines, so just practice for about 1 minutes every day)
1. The farther away an object with the same size is, the smaller its shape becomes, so that it finally disappears at one point, which is called the vanishing point.
2. The farther the scenes with the same distance are, the shorter the distance between them should be.
3. A line that is the same height and parallel to the painter's eyes is called apparent horizon.
4. Everything lower than the painter's eyes is under apparent horizon, and you can see it above.
5. Everything higher than the painter's eyes is above apparent horizon. See it below.
6. standing on a broad flat ground and looking ahead, the boundary line between heaven and earth in the distance is called horizon. When looking up, the horizon and apparent horizon coincide, and the horizon is apparent horizon; Looking down, the horizon is above apparent horizon. Horizon is an important basis for processing perspective graphics.
7. See the left side of any scene located on the painter's right
8. See the right side of any scene located on the painter's left.
9. The farther the scenery above apparent horizon is, the lower its position on the drawing paper.
1. The farther away the scenery below apparent horizon is, the higher it is on the drawing paper.
Sketch concept:
It is called sketching that charcoal, pencil, pen, etc. are used to draw a monochromatic picture of light and dark objects with lines. Monochrome watercolors and monochromatic oil paintings can also be counted as sketches; China's traditional line drawing and ink painting can also be called sketch. Generally speaking, sketch diversification refers to pencil drawing and charcoal drawing. Sketch is the basis of all painting, which is a stage that must be passed in the study of painting art. Sketch usually uses methods that can leave traces on the plane, such as crayons, charcoal pens, pens, brushes, ink, paper, etc., and others include the wear and tear caused by wet clay, ink-stained cloth strips, metals, stone tools, containers or cloth surfaces. Outline and line are general terms for sketch. Sketch has a sense of natural law. Different strokes create different lines, cross-cutting relationships and rhythms, active and passive surrounding environment, plane, volume, tone and texture. Sketch is a formal artistic creation, which expresses things in the intuitive world with monochrome lines, and can also express ideas, concepts, attitudes, feelings, fantasies, symbols and even abstract forms. It doesn't pay attention to totality and color like colored painting, but to structure and form. "Sketching is the most basic painting activity. Leaving a note on a plane or drawing a line segment will immediately change that plane and inject vitality into a neutral surface. The intervention of graphics turns the plane into a virtual space and the material reality into a fictional scene composed of imagination. Notes on paper destroy the emptiness of paper, make the plane come alive, and show potential dimensions from nothing. Handwriting and plane * * * participate in the dialogue, exchange positive and negative, and switch the relationship between object and foundation. Lines cut the space on the paper, and also release the hidden or productive energy on the plane. China ancient calligraphers also had a deep understanding of the generative energy of paper. All the possibilities of painting come from the physicality of this picture.
tool selection: pencil sketching is often the beginning of sketching practice. Whether it is fine sketching or sketching, you can start with a pencil that is easy to modify. And practice using pencils to sketch Su Zhi and
pencils with different marks. The pencil mark B indicates that the texture is soft. The larger the number in front of the mark, the softer the texture is, which can be used to draw darker parts. H indicates that the texture is hard, and the larger the number in front of it, the harder the texture is, which can be used to draw the lighter part. The drawing paper for pencil sketch can be rough paper, such as 15-pound or 2-pound die paper, and soft rubber is preferred. Pencil sharpener, thumbtack, cloth wiper and other tools for standby. It is better to use a flat and soft square rubber. Smooth and seamless splint is the best. If you paint standing up, you should also prepare an easel.
(1) Line and line technique The element of sketch is line, but the line does not exist in essence. It only represents the boundaries of objects, colors and planes, and is used as an illusion of objects. It was not until modern times that lines were considered as spontaneous elements of form and independent of the depicted objects. (2) Using lines to form the image sketch of the object is to use lines to form the image of the object and draw it on the plane, which will arouse the association of the viewer through the form of lines. For example, the angle formed by the intersection of two lines can be considered as the boundary of a plane; In addition, adding a third line can create a three-dimensional effect on the picture. Curved lines can symbolize the vault, and lines that meet and gather can express depth. People can get comprehensible images from the changes of lines. Therefore, through the means of lines, simple outline can be developed into exquisite sketches. (3) Distinguishing solid and plane with lines In sketch, lines can be used to distinguish solid and plane. As for color shading, it is to strengthen and distinguish the relationship between the whole and the part. We can use the beginning, disappearance and interruption of lines to draw boundaries and form a plane, or we can make colors go up to the boundaries. The thickness of lines can show the changes of objects, and even light and shadow can be shown by the changes of strokes of lines. (4) The auxiliary of plane technique The line technique of sketch also needs the auxiliary of plane technique. When using charcoal chalk in plane technique, the brush-wiping method can be used in contrast between light and shade. (5) The use of brush painting is more important, because the brush can play the width of strokes and the intensity of strokes, and can increase the sense of space and three-dimensionality. (6) Enhancing Artistic Sketch: Multicolor brushes can also be used as basic materials to enhance the sketch effect and artistic quality.
