Painting skills of blackboard newspaper
(1) direct drawing method
Direct drawing refers to drawing directly on the blackboard with chalk. This painting method is characterized by the positioning of pens and pens, interlocking, non-repetition, fast painting speed, vivid picture and one go, which can give full play to the characteristics of chalk line drawing, color points and color blocks and create images. The painted picture has few layers, concise summary, vivid and clear brushwork and is very decorative. Using direct drawing, we should first clearly describe the structure, proportion and position layout of the object, and then gradually improve it from the whole to the part. When writing, you should be accurate and decisive. According to the flexibility of your wrist, use the strength and angle of your pen to control the changes of points, lines and surfaces. Make the picture reach a rhythmic aesthetic feeling. Direct drawing is to shape the image of the screen with points, lines and surfaces, which can be derived from line drawing, line arrangement, point drawing, flat drawing and line drawing. These pictures are often used in blackboard newspapers.
(2) Kneading method
Rubbing is the most commonly used and important method in blackboard newspaper. This is a decorative and painting technique. In the blackboard newspaper, it can play a vital role in drawing chalk, doing title calligraphy or decorating borders. Therefore, the producers of the blackboard newspaper should master it skillfully and use it flexibly, so that the blackboard newspaper can produce better results and more ideal colors.
The rubbing method is to rub and smear the color drawn by chalk on the blackboard with your fingers and palms. Under the pressure of fingers and palms, the toner is rubbed back and forth, so that the color particles are evenly distributed and the colors are mixed and blended. Using rubbing method, the chalk drawn can be thick, bright, harmonious, natural and subtle, and the texture of brush strokes and board surface is not easy to show.
Color matching or daubing small color blocks by friction is mainly done with fingers, that is, the handle is used as a color matching tool and daubing tool. Therefore, fingers should be divided according to color type, block surface size or subtle parts, so as to avoid the phenomenon of dirty color, fine finger rubbing the big surface and coarse finger smearing subtly. For rubbing a large area of chalk color, you need to use your palm. The method is: use the inner palm on the left, the outer palm on the right, and point up and down. Of course, no matter how you wipe it, you should use the prepared wet rag to wipe the chalk color on your fingers and palms in time to ensure the quality and purity of the color.
Friction method has its own unique characteristics in the color treatment of chalk after coloring. Its form is that the hiding power is greatly enhanced after color wiping, and the obtained color effect is uniform and delicate, without revealing black background texture; When the colors are mixed and blended, the color changes richly, and the connection is natural, and there is no texture of pen marks; Shaping the outline of an object can show a hazy effect of alternating reality and reality, and can make the image of the picture show a subtle and feminine charm.
The application of rubbing method should be carried out according to the needs of the picture, and the effect of rubbing should not be blindly pursued just to emphasize pure techniques, otherwise the image of the picture will be weak, not solid and not heavy. At the same time, we should also pay attention to the way and intensity of kneading, and understand the meaning of kneading, that is, the relationship between chalk powder particles and plate texture is the relationship between adhesion and covering and the uniform distribution of powder; The overlapping of the upper color and the bottom color is a color mixing relationship. In these relationships, kneading cannot be done at one time, so leave room for the next coloring. Friction strength should also be different. If you rub it hard, it will not only hurt your fingers, but also make the texture of the blackboard greasy, leading to slipping after repeated coloring. Therefore, the kneading method should be combined with other blackboard newspaper decoration and beautification techniques, and different kneading methods and techniques should be used to shape a good image and achieve good visual effects.
Erasing method is not suitable for glass blackboard and polymer blackboard (teaching green board).
(3) Multi-layer painting
Multi-layer painting is for single-layer painting. The single-layer painting method mentioned here means that the colors depicting the image start locally, reach the designated position in one step, and then expand to the whole, and do not overlap and harmonize the colors on the painted color layers at one time. Although the single-layer painting method can mix and coordinate the color connection parts through kneading, it still has great limitations in the in-depth description of the image and its expressive force is not satisfactory. Therefore, on this basis, the use of multi-layer painting makes up for the defects of single-layer painting and meets the needs of in-depth description of images and improvement of color expression. Therefore, multi-layer painting is a coloring process in which the depicted objects are superimposed for many times, and it is a painting method to increase the color level of the picture and deeply shape the volume, light and shade and texture of the image.
Draw on the blackboard with multi-layer drawing method, draw the manuscript with chalk line drawing method, gently outline the outline and structure of the object, and the picture modeling should be rigorous and accurate. The use of color should grasp the relationship between light and shadow, texture and tone of the body. The color of the cloth should be spread from black or dark to bright, avoiding the painting step of drawing the bright part first and then deepening the dark part color, which may easily lead to the phenomenon of "powder" or "gray" in mixed color, resulting in cloudy picture and uncoordinated colors. In tone processing, we should set the color according to the principle of "warm first, then cool, then warm first", and realize rich and subtle tone changes by using the permeability, fusion and reversibility of the underlying color; Coordination is vivid and transparent; Unique and natural artistic effect. Of course, artistic expression can also directly spread the color according to the color of the image, and then describe it in depth to achieve the ideal effect.
For the use of multi-layer painting, we should be careful not to rub the color too early, so as not to get tired of the rigid texture. We need to adjust the color relationship of each part of the color layer repeatedly with chalk until all colors are basically adjusted. The rubbing method should be based on the image structure and color trend, gently rubbing to make the colors harmonious, without destroying the original color relationship, and then deeply depict the picture, so that the picture is layered, vivid, stable and harmonious.
