There are many types of sketching tools, such as stone pens, charcoal pens, stylus pens, chalks, brushes, pencils and pens, etc.; drills and diamonds are also used for drawing. The most common sketching tools are: pencil, charcoal pen, charcoal strip, charcoal stick or a single tin tube color, etc. Different tools are related to the nature and composition of the sketch, and the tools can also affect the painter's mood and skills
How to use sketching tools
The use of charcoal strips is characterized by soft texture and color. Pure black, fine powder, changeable layers, suitable for various paper materials (coarse paper, fine paper, soft paper, hard paper), highly expressive and easy to modify, especially for character sketches. force (many masters in the West use this tool). However, the performance techniques are very demanding and difficult, such as: the rhythm of writing, the weight of the stroke, the speed of starting the stroke, the light lifting and pressing, the strength of the wrist, the rotation change of the pen tip and multi-level coverage, the use of block surfaces, front and side strokes The priorities and changes in virtuality and reality shown in the walking of the lines create different textures and structures of various parts of the characters, which is both vivid and thought-provoking. This kind of technical exploration is difficult to master, because each stroke requires deep modeling ability and a full understanding of sketching. The use of this tool should be understood and mastered by students.
There is a qualitative difference between carbon rods and charcoal bars. The texture of carbon rods is harder and the particles are coarser. It is more suitable for painting on smoother drawing paper, because it is not easy to modify, so each stroke must be done with both style and spirit. The expressive power of charcoal rods is slightly inferior to that of charcoal rods in terms of levels, but its characteristics are particularly fully utilized when expressing the elderly. The advantage of the carbon rod is that it can definitely organize the block surfaces and lines, and it is firm and not easy to fade. The picture effect gives people a handsome and unrestrained feeling.
Pencil
In pencil drawing, you usually need to prepare the following tools: pencil (6B-2H), eraser (two kinds of plastic eraser and white eraser) (, wiping cloth (Paper) and paper. Understanding the properties of these materials and mastering the techniques of using them can improve the efficiency of painting and achieve good picture effects. Pencils: Pencils from 6B to 2H. Purpose. When soft lead is used to lay out large tones, it can easily and quickly draw out the tonal differences between light and dark areas and create a tonal atmosphere. It is suitable for describing dark and dark areas, but due to its poor adhesion to gray, it is easy to stain. Hard lead can play a role in processing the texture of the picture, outlining rich lines and expressing subtle changes in bright tones, which is difficult to achieve with soft lead. However, if used with excessive force, it will easily damage the paper surface and destroy the effect of the sketch. If you use soft lead alone, it is easy to make the dark parts dull and greasy; if you use hard lead alone, the deep tones cannot be darkened, and if you repeat it too many times, the painting will become greasy and the paper will be damaged easily. Use the strong points and avoid the weak points to give full play to the advantages of each. When using it, you usually use soft lead to "base" the dark colors, use hard lead to go deep, and press the light colors. Follow the order of first soft and then hard. If the order is reversed, the soft lead will be used. It is not possible to go deep into places that have been painted with hard lead. When the weather is cloudy and rainy, the paper is soft, so it is better to use soft lead. When the weather is sunny, the paper is stiff and the 2B pencil can draw deep tones.
Eraser
There are two types of commonly used erasers: white eraser and plastic eraser. The white eraser has a stronger cleaning ability than the plastic eraser; among the same type of eraser, soft eraser has better cleaning ability. It has stronger cleaning ability than hard rubber. If you want to remove some deep and greasy tones, you must first use a plastic rubber to remove the shiny "putty" on the surface, and then use a white rubber to remove it. In addition, use a knife to cut out the white rubber. Sharp corners or plastic rubber can be used to highlight highlights and small details. It can also be used to draw out a set of beautiful white textures like lines on a gray background: plastic rubber can also be used to absorb large areas of painting. If the tone is overdone, adjust the tone flower part to make the tone transition natural. Use an eraser to rub the gray tone with a certain intensity, and you can also make the local gray tone darker.
Wiping paper
Cloth (texture should be soft and dry) can be used to lighten the deep tones that are overdone; used to rub the deep tones to remove greasiness and make them rich and soft; Use it to wipe away hard, jumping, and messy pencil marks to soften them; if you use it to wipe gray tones, you can make the gray tones darker. If used properly, it can produce rich effects. After laying the big tone, wipe it again with a cloth to quickly make the tone darker. Become richer, widen tonal differences, and speed up painting. Some authors like to lay out the tone with a pencil and then wipe it with a cloth, alternating between the two. It can quickly create a picture effect. When wiping gray tone, control the change of tone by controlling the strength and time of wiping. In case of blooming phenomenon, you can use a plastic eraser and pencil to adjust it. A rag dipped in pencil dust can also be used. Start with large-sized drawings and cover large areas with deep tones.
White chalk for sketching
It is used to brighten the highlights. Some colored sketch papers cannot erase the highlights at all, or they have been painted with a thick layer, which cannot be solved by erasing. White chalk can be used for sketching, and some expressions of the hard texture of plaster must be brightened with white chalk
Sketch paper
There are many papers that can be used for sketching, commonly used in China There are lead drawing paper, cardboard and watercolor drawing paper. The surface of the lead drawing paper has coarse particles and loose paper, so it is easy to pick up lead and is suitable for short-term painting work. The surface of double-sided white cardboard has fine particles and is relatively smooth, and can display rich tonal changes. In addition, the paper is dense and stiff, and can withstand repeated modifications and engravings. It is suitable for medium and long-term painting operations. The surface of watercolor painting paper has a mesh texture. Suitable for creating some special picture effects.
