Charcoal pen is a drawing pen with charcoal as the refill, and its color is thick black. Its main characteristics are poor adhesion, easy powder dropping and high friction with paper, so don't erase the rubber. However, the drawings made with charcoal are relatively loose at the same time, and are generally used for sketch and portrait training.
Pencils are classified into 13 grades according to the hardness of the refill, which are distinguished by English letters H and B.
H in the pencil means Hart in English, and B means black. The larger the number before b, the darker the pencil color, for example, 6B is darker than 4B. The pencil is HB, 1B-8B. In sketch learning, we often use 4B, 6B, 8B, etc. Lighter pencils such as 4B are suitable for sketching. The pencils 6B and 8B can be painted in light and dark colors to save drawing time. Drawing pencils are suitable for beginners.
There is such a one-sided understanding among the candidates that sketching with charcoal (charcoal pen) is faster. I even think that the charcoal used in the exam took advantage of my grades.
In fact, the use of pencils and charcoal has its own advantages and disadvantages. The key is that the user of the tool should master the performance of the tool and foster strengths and avoid weaknesses.
Drawing for 3-4 hours, I prefer to use a pencil, because the advantage of pencil sketch is that it can arrange lines in different directions and show different textures, and pencil sketch can draw rich color changes.
Especially when sketching still life, it is best to use a pencil, because the inherent color, hierarchy, texture, space and shape of a group of still life are more complicated than the head portrait. Using charcoal, it is easy to make the picture empty, dry and stiff.
Charcoal sketch is really easy to produce results. This is because the color of charcoal itself is much darker than that of graphite pencil, and charcoal can draw a certain range of color blocks at once. But for beginners, sketching with charcoal pen often makes the picture opaque and empty, which easily covers up the structural problems in sketching. When the viewer looks at these paintings roughly, it is not easy to find problems, but when he carefully tries to figure out these paintings, it will be full of loopholes.
It can be inferred that if the time for correcting sketches is prolonged, the score of pencil drawing papers will definitely increase. This may be the reason why most candidates like to draw with carbon pencils. Novices who blindly use charcoal will cover up mistakes and expose problems without mastering sketch techniques, which is unfavorable to the picture effect and undesirable.
Of course. Charcoal does have the advantages of charcoal, especially in large-scale relations. It has obvious advantages over pencils and is relaxed as a whole.
As for using pencil or charcoal pen, I suggest you learn from the teacher yourself. When the teacher teaches charcoal, you learn charcoal first, and when the teacher teaches pencils, you follow suit. As long as you can skillfully use either one, the second one is very simple for you.
