Techniques and methods of sketching

Techniques and methods of sketching: proper composition; accurate proportions, grasp the basic structure of the human body; dynamic and natural, emphasizing dynamic lines; pay attention to the use of pens, and the lines are dense and dense; pay attention to the overall sense and emphasize the artistic expression of formal beauty. .

1. Proper composition.

The purpose of this step is to require candidates to clearly know the composition skills required in a specific environment and the reasonable layout of the picture, that is, the location is appropriate and the overall harmony is harmonious. In the entire teaching system, composition is the first step to draw a good sketch.

2. Accurate proportions and master the basic structure of the human body.

Speaking of proportions, here again the basic structure and dynamics of the human body should be emphasized. For example, the basic proportions of the human body: taking the head as the basic unit, the distance from the hairline, mandible, chest line, and navel is defined as 3 head lengths, and the umbilicus to the pubic symphysis is one head length. The patella-pubic symphysis line on the sole of the foot is 4 heads long, and the pelvic line to the navel is half a head long.

Sitting five (when producing the proportion of the sitting posture, the upper body basically remains unchanged, and the place where the proportion changes is between the pelvis and the patella), and sitting three and a half (observe the proportion according to the dynamic changes of the character). This is the second step to draw a good sketch. This step emphasizes the need to master and understand the basic proportions of the human body proficiently in the daily training and learning process.

3. Dynamic and natural, emphasizing dynamic lines.

Master the two lines that control the movement of the human body: shoulder line and pelvic line. The shoulder line refers to the line connecting two shoulder points. When the human body undergoes dynamic changes, the two lines, the shoulder line and the pelvic line, will form an inverted figure. After we fully understand this law, we can skillfully grasp the basic characteristics of character movement.

Proportions and dynamics are top priorities in the process of sketching learning. We must master the basic knowledge, proportions and skills of human body structure, understand the growth rules of character bones and muscles, and the effects of body movement. Make a clear judgment on the energy. He is good at grasping the basic characteristics of objects and paying attention to the twisting relationship of each turning point.

4. Pay attention to the pen and make sure the lines are dense and dense.

The bone method emphasizes that when using lines, it should be based on the shape changes of the object as a support, and be good at grasping the essence of the object, that is, the skeleton. When using lines in sketching, you should also pay attention to the interpenetration, selection and refinement of lines, and pay attention to the contrast, changes and rhythm of lines (such as weight, virtuality and solidity, square and circle, straightness, density, thickness, length).

Smooth lines can enhance the expressiveness and vividness of the picture. The ingenious combination of the characteristics of the lines and the physical structure is an important condition for the sketch to achieve vivid charm. Of course, sketching that combines lines and surfaces is more conducive to enhancing the layering of the painting.

5. Pay attention to the overall sense and emphasize the artistic expression of formal beauty.

The overall effect mentioned here mainly refers to the artistic effect produced by the author's rhythmic interweaving and layout of the proportions, dynamics and shapes of the painted objects. Sketching is an instant encounter, with a certain degree of contingency. It is precisely because of this contingency that the beauty of the moment, including the dynamics and expressions, must be expressed when painting.
