1. Sketch in a broad sense refers to all monochrome paintings; Sketch in a narrow sense refers to the painting training process used to learn art skills, explore modeling rules and cultivate professional habits. Art is a means to express things. The foundation of art is modeling, which is a complex labor carried out by people in a natural way and a special skill that needs long-term training. Artistic modeling is not only to shape isolated and static object forms, but more importantly, to express the organic relations of various forms in objects. To master the method of artistic modeling, we should not only restore people's natural way of thinking and operation, but also study the formal characteristics of natural objects and understand their changing laws and conditions. Sketch is the best way to solve these modeling problems, which has been fully proved in the practice of artistic modeling. Therefore, sketch is called "the foundation of plastic arts".
2. English sketch.
3. Draw a line with charcoal, pencil, pen, etc., and draw a monochromatic picture of light and dark objects. , also known as sketching. Sketch is the basis of all painting and a necessary stage in the research process. ("Artist" magazine on sketch-Xiao)
4. Sketch usually refers to methods that can leave traces on a plane, such as crayons, charcoal pens, pens, brushes, ink and paper. Others include wear and tear caused by wet clay, ink-stained cloth, metal, stone tools, containers or cloth covers. (Encyclopedia of Artistic Vision)
5. Outlines and lines are the general names of sketches. Sketch has a sense of natural law, which the viewer can feel from the process of appreciation. Different strokes create different lines and cross relationships, including rhythm, active and passive surroundings, plane, volume, tone and texture.
6. Sketch is a kind of formal artistic creation, which uses monochrome lines to express things in the intuitive world, and can also express ideas, concepts, attitudes, feelings, fantasies, symbols and even abstract forms. It does not pay attention to the whole and color like painting, but to the structure and form. (Encyclopedia Britannica)
7. In the book Dictionary of Western Fine Arts (published by Lion Book Company), there is only one explanation related to sketch. It is considered that the sketch of a work or a part of a work is the artist's research and discussion on key points such as light and shadow, composition and the scale of the whole picture. It is a preliminary composition of the whole painting or one of the paintings. The sketch of a landscape painter is usually a small and quick record to show the lighting effect of the landscape and prepare for the idea of repainting in the future.
8. Sketch is a kind of expression with lines and faces. Every object has three parts under illumination: light and dark. From the deepest to the brightest, it is: the dividing line between light and dark, dark, reflective, gray and bright. When painting, the bright part should be as dirty as possible, and the dark part should be as stuffy as possible (that is, there are too many lines without gaps and reflective parts).
Sketch is the inevitable foundation of other arts, especially watercolor, oil painting, printmaking and sculpture (relief), and it is also the necessary foundation of graphic design. Although sketch is considered as a two-dimensional art, it does not need color and three-dimensional space, but it also implies both.
Definition of Sketch (from He Kang Teacher's Manual)
French design, English painting, Chinese sketch. Sketch is to describe the position of external objects in space on a given area or plane material (paper, cloth, etc.). ), and through this training, we can master the light and dark levels and basic images of objects.
Therefore, in the process of sketching practice, sketching must show the body observed by one's eyes concretely and subtly with the help of light and shade and brush strokes. In addition, sketch can also be interpreted as all efforts between "being" and "painting", which is called "descriptive power of painting". For example, when depicting still life on the table, we can not only find the different colors of still life, but also find the sense of security on the table, the harmony between backgrounds, and the complex factors such as modeling, color, lines, texture, sense of quantity, sense of existence, sense of space and dynamic sense are intertwined to form a beautiful order. Painting is to turn those natural orders into picturesque ones, which is also the meaning and purpose of sketch.
At the end of 19, European art completely liberated the description of three-dimensional form and color due to the different pursuit and discussion of the artistic essence of post-impressionism and cubism party, so it also changed the traditional sketch training mode. In some countries, such as the Fine Arts Department of the University of Paris I, France, the course of "Sketch" has been replaced by "Two-dimensional, Monochrome and Multicolor Research". In this course arrangement, there is more space for sketch and more flexible materials. Students can use all kinds of media to practice two-dimensional modeling at will. Therefore, in addition to the basic concept of sketch, we should give more flexibility and flexibility in the training of sketch media, so that the training of sketch can not only match the artistic trend of thought, but also show stronger vitality and wider expressive force.
Sketch is an idea. It is also the basis of all graphic behaviors, especially painting. Up to now, sketch has been regarded as a special technique of expression, including line description, light and shadow, emphasis, tone and so on.
Sketch refers to the basic expression in painting. Because the main modeling elements of painting are lines and colors, if you want to play an infinitely beautiful scene in a limited two-dimensional space, you must skillfully use modeling techniques to achieve arbitrary results. Therefore, sketch is a record made by a painter who observes, experiences, imagines, chooses and reorganizes beautiful ideas with the simplest tools.
Because we focus on the process of painting development, there may be various tentative experiments, so the content and form of sketch expression are also diverse and rich.
