That is to say, paint that is not white but diluted with color oil is used for multi-level description. It is necessary to brush the next layer after each layer is dry. Because the color of each layer is relatively thin, it can vaguely reveal the color of the lower layer and form a subtle tone with the color of the upper layer.
This painting method is suitable for expressing the texture and heavy feeling of objects, especially for vividly depicting the delicate color changes of human skin, making people feel that blood flows under the skin epidermis. Its shortcomings are narrow color gamut, meticulous production process and long time to complete the work, which is not easy to express the artist's current artistic creation feelings.
Opaque covering
Also known as multi-level coloring method, when painting, the shape is first drawn with a single color, and then shaped with multi-level colors. Dark parts are often painted thin, while middle tones and bright parts are painted thick layer by layer, or covered or left, forming color block contrast. Because of the different thickness, it shows the rich charm and texture of color. There is no strict difference between transparent and opaque paintings, and painters often use them comprehensively in one painting.
When representing objects in darkness or shadows, transparent masking color method can produce a stable and profound sense of volume and space; The rule of opaque color superposition is easy to shape the body outside the dark part and increase the saturation of the picture color. /kloc-before the 0/9th century, most painters used these two painting methods, which usually took a long time to make their works. Some have painted a layer and left it for a long time, and then painted it when the isochromatic layer is completely dry.
Scraping is the basic usage of oil painting knife. Scraping is generally used to scrape off the unsatisfactory parts of the picture with a blade, or to scrape off unnecessary details or weaken the strong relationship with a knife to relax the tense picture relationship. At the end of one day's homework, it is often necessary to scrape off some colors after painting with a knife in order to dry them in time and continue painting the next day.
When the color is dry, you can also use a painting knife or razor to scrape off the uneven places. You can also scrape off the wet color layer with a knife to expose the background color and show various textures.
Extended data:
The predecessor of oil painting is1egg painting in European painting before the 5th century, which was developed by the Dutch painter Jan Van Eyck after improving the painting materials (1385-144 1). Later generations praised Yang Van Eyck as "the father of oil painting" because he made a unique contribution to the in-depth development of oil painting techniques.
Modern oil paintings mostly use linseed oil to blend pigments and paint on processed cloth or wood boards. Because oil painting pigments do not change color after drying, many colors will not become dirty after mixing, and painters can draw rich and realistic colors. Oil painting pigments are opaque and have strong coverage, so the painting can be covered layer by layer from deep to shallow, giving the painting a three-dimensional effect.
Oil painting has gradually become the main way of painting in the history of western painting, and the surviving western painting is mainly oil painting. With the development of time, oil paintings have gradually come into life. The most famous one is an ordinary woman in Mona Lisa, which is widely circulated. /kloc-In the late 20th century, due to the development of science and technology, many new materials were applied in the field of oil painting, such as acrylic pigments and coatings.
There are two schools of oil painting. The first category is creative works which are mainly based on objective reproduction; The second category is creative works with subjective expression.
The first category, such as Baroque, Locke, Classicism, Academicism, Romanticism, Realism, Realism, Photographic Realism and Impressionism, appeared after the Renaissance, all of which were based on the reproduction of nature and expressed the different thoughts and purposes of painters. Baroque-/kloc-baroque pop from the 7th century to the 8th century.
The original meaning of the word "Baroque" is irregular, twisted and grotesque. Advocating the distortion, richness and sense of volume of movement, its artistic language is strong, exaggerated, dynamic and flashy, which are the characteristics of baroque painting, and its representative is Rubens.
Rocco school-"Rocco" originally meant the shape of a shell. Its artistic style is complex, delicate, slender and sweet, and it was popular in18th century. Its representative painters are Eduardo and Fran? ois.
Classicism and academic school-Classicism is based on respecting the aesthetic principles of ancient Greece and Rome, with symmetrical and balanced composition, solemn and magnificent momentum, exquisite techniques and in-depth description. This is also the principle pursued by the academic school.
As Fasino, the founder of academic school, said, "Beauty is the highest goal of all works of art and an objective nature of things, which is composed of order, harmony, proportion and rules". Its representative writers are Raphael and Angel.
Romanticism-Romanticism originated in the early19th century, and its masterpiece is "Medusa's Raft" by Ji Like. The composition, light, color, dynamics and expressions in this work all show the artist's rich imagination, breaking the horizontal and vertical in classical composition, and the light is soft and even, which makes the picture have a passion. This is also an important element of romantic painting, which pays attention to the catharsis and expression of feelings.
Realism-realistic painting refers to1In the mid-9th century, painters headed by Miller advocated expressing normal visual images and reflecting the essence of life by being faithful to objects. His masterpiece is "Miller's Collection".
Realism and photographic realism-realism, as its founder Courbet said in 1885: "As I have seen, it faithfully shows the customs, thoughts and characteristics of my time. In short, creating art is my purpose. "
Photographic realism is to put life on the screen in the form of photography, such as a close-up portrait of John. It draws a work by taking photos or slides first, and then enlarges it to the cloth at a ratio ten times larger than the real person, showing the details of the object more delicately and realistically, such as every texture and hair on the face.
Impressionism-Impressionism is that painters in the19th century went out of the studio to explore the instantaneous changes of light and color in nature, which broke the traditional concept of inherent color, such as the tree is blue-green, and the shadow is black. It objectively painted the influence of the surrounding color on the inherent color. Its representative painters are Monet, Seurat, Cezanne and Renoir.
If the above-mentioned school of painting is still a faithful representation of nature by painters, but only supplements, emphasizes and develops it, then the second category introduced below is post-impressionism, fauvism, cubism, futurism, abstraction, surrealism and so on. , is no longer a true description of the objective object, but a free creation according to the painter's subjective intention, and most of them appeared after the 20th century.
Post-impressionism-Post-impressionism painters emphasize self-feeling and pay attention to color contrast and the internal structure of things. The representative painters are Van Gogh and Gauguin. This school of painting has had a far-reaching influence on modern western painting.
Fauvism-Fauvism expresses its inner passion with exaggerated shapes, strong colors and rough lines, and Matisse is the founder of this painting school.
Cubism-Cubism painting school, the viewpoint of the picture is no longer an orientation, but an all-round performance of things, so that objects can be restored to geometric shapes. Its founder is Spanish painter Picasso and French painter Braque.
Futurist-Futurist painters use colors and lines to express the speed and intensity of movement and their combination and separation in an abstract form.
Abstraction-Abstraction depends on the abstract combination of lines, blocks, surfaces and colors, and has no concrete image. Its representative painter is the Dutch painter Mondl An.
Dadaism-Dadaism has a certain influence on later surrealism, mobile sculpture, pop art and even postmodernism.
Surrealism-Surrealism painting school is influenced by Bergson's intuitionism and Freud's subconscious theory, and advocates expressing people's subconscious and dreams. Representative painters are Spanish painters Dali and Milo.
