Sketch basic knowledge correlation

Sketch is a kind of monochrome painting, using charcoal pen, pencil, pen and so on. Used to draw light and dark objects with lines. Monochrome watercolors and monochromatic oil paintings can also be counted as sketches; China's traditional line drawing and ink painting can also be called sketch. Generally speaking, sketch diversification refers to pencil drawing and charcoal drawing. Sketch is the basis of all painting, and it is a stage that must be passed in learning painting art. Sketch usually uses methods that can leave traces on the plane, such as crayons, charcoal pens, pens, brushes, ink and paper. And other wear caused by wet clay, ink-stained cloth strips, metal, stone tools, containers or cloth surfaces.

Outlines and lines are general terms for sketches. Sketch has a feeling of natural law. Different strokes create different lines, intersecting relationships and rhythms, active and passive surroundings, planes, volumes, tones and textures.

Sketch is a formal artistic creation, which uses monochrome lines to express things in the intuitive world, as well as ideas, concepts, attitudes, feelings, fantasies, symbols and even abstract forms. It does not pay attention to the whole and color like color painting, but to the structure and form. 2. the status of sketch sketch is an independent art with independent status and value.

Sketch is the inevitable foundation of other arts, especially watercolor, oil painting, printmaking and sculpture (relief), and it is also the necessary foundation of sketch for 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. Sketch is the final result of the painter's work, and it can also be used as the basis for copying or copying, but its nature is unique. Although all kinds of arts do not necessarily need to draw sketches first, sketches are the basis of all decorative arts. When drawing, the outline is often drawn as a draft in advance, and then rendered in color. When a work of art is finished, sketches are often hidden or destroyed. So sketching is just a technical preparation. By the end of 14, sketch is no longer just an accessory, but an independent art, and its scope of expression is very wide: it can express volume, space, depth, essence and action. After the Renaissance, sketch not only has a practical position, but also has become a kind of art that can represent human creativity. 3. Sketching tools

There are many kinds of sketching tools, such as stone pen, charcoal pen, iron pen, chalk, writing brush, pencil and pen. There are also paintings of diamonds and diamonds. Different tools are related to the nature and composition of sketch, and tools will also affect the painter's mood and skills.

The choice of tools depends on the artistic effect that the painter wants to achieve. Generally speaking, dry pen is suitable for making clear lines, and ink pen is suitable for expressing planes; Exquisite strokes can be brushed with a brush, and vast fields can be outlined with a pencil or chalk. Charcoal pen can be used for both. From the size of the work, large-scale sketch works are suitable for drawing with charcoal pen, and the outline and carefulness can be carefully studied and analyzed for a long time. As for pencils, they are suitable for smaller sizes. There are few large pencils, while pen-and-ink drawings are even smaller, and they are often used for illustrations.

The monochrome performance of sketch makes the tool very random, and it can often be used comprehensively to create a variety of picture effects, so it is a very broad world. (1) Pencil Pencil is the simplest and most convenient tool. Beginners often start sketching with pencils. The main reason is that the pencil can be very accurate and clear in line modeling, can be modified at will, and can be used to engrave depth and details, which is due to strict physical requirements and in-depth and repeated research. At the same time, there are many kinds of pencils, hard, soft, deep and light, which can draw more colors. The color of the pencil is also convenient to show many silver-gray levels in the tone, which is effective for basic training operations such as plaster and is easier for beginners to hold. So it is more suitable for the initial application of basic training. The existing domestic pencils are divided into two types, with HB as the center line and B to 6B from soft to dark. In order to better meet the needs of painting, we added 7B-8B, which we call drawing pencils. HB has developed from h to 6H, which is mostly used in precision design and other majors. Because there are many kinds of pencils, they can show rich shades.

(2) Charcoal pens: Charcoal pens should not be brittle or hard, carbon rods should be thoroughly burned, black pens should be soft, and carbon rods should be soft without sand to be top grade.

(3) Pen:

Including all fountain pens with hard tips. You can also draw with strokes used in daily writing. Generally, with a little treatment, bend the nib inward about 30 degrees with small pliers, so that the forward writing is fine and smooth, and the thickness of the reverse writing can be controlled freely. (4) Paper: white, thick, clean paper with paper grain. Pencil drawing paper should not be too thick, charcoal drawing paper should not be too smooth, and pen drawing paper should have a smoother paper surface and a certain degree of water absorption. (5) Sketchpad: Smooth and seamless splint is the best. If you draw standing, you should also prepare an easel. (6) Rubber:

It is best to use flat and soft square rubber. (7) Tools such as pencil sharpener, thumbtack and rag shall be reserved.
