Learning sketch is to master the basic knowledge of painting, but also to exercise the ability of feeling and expression. So we should have a solid sketch foundation. No matter what style of oil painting, a solid sketch foundation is the first element. Even a simple sketch, an understanding of modeling and structure sketch's understanding of sideline and silhouette can outline the shape of this object and make it three-dimensional, and the light and shadow of sketch plays a very important role in oil painting.

Oil painting uses color to shape the image, and color is the main means of expression of oil painting. In oil painting, sketch is contained in color, and the physical structure, light and shade level, spatial relationship and texture of objects are all expressed through color. Oil painting tools have obvious advantages in using color and expressing color, and their expressive force is rich. At the same time, the requirements for color are stricter and higher.

From the perspective of the history of oil painting, it is also a process of continuous enrichment and development of the expressive force and importance of color. We are now exposed to a more systematic and scientific theory of painting color sketch, which can be said to be mainly developed and summarized in oil painting practice. Therefore, it is generally believed that color is the central topic of oil painting. Learning oil painting is to focus on the laws of color modeling, cultivate a keen sense of color, and master the correct scientific methods of observing, analyzing and expressing color.

Learn three skills of oil painting;

1, transparent drawing

/kloc-Before the 9th century, transparent painting was basically the basic technique of European oil painting. This technology has many steps. First of all, we should use basic materials to establish our ideal sketch relationship or texture effect on various color negative, then dye with transparent pigments, and finally finish.

It is very simple to understand, that is, one layer of color covers another layer, and the color below is like a piece of colored glass, instead of mixing two colors to produce a third color. The third color is the result of visual harmony, not direct physical harmony.

2, thick coating method

Thick paintings are more willful than transparent paintings, and thicker colors or colors can be superimposed under the condition that the pigments are not dry. The purpose of thick coating is to highlight the key points and shape the texture. The superimposed three-dimensional entities bring a heavy appearance to the oil painting.

You're welcome to this technology. It is more suitable for rough and solid sketchpad, because it is too thin or too weak to support his thick paint layer by layer, and most of them use brushes or scrapers, such as small brushes, which are impossible to carry at all. Rembrandt was the first artist to use "thick painting". In his works, the bright part of the face is very thick.

3. Direct drawing

Direct painting is the most commonly used technique in oil painting, also known as direct coloring, that is, after drawing the outline of an object on canvas, it is completed at one time with the help of the concept of color sense or image quality. If there is anything incorrect or flawed after painting, you can scrape it clean with a knife and continue to paint it, similar to thick painting. Even in the process of painting, the use of pigments is relatively strong, the color saturation is also high, and the brush strokes are clear, which is easy to cause people to sing down the content of the picture.
