How to master the brightness change in sketch still life painting.

The lightness relationship when sketching still life is influenced by the following factors:

1, the change of the inherent color of the still life itself forms the rhythm change of the brightness of the whole picture.

2. Sketching is to think that the light source made in nature shows the relationship between light and shade of objects. Then the way to reveal the shape in our sketch is to summarize the rich light sources with three facets and five tones. To observe an object, we must first look at black, white and gray, which are three color levels and can be subdivided into five tones. However, the basic requirements for us to roughly simulate the physical sense of nature are three major faces and five major tones, so the key to the five major tones is the boundary between light and shade. He also used light to indicate a rich surface of the structure, which is a key surface, and this surface also has its shape. It is necessary to find the shape of the dividing line between light and darkness to reveal the structure of this body. The dividing line between light and darkness is a very vivid statement. It's actually a face. Judging from the black, white and gray composition of the whole picture, the dividing line between light and dark should be said to be a face with heavy objects on the picture. Pay attention to the understanding of black, white and gray. First of all, black, white and gray are the color levels of a picture, and the brightest level also includes the color changes of black, white and gray. The gray levels in the middle are the same, including black, white and gray, so understanding can enrich our picture hierarchy.

3. The intensity and direction of light have a great influence on the shape and space in the picture, thus affecting the brightness and rhythm of the whole picture.

4. The pattern in the picture can not only define the form and space, but also have the function of decoration, and the change of its brightness directly affects the change of the rhythm of the picture.

5. The application of different tools and techniques in painting, the brightness of the picture is closely related to the performance of the picture texture. We should choose the appropriate tools and expressions according to the content of the picture.

6. Brightness plays a leading role in the emotional expression of painting, and forms a unified and harmonious picture effect through reasonable balance, contrast, pattern and rhythm. From the brightness of the picture, we can divide the colors of the sketched still life into: high color (the darkest relationship between light and shade), middle color (the fifth order in the middle of the nine-order brightness table) and low color (the dark part that is not darker than middle gray on the brightness table). In our usual sketch painting, we usually use the method of full brightness to draw the brightness relationship of the picture, so that the name of the picture will be rich and harmonious.

Analysis steps of still life sketch

1. Make a reasonable composition according to the painting object, and pay attention to the sense of space and connection between objects. Then lay out the background, projection and dark tone in a large area.

2. Determine and distinguish the relationship between black, white and gray.

3. Determine and distinguish the spatial relationship, sketch relationship and sense of volume of objects in this step.

4. Distinguish the relationship between the object, the background and the countertop, and soften the tone in the picture with a pen or paper towel for the next modeling.

5. Delicate the wonderful parts of objects, but pay attention to the spatial relationship between objects.

How to master the brightness change in sketch still life painting. Bian Xiao said here that the attitude of sketching not only cultivated the ability of description, but also cultivated the ability of modeling. Finally, only sketches can be appreciated as works. Bian Xiao will continue to update more basic sketch knowledge, introductory tutorials, learning skills and so on. You can learn more knowledge and enrich yourself.
