What does dichotomy mean? Draw it.

Dichotomy is actually dividing the dark side-polishing. Lighting needs to have a certain understanding of light and shadow and the structure of objects, and needs special practice. After illumination, the color is superimposed to distinguish the change of color from the change of the picture, and then the highlight material is processed and some tones are made in the picture to complete the picture.

Basic knowledge of dichotomy steps.

First: understand the light source.

Generally speaking, it is good to determine the position of a light source. Depending on the picture, it can come from multiple light sources, but when practicing, one light source is enough to draw the picture. Determine the light source, including what is light. Know what light your photo needs. Natural light source or artificial light source.

Where does the direction of light come from? Where is the reflection position in the top light, side light and bottom light? You should know the influence of different light sources on the picture.

Second: Understand the influence of structure on light.

The general structure of shadows on light and shadow is occlusion. The shadow shape formed by light and shade determines the structure. Therefore, light, shadow and structure must be understood and practiced. Regarding the relationship between structure and light and shadow, in fact, the most intuitive is the plaster body in the sketch.

In dichotomy, the most basic point is to understand the structure of the object and the shape of the shadow area. In the process of painting, the generalization of shadows is simplified. Even if the area is beautified for the sake of the picture, the viewer must see what the picture structure is like.

Third: massive learning.

Any step is inseparable from learning. Whether it is appreciation of exquisite works or reference to pictures. Learning, all in sync. Learning structure. It's not just the chest and legs. It's about all the composition of the picture. The proportion of the characters, the five senses of the characters, the decoration of the characters, the costumes of the characters, and all the structures of the background.

The correct structure can express the comfort of the picture. The structure is correct, the shape is beautiful, and even adding a small amount of shadows can improve the integrity of the picture.
