Sketch shading problems

In fact, the sketch is mainly to express the relationship between black, white and gray, and the key to the chiaroscuro tone lies in the boundary between light and dark, which is produced by the shape and the light, and is the heavy color block in the object established by the light. If you grasp the boundary between light and dark, you will be able to effectively distinguish between light and dark color blocks. Just watch out for small reflections on the dark side.

Sketches are divided into glossy surfaces. The dark side. Gray side. Light and dark junction line.

It's almost 、、、 to divide these sides

The point is to draw the line between light and dark.

Distinguish between the light side and the dark side.

If you don't know how to copy some of CAFA's works.

As for styling, it can't be good in a day or two. Practice for a long time.

Sketching black, white and gray is important, but the important thing is to be diligent, thinking, researching and analyzing, light and shade is always a general key, lies in the performance of details, mastering the five major tones, copying is also a method, but it also has to be combined with model painting to study and analyze, only care about copying, do not analyze the details of others, in the end it is still useless.

There should be a sense of great light and darkness in the heart! Grasp the overall feeling! Find a whole line between light and dark!

Projections and light and dark boundaries are generally connected! Big feeling is the main thing! Then dive in!

Find some little light and dark relationships!! In the end, it is still necessary to unify on the relationship between light and dark in the first step!

Find the dividing line between light and dark and then the contrast relationship with various objects Each object is mainly divided into dark side Bright side and reflection Reflection also depends on the strength of the object's reflection on other objects I don't know if the landlord is asking about still life or people?

Pay attention to the wiring method, pay attention to the big relationship, and pay attention to the change of virtual and real.

What should be bright will be revealed, what should be black will be deepened, and don't be afraid of bad painting.

Fascinated by the eyes, first the whole and then the part.

<> "The relationship between light and dark is a very important part of sketch painting, and its most basic function is to express the relationship between volume and space. The relationship between light and dark is divided into five major levels, which is often said: "five tones of light and dark".

The five tones of light and dark include: highlight, the brightest point on the light-receiving surface.

Bright surface: refers to the layer between the bright and dark gray surfaces of the light-receiving surface.

Gray surface: refers to the level between the light side and the boundary between light and dark.

Light and dark junction: refers to the turning point of the light and dark sides, and the general light and dark junction is the heaviest place.

Dark Side: Contains the backlit side of the object, reflections, and shadows.

These five levels can actually be summarized into three levels: the light side, the gray side, and the dark side. Of course, there are more and finer levels in these five tones, which can be summarized and distinguished according to the degree of detail of the painting.

Let me first explain the relationship between light and dark of objects through the cube. You have to have light before you can have light and dark, so I'm going to assume a light source direction for now. The area where the light can shine is called the light-receiving surface, and the place where the light cannot shine is called the backlit surface.

The backlit side includes the dark side and the shadow side, and the lighted side includes the light side and the gray side. The shape of the shadow is directly related to the direction of the light and the occlusion of the object. According to the principle of near real and far virtual, the contrast between the front, especially the junction between light and dark, should be strong and clear, and the contrast behind should be weak and blurred.

Also, the shadow gets darker and clearer the closer it is to the object.

We all know that the earth is always half a world day and half a world night, and the time close to night is morning and dusk, and generally the light is brightest at noon. The same is true for drawing spheres, half a ball is bright and half a ball is dark, the position where the bright part is perpendicular to the light is the brightest, and the closer to the boundary between light and dark, the darker it will be, and these places close to the dark part are called gray surfaces. The reason why the dark area is not pure black is because it is also affected by reflections and other ambient light sources.
