What is an uptone? What does tune mean?

Accenting is coloring.

Like building a house, layer by layer, let the boundary between light and dark be the darkest and the bright part the brightest; Let's get the dark part again.

It is also a little brighter, but the dark part is darker than the light part no matter how bright it is; Then use an eraser to grind the dark spots; Remember that the shadow part should also be on at the same time when the tone is up; Make the junction between the shadow and the object almost as dark as the junction between light and dark, and then slowly brighten it up. Remember, a true painter doesn't pay attention to lines, and laymen have to work on lines.

This is mainly to solve a three-dimensional representation of space on a flat surface.

The optical illusion relationship is mainly to understand the direction of movement of the object, and draw lines to organize light and dark according to the direction of movement of the object!! It's hard to explain here, but on the one hand, you have to draw more, you have to understand the reason, and you have to understand the reason for it!! The most important thing is to practice more, there are no fixed rules and regulations, when you draw to a certain amount, there will be a qualitative change, and then you will suddenly realize that painting is a very beautiful thing, and painting is also a process of honing your mind.

Pain and joy.

Remember: when you can't draw, you have to make progress, and you must hold on.

In addition, in the process of painting with light and dark tones, we must first deal with the three major relationships of light surface, gray surface and dark surface, and then further draw richer light and dark levels, which is what we usually call "three sides and five tones". Object tone contrast.

determines the overall effect of the picture. Sometimes if the contrast is too strong, it will feel rigid and stiff, and if the contrast is too weak, it will feel that the tone is too dark. In general, deliberately portrayed transitions should be contrastingly strengthened, while secondary areas should be weakened.

The difference in the inherent shade of the object also determines the difference in the tone of the sketch, dark objects, gray objects and white objects, to determine the difference between the light and dark tones between the objects on the basis of comparison, when painting, the dark and dark ratio, the light and dark ratio, the light and light ratio, the object and the lining ratio of the method to distinguish the various sketch levels, the beauty of the tone itself can arouse people's interest, rich levels, changeable combinations, virtual and real contrasts can produce different rhythms, rhythms.

The most common problem in sketching still life sketching is that the tone of the picture is scattered, and the feeling of the picture is "flower", which is mainly due to the fact that the tone of the object is not whole, and the grasp of the contrast between light and dark is not accurate, especially the depiction of the inherent color of the object is often out of range, improper processing, and discordant tone connection. On the other hand, there are often "dirty and greasy" problems, which are mainly caused by too many erases. In the process of painting, if the pen is too cumbersome, rigid, and the lines are laid out too many times, it is easy to appear "tired", especially if you use a hard pencil repeatedly to paint, it is easier to smudge the picture.

Make the picture bright and not bright, deep not deep, the tone contrast is not loud, weak and lifeless, this situation should strengthen the portrayal of the boundary between light and dark, adjust the contrast between the light and the backlight, draw the dark object enough, brighten the light part of the object, strengthen the contrast between the virtual and the real, strengthen the contrast between the strength and weakness of the front and back, and make unified adjustments. In this way, the picture can be natural and vivid.

Sketching nouns is coloring, and the lines form a relationship between light and dark.

Summary. Sketching on the tone is a complete process, to know how to adjust the tone, how to do it well. There is still work ahead of us.

It is necessary to practice the basic knowledge and performance of line arrangement, understanding structure, knowing light and dark, highlights, and reflections. If the foundation in the front is not good, it is not good, and the drawn things will only feel dirty.

Sketching is a complete process, and you have to know how to improve the tone and how to detect how the spine is good. There is still work ahead of us. It is necessary to practice the basic knowledge and performance of line arrangement, understanding the structure, knowing light and dark, highlights, and reflective socks.

If the foundation in the front is not good, it is not good, and the drawn things will only feel dirty.

Detailed explanation of the sketch on the tone skills 1, when the line is arranged, the direction should be consistent, stroke by stroke, the density is appropriate, 2, it should be light and light, so that the two ends of the line are light, the middle is heavy, do not connect the pen, 3, the direction of the line should be properly considered The block structure of the object, 4, the dark part of the drawing, to change the direction of the line, layer by layer Xuncha Na deepening, do not scribble. The main line is more practice, there is no shortcut to find, grasp the light and dark acres without the handover line, it is easy to show the level and three-dimensional sense of the object, the most taboo line to play the crosshair, to make the line like a tic-tac-toe cross, do not disturb the line, to draw patiently one stroke at a time.

As for the structure of the object, observe more, first of all, we must master the perspective, in order to understand the structure of the object, it is also helpful to look at the structural sketches of the predecessors, the basic idea of playing lines should be to draw the "surface" rather than simply counting the bridge bucket in order to draw the "line", you should be clear about this first. Then the rest is to practice more potato mills, and the main point of the movement is to use the wrist to swing back and forth, not the fingers, let alone the whole arm. For the structural aspect, it is recommended that you start with the volume and consider the structural direction.

Five tones: 1. Specular: the brightest point of the light-receiving object, which shows the part of the object that directly reflects the light source, and is mostly seen in objects with a relatively smooth texture.

2. Bright gray part: the area between the highlight and the boundary between light and dark.

3. The boundary between light and dark: the area that distinguishes the bright and dark parts of the object, which is generally the structural turning point of the object. (The boundary between light and dark does not refer to a specific line, its shape, light and dark, virtual and real will change with the transition of the object's structure.) ）

4. Reflection: The backlight part of the object is affected by the reflected light of other objects or the environment in which the object is located (reflection can make the object more transparent and have a sense of volume).

5. Projection: the dark shadow produced in the space after the object itself blocks the light (with the projection of the heavy color object in the picture.)

so as not to appear floating).

Tone refers to the black and white levels of different brightness of the picture. It is the amount of light reflected by the surface, that is, the depth of the surface. Be good at summarizing and summarizing the level of tone, and different sketch tones reflect different personalities, styles, hobbies and concepts.

Among the three major surfaces, there are many obvious differences according to the intensity of the light, forming five tones. In addition to the bright tones of the bright side, the gray tone of the gray side and the dark tone of the dark side, the dark side is "reflective" due to the influence of the environment. In addition, at the junction of the gray surface and the dark side, it is neither irradiated by the light source nor affected by the reflection, so the darkest side is squeezed out, which is called the "junction of light and dark".

These are what we often call the "Big Five".

The tone in the art is what I said upstairs!

Highlights, bright grays, light-dark borders, dark grays, reflections).

The five tones are the most basic pattern of the change of light and darkness of all objects under a certain light, and the difference ratio of their specific brightness should be compared according to the specific object and the specific light

The order of chiaroscuro in the five major keys is:

Highlights, light gray, reflective, dark gray, light and dark junction line.

The five major tones are divided into five tones in detail on the basis of the three major aspects. The lighted surface is divided into gray surface and bright surface, and some objects still have obvious bright light on the bright surface. On the back there is a dark side and reflections.

Although projection is not included in the five major keys, it is still an indispensable part of the picture.

Intermediate colors, reflections, and black, white and gray are collectively called the five major tones of light and dark, and the five major tones play a leading role in a painting, and the chiaroscuro contrast between them, the change of levels, the strength and weakness of the virtual and the real, etc., are directly related to the success or failure of a work. The lighted surface is divided into gray and shiny surfaces, and some objects also have obvious bright light. In fact, the light and dark changes of objective objects are very different, and each point is different from another point, and the layers are very rich, especially the relationship between light and dark in complex shapes is even more complicated.

The two major parts, the three major aspects and the five major tones mentioned here are only generalizations and inductions from a big perspective, which are conducive to the relative expression of the overall relationship between the forms.

When looking at the light and dark tones of an object, it is necessary to learn to compare them comprehensively, first of all, to identify which are the deepest parts of the object, which are the lightest parts, which are the darkest parts, which are the second brightest parts, and finally which are the middle tones of the philosophy of life. Comparing these five basic tones, the big relationship between light and dark is correct.

The key in ** is the time signature!

Highlights, midtones, light-dark lines, reflections, shadows

Common questions in the five key tones.

The boundary between light and dark: It is actually the handover of the surface and the hue of the surface, not really a line.

Reflective: A part of the dark part, which generally does not exceed the brightness.

Projection: Projection has a shape, and the brightness of the projection is generally separated from the brightness of the object.

Highlights: The brightest part of an object, and the highlights of different textures are different.

Gray surface (middle tone): generally painted last, subjective control of the level of change, easy to paint gray.

The three main sides of the object:

Light, gray, dark.

The importance of the three sides and the five tones:

In the study of basic sketch painting, the three sides and five tones of the object are clearly expressed, which is more conducive to the expression of the object's sense of volume and texture, and helps to reflect the sense of space and hierarchy of the picture. Objects with special shapes and materials will not produce clear changes in three major surfaces and five tones after being affected by light, such as: liquid, glass, metal, etc.

Tone is an overarching tendency of the picture. High-key, gray-toned, low-key colors are a kind of hue. Warm, cool.

Highlights are highlights, which are really slow and difficult to explain. It's roughly the brightest point on an object.

As the name suggests, projection is a shadow cast by light.

Specular, light, gray, light and dark junction, gray, dark, projection.
