Self taught sketching, why doesn t there be that three dimensionality is the problem of where 100

The so-called three-dimensional sense is a three-dimensional figure, and our paper is a two-dimensional plane, if you want a strong sense of three-dimensionality, then first of all, you must make sure that your perspective is correct, because the perspective is correct It will not look weird, followed by the chiaroscuro, the black place is black, the bright place makes him light up, and the contradiction between black, white and gray makes him contrast stronger, so that there will be a strong sense of three-dimensionality, you can try.

In your picture, the direction of the light source is chaotic, and there are some problems in perspective, the most important thing is that the chiaroscuro is not opened.

If you want to have a three-dimensional effect, you need to strengthen the contrast of the highlights and shadows, and the accentuated shadows will also make them appear more three-dimensional. Self-study is already very powerful, but painting is not a day or two can be learned, if you like it more often copy some paintings, see some about teaching painting **, painting skills will slowly improve.

<> "You draw much better than mine, you're going to give up, what do I have to do!"

I've also learned.,This really needs a professional person to see at a glance that it's a ** problem.,Sometimes it's the shadow treatment is wrong.,Sometimes it's maybe other paintings are not very accurate.,You can give a professional art teacher or friend to show you the problem and demonstrate it to you.,You'll be clearer.。 That's the difference between a professional and a non-professional. Come on.

Self-study also have to read it on the Internet or buy a book, it is difficult to explore it yourself, your painting does not have a three-dimensional sense, because the blackness of the shadow is not enough, deepen the shadow part and take a look.

The problem of light and shadow and structure, light and shadow change according to the form of the structure, first solve the problem of structural perspective!

You can actually draw this well, you have to learn more about how to conceive this piece.

The three-dimensional sense of sketching is a three-dimensional perception composed of three different gray combinations of light, gray and black through the relationship between light and shadow. For example, if you draw an apple with a bright area in the upper left corner, the light source is in the upper left corner. If there is an angle at which the light enters, the corresponding shadow area, i.e., light and dark, can be determined.

Shaded areas are indicated by the maximum grayscale in the frame, and the darker the drawing, the stronger the chiaroscuro. However, if it is only a chiaroscuro, it can not effectively reflect the three-dimensional structure of the object, and there needs to be a gray transition area in the middle, that is, darker than the light part, and lighter than the dark part, so that the whole object gradually darkens from light to dark, and then the three-dimensional feeling comes out.

For basic sketching, I first learned to draw simple shapes such as cubes and spheres. In addition to grasping the structure and shape of an object, another purpose is to break down the light and dark relationships of an object. To learn how to draw a three-dimensional feeling, first of all, you need to exercise the black and white filtering skills in your mind, and observe things decomposing from the world of color to the world of black and white, forming a monotonous unity of black and white.

Before painting, observe the object to be drawn, determine the outline, and then divide the object into multiple light and dark areas, the light part is white, the dark part is the bottom, and the middle part is gray.

Of course, in addition to chiaroscuro, you also need perspective structure analysis, that is, to draw a large picture close to yourself and a small picture far away from yourself. It is a way for the human eye to see the world, and it can also show a strong sense of three-dimensionality in the painting. For example, if you draw the near part of the object according to the normal scale, draw the far part according to the longer scale, and finally tilt the whole picture to a certain angle, you will find that the picture on the plane seems to be on paper, which is also the application of the principle of perspective.

In fact, there are many problems that need to be solved in sketching, such as the sense of volume, spatial hierarchy, texture, structure, emotion, etc. The three-dimensional professional degree should be called a sense of volume, which is only the most basic problem that needs to be solved when learning to sketch. You can draw a single object or a combination of objects.

We must pay attention to the tone of perspective, that is, the contrast between real near and far objects and near objects, to weaken the contrast of distant objects, not only to consider the volume of a single object, but also to consider the integrity of the picture, to give the correct expression to the position of each object, the volume of the image is not only a good spatial position.

You can paint the three-dimensional effect by applying eyeshadow, which is probably the best, and only after the shadow is painted will the overall three-dimensional effect be revealed.

You can choose to use some light and shade to express the three-dimensional feeling, and the outline line drawn at the end can be said to be very good.

I think you should sketch the lines in white, so it's very beautiful.

Structure, there must not be structural errors, for example, the cube can't look like a cuboid, and the perspective relationship must be found well.

The relationship between the front and back should be correct, close to the real and far from the virtual, the background can not be painted thinner than the plaster and the interlining, and the interlining cloth cannot be thinner than the plaster, in short, the main object should be highlighted.

The light and dark sides, mainly reflected in the boundary between light and dark, to emphasize that the above is the foundation, after doing these, you can depict the details, for example, the plaster is missing a corner, can be simply depicted, so that the picture is more real and vivid, but we must pay attention to the coordination and unity of the picture, can not draw the missing corner more fine than the plaster, then it will be a failure.

The boundary between light and dark is the heaviest place in the whole painting, and the dark part cannot be heavier than the boundary between light and dark. The second is the highlight. The dark part also has a reflection, that is, the bright part of the dark part, pay attention to the bright part of the dark part must not be more than the direct light of the bright side, an object is composed of countless faces, of course, each side is different.

The brightness is also not the same. Of course, you can't draw all the same, and then the painting will look flat.

The three-dimensional sense of the sketch is expressed through the relationship between light and dark, that is, the combination of three different gray colors of light, gray and black constitutes a three-dimensional perception. The bright part is the highlight, which represents the direction of light penetration, for example, drawing an apple, there is a bright area in the upper left corner, indicating that the light source is in the upper left corner, with the angle of light penetration, you can determine the corresponding shadow area, which is light and dark.

The shaded area is represented by the largest gray scale in the frame, and the darker the painting, the stronger the contrast between light and dark. However, if there are only two pure contrasts of light and dark, which cannot effectively reflect the three-dimensional structure of the object, there needs to be a gray transition area in the middle, that is, it is darker than the light part and lighter than the dark part, so that the whole object gradually changes from light to dark, and the three-dimensional perception comes out.

There are three ways to sketch a three-dimensional effect:

1. Be good at inducting geometry: the surface of some objects is more complex, such as the front and side of the human face, the sunken eye sockets, the protruding nose in the middle, the two flat cheekbones, etc., which are more difficult to draw a three-dimensional sense, but if these are all summarized into geometric shapes with clear faces, it is not so difficult to express.

2. Make good use of light and shade to express three-dimensionality: objects are composed of a variety of different faces, and under the illumination of light, different faces will leave different degrees of depth. When observing an object, the volume of the object is taken into account first, then the surface of the object, and finally the line of the object.

That is, it is necessary to follow the order from the whole to the parts, and the parts should be expressed based on the whole. After using dots and lines to shape the surface, the light and dark tones are drawn by contrasting the depth and shallowness.

3. Use the combination of light and shade and contour lines to highlight the three-dimensional sense: the contour line refers to the structural line, which is mainly based on the structural line, supplemented by light and shade or supplemented by light and shade, supplemented by the structural line, and shows the three-dimensional sense with the changing structural line, and draws the three-dimensional object with the thickness, lightness, weight, virtual and real lines.

In short, it is necessary to master the rules in order to draw a good sketch work, to observe and compare from the whole, and to express based on the structure to be able to grasp the structure and proportion of the object.

Deep, deep is first built on a large black, white and gray relationship, what is the painting, that is, what you call three-dimensionality, what you paint is actually space, the spatial relationship between objects, you go to see some of the master's paintings, such as Menzel's, you go to search, he does not paint many details, but the black, white and gray performance of space is in place, I think the problem you have to solve now is to lay a good foundation for sketching, if you draw for the test, pay attention to the transition between them not too soft, That is, the span can be larger than what you see with your eyes, this can refer to those college entrance examination sketches for the exam, the most understandable, you put a group of still life and see it in the book, shoot it in black and white with your mobile phone and then compare it with the picture you see, and then we are painting, it is performing, not like shooting ** How it is, to add your own subjective consciousness and feelings, and in some places your span is widened, his sense of light is easy to come out, This can be referred to in Nizhny Menzel or Rembrandt (who has a good light and shadow). Also, don't be in a hurry to paint gouache, when the time comes, you should also pay attention to the span problem, which is a mistake that many people are prone to make. What grade are you in?

This is just a stage of learning, I don't know if your teacher has told you, there will be some stages in the process of painting will be very broken and painful, (I am like this, suddenly feel that I can't draw, especially tormented) at this time you might as well listen to the pen, sort out the ideas of painting, or take a walk to see what others have drawn,; Not deep enough, it means that you need to enter the stage of careful observation, you are not bad at drawing, but your requirements for yourself are slowly improving, the so-called eye is high; Be patient, you don't need to draw too much, as long as your mind moves and thinks more, I believe you can.

The lack of three-dimensional sense is because of the relationship between light and dark, the solution to this is to learn to transition, to distinguish between light and dark, to find the law of change, the color of the dark and the light to have a contrast, but first of all, the line drawing should be good, the perspective relationship should be found right, not deep enough refers to only in the copying of the cat and the tiger, lack of their own understanding, so when they paint always badly, you have to learn to understand the use of each piece of color, but also learn skills, this is the need for more practice, more experience, everyone is like this, I painted a plaster body for a month, take your time, believe in yourself, what can't be asked of me.

The lack of three-dimensional sense is mainly that there is no three-dimensional concept in the brain, for beginners should cultivate a three-dimensional sense, to show the real appearance of the object through observation and imagination, any object has three sides, as long as the three sides are shown to have a sense of volume, and then give details, such as adding light and dark, the three sides are subdivided into multiple faces, adding reflections, highlights, etc., the painting is not finished, the deeper the painting, the better the effect.

Three-dimensional sense is not difficult, the main thing is that you must distinguish the relationship between light and dark, that is the dark side, that is the bright side, and the middle tone, the dark tone is aggravated, the bright side is slightly brought down, the middle tone is too good, and the point is that the three elements are not too much, look at it from a distance for a while, don't make it too dark or too light, I hope the landlord is satisfied with my answer.

To find the shadow area first, the boundary between light and dark, then accentuate the dark part and apply a little less on the light part.

You first analyze a few elements that make up a three-dimensional: 1The spatial shape of the object (i.e. its own structure)2Clarity and blurring of visual acuity.

3.The difference in the contrast between the near and far gray scales.

You can start with simple geometric modeling props and gradually increase the difficulty to train the spatial modeling.

First, draw three-dimensional objects with lines, practice repeatedly, train your observation skills, and gradually try to play light and dark tones.

Nowadays, it is very common to have ordinary, many newcomers can't feel the freshness, and the flat and rigid ** can't meet people's desires.

After PS, although he satisfies the vanity of beauty, his effect of using blurring and whitening to disguise still can't change the tradition.

Recently, a three-dimensional ** is very popular in developed cities, he can do human movement, **with the movement, reflecting the flexibility and vitality of **.

**The distance between objects can also reflect the hierarchy.

It really gave her a vivid and real effect.

Three-dimensional concept.

It is necessary to have a three-dimensional image of three-dimensional space. Therefore, the study of sketching should establish a three-dimensional concept in the mind from the very beginning. In sketching, a body is made up of many perspective planes of different orientations and shapes, and the faces form a three-dimensional shape.

With this concept, we can grasp the basic point of three-dimensional objects in various images. Brain, Eye, and Hand Collaboration In order to successfully master the basic knowledge and expressive skills of sketching, it is necessary to pay great attention to the combination of brain, eye and hand in training. Painting requires not only the eyes and hands, but also the brain.

Only by combining rational analysis with perceptual expression can we better understand and master the basic essentials and expressive skills of sketching. In the training of painting, it is necessary to summarize and analyze the observed images, and to generalize the relationship between the structure of the form, which is impossible not to think about seriously. A person who is good at thinking is also a person who is good at learning.

With a correct understanding, we can more effectively direct the training of eyes and hands. Therefore, diligent thinking and paying attention to the unity and cooperation of brain, eyes and hands are the necessary subjective conditions for drawing a good sketch.

Secondly, before painting, we should observe and study the basic shape of the object, see its light direction, structural modeling, and three-dimensional effect, and then outline its general outline with straight lines, and then determine the three major parts of the object according to the light source. A uniform line is laid on the deep surface and the gray surface first, so that the light-receiving surface is temporarily vacated, so that the object is represented by a large surface, and then the details of each block surface are also divided into small pieces and small surfaces according to the light, side light, and shading. The reflective part should be left in the deep side, and the highlight part should be vacated in the light side to make it have five tones.

It is also necessary to pay attention to the light and shade of small pieces and small facets, so that they obey the uniform tone of the large surface, which in turn must be subordinated to the whole. Finally, layers of cohesion are added between these faces, so that it is natural and rounded, until it expresses its texture. After the sketch is completed, the depicted object should be coordinated and perfected.
