How to draw light and shade in a sketch? How do you draw light and shade in a sketch? What about the

Observe carefully, after drawing a part each time, you should observe whether the overall light and shade are reasonable, in addition, it is best to draw the darkest part first, then draw the darker place, and finally draw the shallow place, in an orderly manner.

Shake your hand in the right eye and left eye respectively.

There will be bright relationships.

The closer and deeper you are to the object, the farther away you are, the more you want to be empty.

Mention that don't blur with your eraser fingers.

Affects image quality.

Points will be deducted for lack of clarity during the exam.

Don't portray it.

It should be handled well with gradient relationships.

Remember to get closer to the object and get deeper.

Always go deep around the boundary between light and dark, and it is easy to appear clearly structured.

Things that are close to the line of sight have a strong contrast, and those that are far away will appear to be more empty. If you draw them all in contrast, it will appear that the whole picture has no focus.

After composing, first spread out the tones, and then gradually deepen around the boundary line and outline of light and dark, pay attention to the whole piece, the whole picture goes deep together, otherwise it will look disjointed.

Start at the light-dark boundary and gradually become lighter. Draw the dark part first, then the gray part, and then the light part. If it's a still life, you should also pay attention to the highlights. In short, practice more, buy a book and observe it carefully, and imitate it. Copy first, then sketch. (That's how I was when I was learning).

Find out the boundary between light and dark, lay out the big tone, go dark and bright, and practice more slowly.

First, the darkness of the background color is roughly laid out with a thick pen, then blurred with paper or directly with your hands (it is best to wipe until you can't see the lines), then use an eraser to erase the highlights, and then start to draw details with a thin and hard pen. Find the feeling and practice a few more times and it will be much better.

If you feel difficult, you can first use the technique of big light and dark, and then go deeper, and there are "three points of light and seven points of repair", if you can paint an apple for three days!

Draw the dark and light parts first, then wipe the gray surface with paper, and then line up the lines again.

Preparation tools: drawing pencil, sketch paper, pencil sharpener, eraser.

Let's take a square as an example:

1. The first step of square painting is to shape the shape and structure.

2. Then draw the dark side, that is, the black side, and make it so large that it is a good projection.

3. Then, reflect the gray surface and background.

4. Finally, I will depict it in depth, talking about black, white, gray, projection, background and other bright and dark relationships.

5. [White]: The side closest to the light, [Gray]: The side that is second only to the white side from the light, [Black]: The side that does not illuminate the light, projection: the shadow pin produced after projecting the light object.

The solution is to first brighten the brightest part of the picture as much as possible, and maintain the appropriate brightness of the bright and gray parts, and then deepen the darkest part of the picture as much as possible, and then the second dark, the second dark......, the second dark(These are generally near the boundary between light and dark), and the reflective parts should be neither too bright (deeper than the gray parts) nor too dark. If it's too bright, the picture will be messed up and it will be spent. If it is too dark, the dark part will be opaque, breathable, compact, greasy, and have no sense of space.

Sometimes the chiaroscuro is pulled apart, but not according to the three major parts of light, dark and gray, the bright part appears dark color that should not be, and the dark part appears that should not have bright spots. In this case, the picture is loud, but it is very messy and flowery. Often, some students with a slightly better level mistakenly think that if they draw solidly, they will inevitably "flower".

This is a wrong perception. In fact, no matter how it is shaped, it can't go beyond its own light, dark, and gray characters in light and shade. Some students deliberately draw the highlights very deep in order to make the highlights stand out.

It is also a manifestation of a lack of holistic awareness. Just imagine, the brightest place in the outside world can be dazzling, and the brightness of white paper is simply not attainable. The darkest places are also not within the reach of pencils and charcoal.

We can only express light and dark in a certain proportion. When drawing the bright parts, take into account the depth that can be achieved in the dark parts. When drawing dark parts, you should also take into account the brightness of the bright parts.

If the contrast between virtual and real is weak, it is difficult to open up the spatial relationship, the primary and secondary relationship, and the quality of expression. Generally speaking, the main real and the secondary virtual, the near real and the far virtual, the square and the round and the virtual, the hard and the soft and the virtual. If we blindly make the ground solid or blindly empty, the spatial relationship and texture will be unclear.

In addition, blindly making the image stiff; Blindly pursuing the effect of relaxation and being empty everywhere is easy to make the picture empty and empty. Sometimes the boundaries of the void are not clear, but the "void" is not vague or ambiguous. The method of expression of the great void can only be understood, not spoken.

There are many things in art that cannot be spoken, and everyone should look at fan paintings more and experience them with their hearts. When some students mention emptiness, they think they want to brighten it; When I mentioned the truth, I thought I wanted to draw darkness. In fact, the bright places can also be painted realistically, and the dark places can also be painted virtually.

Reality and light and shade are different concepts. Generally speaking, the virtual and the real are in terms of the turning line. From the point of view, it is a matter of the clarity of the turning line, and the question of whether it is eye-catching.

Whereas, light and shade are expressed in painting as the shade of color. Of course, there are depths and shades of turning lines, but they are not virtual and real. "Accurate structure" is always the basic requirement of the picture.

Although it is popular to divide sketches into structural sketches and tone sketches, this statement is not scientific, it is just a customary name, not a professional method of division. Because structure is also a key thing in tone sketching. For an object, the light and shade will change with the change of light, but the structure will not change with the light.

Therefore, light and shade are only the means of expression, and the structure is the key. Without light and shade, it may be difficult to express the atmosphere and effect of the picture, but without structure, there is nothing.

The methods of quickly and accurately mastering the light and dark tones of sketching are summarized as follows:

1. Suggestions before learning to sketch the relationship between light and dark.

1. Scientific and advanced sketching tutorials. There are a lot of tutorials on the Internet, and the level is uneven, so having a good tutorial will make you less detours.

2. Learn step by step from simple to complex, from shallow to deep. Starting with a sphere - a cube - a polyhedron - a still life - a plaster statue - a head - a bust - a human body - a landscape.

3. Analyze the light and shadow changes from the internal structure and physical structure of the object in order to draw accurate light and shadow changes. Maybe you think this sentence is not easy to understand, to put it simply: for example, if you draw a sketch head, you must master the bone structure, muscle structure, and block analysis of the head, so that you can analyze the light and shadow, not just the appearance.

4. After mastering the theory, practice more and analyze the light and shadow changes of different objects. When you are engaged, you will look at everything and involuntarily analyze the changes in light and shadow. I believe that many students have had such an experience.

Second, the three key knowledge of light and dark tones.

1. Sketch three sides. Black, gray, white.

2. Five tones of light and dark.

3. Light and dark handover line.

4. The solution to the gray picture.

Excessive should be even, the boundary between light and dark, the color is the heaviest, followed by the dark, then the reflection of the dark, and finally the highlight and highlight. The contrast between black, white and gray should be stronger, so that it is louder.

Recognize light and shade in sketches.

1.What is light and dark: (let students freely associate and play to evoke old experiences).

2.The reason for the occurrence of light and shade: light and shade will be irradiated by light sources (whether natural light sources or artificial light sources); Without light, our eyes will not see anything.

3.The basic rules of light and shade:

1).The bright part is the direct (directional) part of the light source.

2).The place where the light source does not shine (backlight) is the dark part.

3).The reflected light forms a gray part in the middle.

4.Ways to use a pencil to express light and shade:

1).When the pencil is drawn upright with the tip, the line is clearer and firmer; When the pencil is drawn diagonally on the abdomen of the tip, the lines touched by the pen are blurry and weak.

2).The direction of the strokes should be organized so that they do not become confused.

5.Pencil drawing using the eraser precautions:

1).When I was a beginner, I always felt that I was not satisfied with a stroke, so I immediately erased it with an eraser, and when I didn't draw it right the second time, I erased it again, which is the worst habit. One is easy to hurt the drawing paper and leave a scar on the paper, and the more you draw, the more uncertain it becomes, so you should try to avoid it.

2).When the first stroke is wrong, you can draw the second stroke, so there is a standard when drawing, easy to correct, and after everything is drawn, then the pencil line where it is not used, gently erased with an eraser, so that the whole picture is much clearer and more lovely.

3).In fact, many useless line marks on the picture are usually covered by the dark part in the end, and we only need to erase the exposed part, which is also more labor-saving. At the same time, the unused line marks often invisibly become the foil of the subject, so not only do they not erase the harmless picture, but sometimes they receive an invisible effect, which is what we must pay attention to.

6.Picture guest and host performance:

1).Front, nearer, should be strong and clear; Behind, farther away, should be shown to be weak and indistinct.

2).The subject should be clearly and conspicuously, and the subordinate object should be aimed at foiling the subject.

Preparation tools: drawing pencil, sketch paper, pencil sharpener, eraser.

Let's take a square as an example:

1. The first step of square painting is to shape the shape and structure.

2. Then draw the dark side, that is, the black side, and make it so large that it is a good projection.

3. Then, reflect the gray surface and background.

4. Finally, it is deeply depicted, black, white, gray, projection, background and other light and dark relationships.

5. [White]: The side closest to the light, [Gray]: second only to the white side from the light, [Black]: The side that does not illuminate the light, projection: the shadow generated after the light object is projected.

Draw a lot of a more three-dimensional picture in your mind, you had better have a physical object to observe the painting, or buy a sketchbook to copy (buy the kind of big book, it is best to find the kind of A4 paper as big as a book), the relationship between light and dark is based on the projection of the real thing, shadow, reflection, dark side, gray surface, bright surface, bright surface and other transitions Here I can't explain**The painting is dark**The painting is gray**The painting is bright, but it can tell you that the light side of the object must be the bright side of the highlight Then according to the light intensity The shape angle of the object Observe to distinguish the light and dark sides, The lines are generally required to be straight and uniform in thickness There can be no hooks with dotted strokes, and the lines are generally crossed and overlapped to draw such as the darker surfaces Repeatedly draw crossed lines on it Draw in groups The more overlapping the multi-line group, the darker the group, and then according to the brightness and darkness of the surface to be drawn, master the thickness of the nib Such as the bright spots The lines should be thin, and the charcoal nib is best cut into a square You can constantly flip 4 corners to draw This is easy to control the nib You don't need to sharpen the nib often, and you don't have to draw too carefully when you make the outline Roughly draw the outline You can know the general outline of the object in your heart, otherwise the drawing is too detailed, which will make the picture behind it feel dirty, or even only use a few points to determine the proportion of the object, and even if it is more powerful, it will be drawn directly.

I also studied sketching for a while, and my understanding of sketching light and shade is that the so-called light is the bright side of the object, and the so-called dark is the dark side. When arranging the lines, start from the darkest part of the dark side, and then gradually transition to the light side, while paying attention to the color and texture of different objects, and grasp the weight of the lines. In addition, when arranging a row of lines, the distance between each line of the row should be the same, and the size of the lines should be the same, just like the queue in the military parade.

And then there is, it seems that the angle of the two rows of lines that intersect should be about 45 degrees...

You can look at the book and copy it first, and you will have an understanding if you draw more by yourself. If you are a beginner, it is better to copy it first and then sketch with the same plaster cast.

Or you have to paint more, still life is generally the deepest shadow root, and then the light and dark boundary line and reflection, of course, it also depends on the texture and color of the object itself, the scene sketch generally wants to depict the deepest scene, to focus on depiction, but it does not mean that it is the darkest color, but the contrast is strong, and the general sketch does not first draw a very accurate line drawing and then on the light and shade, are all looking for the shape almost on the light and dark, do not let the outline line obvious. Hope it helps.

This one is very simple, you said that the light source is set, first look at the object and find the boundary between light and dark, the boundary between light and dark is the darkest, and then draw it on both sides so that the object can turn around.

Gestalt allows you to squint your eyes and distinguish between light and dark greys based on what you see, while also paying attention to the color and texture of different objects.
