How to determine the direction of the projection in the sketch, how to understand the projection in

Of course, the direction of the projection is the same as the direction of the light.

Determine the direction of the projection to see the object directly.

Or find the light **, when there are many lights, it is best to choose only one light to paint.

The size is determined by the angle of the rays, and the smaller the angle of the rays, the larger the projection.

The angle of the turning surface that causes the projection is related to the blackness of the projection.

The larger the angle of the turning surface, the heavier the projection color.

If you are indoors, because of the fluorescent lamp, there are often several light sources, you can choose the most obvious light source to paint, the direction of the projection and the light source is the same, the light source is about low, the projection is about long, and the closer to the object, the darker the projection.

The projection of an object is not dead, it is alive. Its existence allows objects to fall better in a certain space. It doesn't look like it makes the object feel like it's floating.

The size of the projection depends on the level of the light source you are taking and the distance from the object. The high or far projection area of the light source is relatively small. To the top of the object, the projection is minimal.

Otherwise, it's the other way around.

Look at the direction of the light.

How to draw a sketch test-: If you practice with lighting, you will see it clearly, and if it is natural light, choose the main light.

There's a lot of practice, and you don't have to think too much about light when you wait for the exam, because your hands will reflect it faster than your brain.

Just put it under the sun and take a closer look.

To see the light shoot out from the **, the opposite side is the projection!

The understanding of projection in sketching is as follows:

1. Projection can be understood as the dark side of a background object. The closer you get to the projected object, the deeper it gets, and the farther it goes.

2. The shape of the projection under strong light is the shape of the projection object, and the outline of the wheel carrying the rock is relatively clear, and the difference between the shades is relatively small, which is very easy to depict; Multiple projections will be produced under natural light, because the light source is in different directions, and the projection will also start to spread in different directions from the junction of the projected object and the background, and the more overlapping, the deeper the depth.

3. The projection is not all black, but the content of the background should be shown, including the shape, color, and texture of the smooth and rough. The edge of the projection should be clearly represented, depending on the direction of the light source and the shape of the object. The place close to the object is clear and slowly blurred.

Projection is more used to set off the edges and spatial order of objects. At the same time, the projection with changes can enrich the picture, if the projection is the same, the overall picture is very dull and lifeless.

Projection is the image formed by light projection objects, the shape of the projection is related to the shape of the object itself and the angle formed between the light and the object, and the depth of the projection chromaticity is directly related to the intensity of the light.

The sketch factor of the object.

1. Highlights. 2. Intermediate color.

3. The boundary between light and dark.

4. Reflective. 5. Projection.

Highlights and mid-colors belong to the highlights.

The boundary between light and dark, reflection, and projection belong to the dark part, and the reflection is generally darker than the intermediate color.

Objects that are soft, rough in texture, and not strong in their own refraction, the contrast between the five tones is relatively flat. The contrast between the five tones of objects such as glass and shiny metal is more obvious, and the reflection is also large.

First of all, from the physical aspect, the projection in the sketch is actually a shadow formed by the light source being partially blocked by the object.

In terms of sketching, in fact, projection plays more of a role in holding up the responsibility of the main depiction of the object. No matter how well an object is portrayed, it will not be real without projection. And when you draw a projection, you should pay attention to the fact that the projection also has its shape, its outline, its depth, and its relative position to the subject.

For the projection, there are also changes in the virtual and real, and the edge of the projection, if you observe carefully, will also be light and heavy, generally near the real and far virtual. It needs to be seen on a case-by-case basis. If you still don't understand, you can ask me.

1. First draw a square and divide it into four parts.

2. Draw the diagonal line of the square, and divide a section on the diagonal that is the same length as the side length of the quarter small square, and connect the parts with the same radius with an arc to draw the shape of the circle. Later, when you are proficient in drawing circles, you can skip this step.

3. Erase the unwanted auxiliary lines and gently draw a line between light and dark.

4. Start near the boundary between light and dark, and start the line with the light line at both ends and the heavy in the middle.

5. Continue to arrange the lines in this way, sweep out the bright side, dark side and gray side, and finally draw the projection after the overall adjustment.

2. Draw sketch shadows:

In the final analysis, sketching is the process of capturing the shadows of light on objects with brushstrokes on the picture, and finding the "three sides" (light, gray, and dark) and the "five tones" (highlight, light, gray, dark, and reflective).

The tone of drawing geometry and still life is relatively simple, as long as you find the boundary between light and dark, see clearly the reflection of the backlight, and distinguish it with black, white and gray.

The light is taken down. The part of the object that blocks the light is projected into a projection. The part of the projection that connects to the object is solid. Slowly becoming weaker. It can be ground by hand after the soft lead cable is arranged.

The light is projected from that side to that direction, and in one direction, the shadows are deeper than the shadows, the shadows are deep in the near area, and the shadows in the distance are lighter. The edge of the box that has a shadow is heavy and then lightened, and if it is excessive, it is gone.

The place close to the subject is deep and slowly becomes shallow, and it is actually very simple to draw the past

Start by observing the direction of the light source.

The direction of the light source is easy to understand, that is, the direction from which the light is coming from. Shadows appear in the opposite direction of the light.

The second is the softness and hardness of the light quality.

Hard direct light creates shadows with clear edges, and soft scattered light creates shadows with blurred edges.

As a sketch exercise, a combination of soft and hard light is generally used, and the projection edge is clearer near the bottom of the still life, while at a distance from the still life, the projection edge is deliberately blurred in order to express a sense of space.

The color of the projection is also the closer to the bottom of the still life, the heavier, the farther away from the still life, the greater the influence of ambient light, and the lighter the projection.

The closer the projection is to the object, the more solid it is (the drawing is heavier), and then it slowly changes from deep to shallow, and the lines can be relaxed at will. The lines should not be painted, and the intersection of the two lines should not be perpendicular as much as possible. The most important thing is to be patient and draw patiently one at a time.

It should also be noted that the first time the line is arranged, try to be as thin as possible.

The projection is also reflective. The projection of an object is actually a gradient. From the deepest at the root of the object, to the shallowest at the end of the projection.

The junction of the projection and the object is where the color of the entire projection is heaviest, decreasing from the root of the projection to the end. This is also the meaning of the edge line of the projection, which is gradually shallower. In fact, you can do this, when you draw the projection, the shape of the projection, after the gradient is drawn.

Card one card at the root of the projection will do. If you don't understand, you can continue to ask!

Put the real thing in a closer look, and you'll find the trick.

The closest place to the object, the line drawing is a little more solid (that is, heavier), the farther away the more imaginary, pay attention to compare the relationship between the projection and the sketch of the object itself (that is, heavier or lighter than the color of the object) to compare the depth, the edge line processing is cleaner.

Have you ever painted plaster geometry? Think about how it was painted at the time. Painting is the same for others, that is, the type is different, the principle is the same, draw a few more times to understand, now tell you that you can't draw, your own action and your own summary.

Whichever direction the light is coming, the projection is below the other side.

The more concentrated the light source, the more obvious the shape of the projection, the more parallel the light source is to the object, the longer the shape of the projection, if it is a fruit or a jar, the more parallel the light source, the more elliptical the projection.

The shape of the projection must be based on the object being drawn, but the shape of the projection is not strictly required to be exactly the same, the main thing is to grasp the relationship between light and dark.

The shape of the projection is also related to the change of the shape of the object projected, and if the projection is on the interlining, the undulating change of the interlining will also bring changes to the shape of the projection.

The closer to the object, the darker the color of the projection part, and the object close to the projection has reflection, can not blindly turn into a dark color, pay attention to the change of light and shade, transition.

The projection belongs to the place where the light cannot be illuminated, and the lines should not be obvious, and even the lines at the projection can be blurred.

The closer to the object, the more solid the projection (the painting is heavier), and slowly from deep to shallow, as for the line, it is just arbitrary, and it is easy to do it.

The projection is a part of every object, and when drawing, pay attention to the heaviest place where the object is close to the ground or tabletop, so that the object looks like it falls on the ground, and then it transitions outward in turn according to the shape of the object.

Hope it helps

In fact, you don't understand it if you say too much, so first draw according to the book, and then summarize it yourself.

1. Use a diagonal line to mark the range 2. Observe carefully The shadow of ceramics has a sense of space There is also reflection in the projection The glass is a projection that can be seen clearly Secondly, observe the bearing surface of the projection This also has an impact 3. Don't draw dead when you start painting Don't slowly row layer by layer Don't always be a direction So that you have a sense of space 4. Pay attention to the connection between the projection and the still life There are subtle changes Light and dark are staggered The brightest is next to the darkest There is a contrast before there is a change That's it Sketching still needs more practice That's it! The lines should be clean and neat, the picture should be clean, and it will help you in the future, and you will feel it if you practice more, and you will feel it from the eye to the brain to the hand In short, observation and comparison are the most important This is the process of thinking This method is making rapid progress I promise! You have to do your best, I wish you success!!

Give it to me, please! Thank you!

Projections are a part of every object.

Pay attention when drawing.

The heaviest when an object is near the ground or tabletop.

This makes it appear that the object has fallen to the ground.

Then follow the shape of the object and transition outwards in turn.

Line knowledge is a means.

Lines drawn along the structure are always the most comfortable.

Hope it helps

This projection can be expressed in many ways, if you want to use obvious, concise lines to express it, then the lines should not cross at an angle of 90°. It should also be noted that when the first time the wire is arranged, try to be as thin as possible, for sure. Make your picture look more normal.

In addition, we must pay attention to the overall effect of the picture, and the angle of incidence of light should be consistent.
