How to draw a plaster sphere backlit with a chiaroscuro sketch?

With a pencil?? Wrong! You can draw a plaster without a pencil, charcoal and charcoal strips can just master the five elements mentioned on the first floor Say it can be understood The key is to have this most basic common sense in mind when you paint by yourself Don't always stare at the object to draw, so that you will fall into a part, and you can't draw a full picture You have to draw the general picture first Squint your eyes and divide the object into black, white and gray, which one is the blackest and which one is the brightest From simple to in-depth depiction

The gypsum sphere backlight law is important, but don't rely on the law, the place where the reverse light and dark junction is not very obvious, the opposite backlight surface looks gray, right, so this is the use of five elements, you can separate black, white and gray by this way, which is the blackest and whitest, and the two whitest things can also be separated which white, for example, the first white is in the front, the second white is in the back, then the first one is relative to the second is white, because it is real

Actually, no matter what you paint. The five elements cannot be lost.

Glossy finish. Gray side. Light and dark junction line. The dark side. Projection.

Backlighting is really hard to draw. My experience: the biggest difference between backlight and forward light is that the backlight is directly behind the bright side is the boundary between light and dark, and the gray side is sandwiched in the middle. So you have to be a little more observant.

Also, when painting, be sure to keep in mind that the inherent color of the plaster is white. Its darkest place is always the line between light and dark.

The three major sides and five major tones can not be ignored, the lower part of the ball should be the dark part, the lower part should be slightly brighter because of the desktop reflection, and the upper part is the bright part, between the light and dark is the gray part, you can take a proper look at the book, look at other people's paintings, so it will be improved!

Alas, this question is a real headache! It's hard to draw a big backlit ball, upstairs, you're not good at it! Don't be misleading, it can be said that there are only a handful of artists who can really draw the sphere well!

I can't say that I can draw the sphere very well, but I insist on it every day, especially the backlit sphere you mentioned, and you must use your heart to "pick" the direction of the sensory type. In short, even if I say a little, it is not as good as you to explore it a little bit by yourself, don't think it's boring, stick to it, and when you can solve the current problem, your sketch will really be a qualitative leap!

I'm not used to taking pictures, I'm sorry.

I wish you all the best in getting it done. Don't think that a ball is really so easy to draw, no one can really teach you, only yourself!

Upstairs, that's the backlight, huh?? Dizzy!!

The most important thing for the full backlit sphere is to pay attention to the reflection of the dark part, the boundary between light and dark should be strong, the level of the entire dark part should be rich, the most important thing is to have an arc of bright light at the top, special effect, remember to clean the eraser, and finally wipe out this trace of bright light!

The intensity of the light, the angle, the color of the background lining of the gypsum sphere, are all related to the portrayal of the dark part (because it is a backlight painting, the main part that needs to be carefully depicted is no longer the gray part), pay attention to the dark part must be transparent, even if the dark background is not reflective, you can't paint the dark part black - squint your eyes and contrast it more, there is nothing else to say @

Draw a square, then find the horizontal and vertical central axis, and use straight lines to cut out the inscribed octagon. Drawing auxiliary lines can help us shape the object of the painting.

2.Then, use a short and medium straight line to cut out the inscribed regular hexagon, and the perfect circle appears with the number of cutting angles. Don't be too troublesome to draw these steps, the right steps can better complete the painting.

3.Wipe away excess auxiliary lines to leave a perfect circle. To fully understand the three-dimensional sense, drawing requires thinking. Find the light and dark boundaries of the sphere and the projection planes, and lay them out at the same time.

4.Rich in the layers of transition gray surfaces, sketches have three major faces: black, white and gray. This is followed by a contrasting background tone.

5.Think of the sphere as a polyhedron, with each "face" having a different hue, and carefully distinguish between the dark, gray, and light surfaces. Deepen the dark part, make the transition of black, white and gray more natural, and combine with the background to draw the sphere with a sense of three-dimensionality and space.

A round sphere is complete.

Step 1: Draw a square, find the horizontal and vertical central axis, and use a straight line to cut out the inscribed octagon.

Step 2: Use a short and medium straight line to cut out the inscribed regular hexagon. As the cutting angle increases, a perfect circle appears.

Step 3: Three-dimensional understanding, find out the boundary between light and dark and lay out the projection surface at the same time.

Step 4: Enrich the transition shades of grey and create contrasting background colors.

Step 5: Think of the sphere as being composed of polyhedra, each with a different hue, and the depth is darker, grayer, lighter, and more faceted. Carefully analyze their differences and combine them with the background to make them three-dimensional.

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.

Knowledge development. Drawing a ball needs to be paid attention to.

1. Contour. When making an outline, after determining the size and position, first draw a rough square, and then cut a circle with straight lines.

2. Spread the tone. When laying out the key, first find out the location of the boundary between light and dark, paint the dark part and shadow on this part, deepen the boundary between light and dark, then draw the upper half of the light, then deepen the dark part and shadow, and then draw the bright part.

3. Detailed portrayal. When depicting in detail, the dark and semi-bright parts are deepened to enrich the tones of each level, so that they form a three-dimensional effect, so that the spherical surface is gradually rounded. To strengthen the three-dimensional effect, attention must be paid to emphasizing the most solid part of the light and dark junction line.

4. Check, adjust and modify. When checking, adjusting, and revising, the unrounded edge lines are trimmed accurately, and the light and shade that affect the three-dimensional sense of the sphere and the emphasis is inappropriately adjusted and modified, and the shadows and the darkest part of the background are deepened until they are completely rounded. The boundary between the highlight and the bright part should not be too clear, and the boundary between the reflection and the companion part should not be too clear.

To sketch how to draw a ball, you need to fix the shape and size of the ball first.

Fixed-point, type-playing, light-dark junction line, overall advancement, emphasizing the key points.

That's a great question.

Draw a square first, then cross out the four corners of the same size to form a regular octagon, and then draw it into a regular hexagon......

It gradually becomes a circle.

Then the boundary between light and dark, play the tone, and highlight the ...... light and dark

Paint in the normal order, and that's about it.

Didn't your teachers teach you?

First draw a square, draw a "ten" in it to grasp the law, there are a total of four squares to divide the circle into four parts little by little.

Don't use compass drawing like that without practice.

The circle is the most basic gypsum geometry, and you draw the line between light and dark, and then you draw the projection, and then you do it a little bit up.

It's complicated, so I won't say much about it.

The lines and shadows in the diagram are not to be drawn backwards.

Draw a square first, then cut out a circle, and draw a line of light and dark communication.

Cross, square, prism, draw circles along the edges of the prism, modify it later, rub those rubs.

Fall. ok

Draw a square first, and then repair the circle.

First draw the outline of the square with a 4b or 6b pencil, and then draw a crosshair line within the square, which is a "Tian" character, and then connect the ends of the crosshairs with two arcs to find the symmetry repeatedly. You can draw a circle. Then use the eraser to remove the guide line.

The main point of this painting method is to be accurate in the eyes, and first correct the field character painting. Finally, pay attention to highlights, reflections and shadows.

The effect of backlight mainly lies in the treatment of the light source and background, if you want to draw a full reverse imitation round light, it is not very good-looking, but if you really want to paint, the plaster backlight surface can be painted black and ready to collapse a little, the main thing is to strengthen the boundary between light and dark, the background is more difficult to do, I hope it will be useful to you.

The top light can be erased out with an eraser at a later stage. Metering can do more with the transition from gray to bright surfaces. The backlight pays attention to the front and back of the local object, after all, the light is attracted from the back, and the front belongs to the dark part.

Highlights: The point closest to the light source, which is the brightest point in the frame.

Light-receiving surface: The direct (light-oriented) part of the light source is the light-receiving surface, also known as the bright part.

Backlit surface: The place where the light source cannot be directly illuminated (backlight) is the backlit surface, also known as the dark part.

Boundary between light and dark: The boundary between the light and the dark (the location where the light and the ball are at an angle of 0 degrees).

Projection: The sphere blocks the shadows that light creates on the tabletop.

Reflective: The brighter part of the sphere formed by the reflected light from the tabletop.

Look at the position of the light source. The light-receiving surface is bright. The highlight is at the highest point on the light-receiving side. Gradual transition to ash. Then there is the line between light and dark, the heaviest, the dark part, and then leave a little reflection.

In addition, the plaster head is composed of many spheres, and the method of drawing spherical geometry will be much better.

Observe the large body first, then draw a circle. Find the boundary between light and dark, and draw the background color transition in turn. Then adjust the contrast of dark gray and bright surfaces to make it three-dimensional. You can take a look at the official website of Guojun Art, and refer to the works on the official website, which is very helpful for drawing sketches.

Determine the boundary between light and dark, starting with the dark part.

Understand the meaning of the boundary between light and dark.
