Black and White Illustration of Children's Stories —— How to draw and read illustrations

Who remembers Grimm's fairy tales and Andersen's fairy tales when I was a child? They are black and white illustrations. There are four illustrations on a page, and there is a story under each illustration.

UPS power supply

I really hope the following answers can help you.

1. Is UPS useful in the case of instantaneous low voltage? It seems that UPS also has a voltage range of 165V-how much V? What other conversion times are there? Can it be accurately judged and converted when the voltage is low (without power failure)?

Answer: If you bring a computer with UPS, you can use it. Generally, a computer can calculate about 300W W W. Generally, the voltage stabilization accuracy of UPS backup belt is (162~268)VAC. If the voltage is too low, you can switch to UPS for power supply. If the mains electricity is normal, it will be output to the computer through UPS.

2. Some people say that the MT500 of Sander has the function of stabilizing voltage. What are the specific parameters related to voltage stabilization? Is this power supply useful for my situation? What about GT500? Does it work?

Answer: Suntech is really no problem with this model, but the price is more than 400. Don't use it if it's not GT or TG500 without voltage regulator. Just buy K500, just 220-230. It also reported the manufacturers of voltage regulators for three years.

3. I saw on the Internet that Hangjia's wide power supply can stabilize the voltage. How stable can it be? Who has used it, or someone in my situation, what do you use?

A: The wide power supply should be

Regulator

All right! Generally, voltage regulators with AC220V accuracy of 3%-5% (1% roughly calculated as 22V) are less than several kilowatts, and some of them have accuracy of 1% but the price is outrageous! I tell you, the accuracy is 3%-5%, and the price is similar to UPS, but UPS has more functions than power failure. It is best to use UPS.

4. The voltage here is low, but how many pictures are so low? I only have one in my hand.

multimeter

, or analog, not electronic.

A: The pointer multimeter test is not accurate. Generally, the digital multimeter in the market is inaccurate, and the voltage obtained by multiplying the square root value by 1.4 is inaccurate.

The problem that electric lights will flash.

Generally speaking, there are too many electrical equipment around or at home. For example, the commercial electricity we use is just like water flowing from a small stream to a reservoir. But there are many large discharge points in the reservoir, and the water in the stream can't flow so fast, which leads to the result that commercial electricity is also flowing. If you don't believe that you can turn on the electric light, when you turn on the air conditioner, it will dim and recover. This shows that the commercial power is instantly sucked away and sucked to other equipment. This should only happen in summer.

How to draw black and white decorative illustrations Illustrations (paintings) are images expressed by patterns. In line with the principle of unity of beauty and practicality, lines and shapes should be as clear and lively as possible for easy production. Illustration is a universal language in the world, and its design is usually divided into characters, animals and commodity images in commercial applications.

Commodity image

Product image is the expansion of animal personification in the field of goods, and anthropomorphic goods give people a sense of intimacy. Personalized modeling has a refreshing feeling, thus deepening people's direct impression of goods.

classify

As far as the idea of commodity personification is concerned, it can be roughly divided into two categories:

The first category is complete personification, that is, exaggerating goods and using the characteristics and modeling structure of goods to personify performance.

The second category is semi-anthropomorphism, that is, adding hands, feet and heads unrelated to commodities as anthropomorphic characteristic elements.

The above two anthropomorphic molding technologies make the goods humanized and personalized. Through the form of animation, emphasizing the characteristics of goods, its actions and words are directly related to goods, and the publicity effect is more obvious.

Illustrators often draw illustrations for graphic designers or directly for magazines, newspapers and other media. They are generally professional illustrators or freelance artists, and have their own themes and painting styles like photographers. Their professional sensitivity and desire for new forms and tools have led many of them to use cg animation design tools to create illustrations. The software function of Cg animation makes their creative talent play a greater role. Whether it is simple or complex, whether it is traditional media effects, such as oil painting, watercolor, printmaking style or the endless new changes and new interests of digital graphics, it can be completed more conveniently and quickly. Digital photography is the latest development of photography. Photographers shoot objects with digital cameras or scan traditional positive films into computers through scanners, then adjust, combine and create new visual images on computer screens, and finally output positive films or negative films through film recorders. This brand-new photography technology has completely changed the creative concept of photographic optical imaging, taking digital graphics processing as the core, and is also called "darkroom photography". It blurs the boundaries between photographers, illustrators and graphic designers. Nowadays, as long as they are talented, they can complete all three tasks on the same computer.

How to draw a reading illustration can be selected and designed according to your creative style and the theme of the story. Here are some reference steps:

Preparation materials: pencil, watercolor pen or colored pencil.

1. Determine the theme of the story: First, determine the theme of the illustration and the way of picture expression according to the content of the story to be created.

2. Character design: Design characters according to the story, and draw sketches or outlines.

3. Layout design: consider the layout and overall effect of the illustration, and design the layout of the characters or scenes.

4. Color filling: Color the picture according to the conveyed emotion and theme. You can use watercolors, oil paintings, pencils or digital software.

5. Add details: Add details and small objects to the picture to increase the richness and depth of the picture.

6. Finish: Make the final adjustment to the illustration, check the details, and finish the illustration after determining the final effect.

The origin of reading illustrations:

Reading illustrations refers to pictures added to books to help express the meaning of the text or tell the story of the text. The appearance of illustration by reading pictures can be traced back to ancient times, and the earliest illustration form is hand-drawing. For example, there are combinations of words and patterns in the Oracle Bone Inscriptions in the ancient Yin Ruins. With the development of printing, illustrations become more and more popular and become an indispensable part of modern books.

Reading illustrations plays a very important role, which can help readers better understand the text and enhance the reading experience. In children's literature, illustrations play a very important role in helping children better understand stories and stimulate their imagination.

With the continuous development of illustration technology, modern reading illustration has become more and more exquisite and diversified. Now, reading illustrations has become a very attractive part of the publishing market.
