[Comprehensive History] Clothes are all over the world

The visitor didn't look like a bad guest.

Mu Bai withdrew his peripheral vision, made a gesture to invite the guest to take a seat, and then adjusted the position of the lamp according to his height after the guest sat down, and then he moved out a picture frame from the corner of the room.

After uncovering the frame cover and showing it to Fu Tian, ​​Mu Bai said in a Chinese that sounded rough and had a weird accent: "This is the picture I drew, please take a look."

Fu Tian immediately understood what he meant, and he looked at the frame carefully, his eyes lit up.

Seeing is worse than hearing a hundred times. He had already heard that the portrait drawn by this young man was very similar to himself, but he did not expect to be able to resemble him to this extent.

The person in the painting wears a round crown, has a high nose and deep eyes, and has several dimples on his face. His expression is slightly tense and rigid, but the corners of his lips are trying to smile. This person is the village chief who is leading the way for him.

Fu Tian is not good at painting, and the reason why he can distinguish the meaning from this small portrait is entirely because the painting is so lifelike, even the pattern on the hat is clearly visible.

Don't say that he walked all the way with the village chief, even if the person in the painting is a stranger to him, Fu Tian is sure that he can find someone in this village with this portrait.

He did not come here in vain, this boy is indeed quite capable.

The young man's eyes were burning, and as soon as he raised his hand, he handed over the labor fee handed over by the attendant to Mu Bai, and generously paid the full amount in advance.

Apparently, this young man looks carefree, but in fact, the intelligence collection is quite in place, and he has even checked the fee for Mubai's portrait.

Mu Bai opened the cloth bag, stretched out his hand to stir it, and found that the wheat grains in it were of good quality, the weight was acceptable after being shaken, he accepted the reward for one bag, and handed another bag to the village chief.

The village chief didn't even look at it after receiving it. He just said something carefully in the local language and backed out.

Fu Tian's eyes followed the two of them all the time. Seeing that he had sent the old man away, he covered the bright light at the door with a thick curtain and plunged the room into darkness. A more upright posture.

Mu Bai turned a blind eye to this, he adjusted the fabric back and forth, covering all the bright places in the wooden house, then lit the lamp and said:

"I'm going to start, are you going out and waiting or are you inside?"

This is obviously asking the attendant.

The attendant exchanged glances with Fu Tian, ​​and when he was about to speak, Mu Bai said, "You can be wherever you want, just don't block the light."

Mu Bai tilted his head, looked at Fu Tian again, and said in Chinese with a strange accent: "I have a quirk in painting, and I like to paint in the dark, so I will go to the next door and occasionally open the wooden door to observe the gentleman." He also showed the two the location of the lower wooden door, and opened it to show them the inside.

This is an unheard of quirk.

Fu Tian smacked his lips silently. He glanced at the busy young man in Yunnan, but his smiling eyes inadvertently glanced at the painting on the side. When he saw the content on it, his eyes lit up.

"Brother, do you know how to draw landscapes?" Fu Tian leaned over with great interest, and while looking at several landscape paintings on the ground by the light, he asked enthusiastically, "If you paint landscapes?" No need for shading? Then can we go out together, I want to draw a few pictures of me in the scene and send them back to my hometown."

The more he talked, the more excited he was, and he slammed his palm, obviously thinking that this idea was great.Mu Bai looked back at him helplessly, and said, "I'm sorry, I can't draw without being in the dark..."

Seeing the young man's appearance of "I have doubts", Mu Bai stretched out his hand and patted a portable cubicle propped up by bamboo poles hidden in the dark, showing another artificial dark color of this room under the light , the strength proves that the quirk that he can't play in the dark is still very stable.

With the speechless expression of the young man, Mu Bai walked into the cubicle gracefully, and quickly entered the working state.

In this small dark room where no one is disturbed, the only source of light is the light from the small wooden window. Mu Bai carefully looked at the young man through the small wooden window, when Fu Tian was a little uneasy and wanted to ask something. Suddenly, the wooden window was completely closed.

Fu Tim:? ? ? ?etc?Don't you watch me draw?

"Don't worry, I always do this when I draw, please keep the current action." Mu Bai said while spreading out a piece of paper on the drawing board.

Then, a very miraculous scene happened - a ray of light was reflected on the blank drawing paper through the small window that was obviously closed, and a face with a face was projected on the paper, although it was upside down, But the facial expression is lifelike, there is no difference at all.

At this moment, the owner of the human face seemed to be skeptical of Mu Bai's words, and was readjusting his facial expression to put on a serious look.

Mu Bai took out the charcoal pencil, squatted down and quickly and skillfully turned on the copying mode.

Don't get me wrong, this is not metaphysics or superpowers, it's just a learning and application of a knowledge point in junior high school physics.

The small window is actually a cover-up, and a small hole cut in the middle of the small window is the secret of the painting.

After the small dragged wooden window is closed, the brightest external light source in this dark room is only the small hole.

Therefore, when the requirement that the lamp, wicker chair, small hole and drawing paper are on the same straight line is met, the light propagating in a straight line will pass through the small hole, projecting the image of Fu Tim's face on the wicker chair onto the painting. on paper.

The position and distance of the drawing paper have been tested several times by Mubai to ensure that the projection image can be as clear as possible under the existing conditions.

While brushing and brushing to actually leave Fu Tian's face on the drawing paper, Mu Bai thanked the little friend who taught him the skills in his heart.

In the previous missions, a regular teammate of Mu Xiaobai's teammate used a lot of deception in order to persuade his semi-literate old antique teammate to study scientific knowledge well.

For example, the painting method Mu Bai uses now is one of the techniques he used back then.

Modern people who have received nine-year compulsory education basically know that this is because of the principle of small hole imaging, but for Mu Bai, a country bumpkin at that time, this scene made him feel extremely rare.

In the mouth of God's teammates, this painting method that seems to be cheating is actually an orthodox painting method recognized by the painter. This method of assisting painting with the help of various optical instruments developed rapidly after being discovered by Europeans, and promoted their development. The paintings have changed from flat paintings like the oriental ones to three-dimensional ones.

Because of the first mastery of the rules of the game of light and shadow, the artistic expressions of the East and the West have gone in two completely different directions, and have directly led to differences in medicine, the human body, and the perspective of viewing the world.

As for what the difference is...

Ahem, Mu Xiaobai, who doesn't like to study, fell asleep halfway through hearing it, so I don't remember it at all!

Fortunately, because the painting process was very interesting, Mu Bai memorized a life skill demonstrated by his little friend at that time, and learned the basic position calculation method under the repeated emphasis of his teammates. The child is now barely supporting himself and his younger brother.

...Although I have learned it, Mu Bai has to complain about it. The life of young people nowadays is too difficult, and the things to learn are really too difficult.

The little friend kept saying "learn mathematics, physics and chemistry well, and you will not be afraid to travel all over the world", forcing Mu Bai, an old antique, to memorize by rote, and learned a lot of things that he still barely understands until now.

In fact, this painting method based on the principle of straight-line propagation of light does not have too many restrictions on the scene and raw materials. As long as the conditions are met, imaging can be carried out by moving a light-shielding box.

The reason he's going to be so mysterious in the house... Hey, it's all because the locals are so curious.Anyway, it is also a commercial secret, so Mu Bai had to wrap it up.

My friend said that the more complicated the process, the lower the probability of being cracked.

For example, when Mu Bai just finished copying, he saw the face on the drawing paper suddenly enlarged.Mu Bai calmly straightened the drawing paper, and even lighted the oil lamp. Just as he rearranged his movements, the small window behind him was slowly pushed open.

Mu Bai turned his head calmly, and said what he always said to his black eyes flashing with curiosity and excitement: "Please sit back, the painting is not finished yet."

Yes, every time, from the earliest experiments with his younger brother's wooden text, and every time he draws, someone will quietly open the small wooden window.

Some people were worried that something happened to him if he hadn't moved for a long time, some people were simply curious about how he would draw in the dark, and some people thought he had a secret to crack.

Just like every student feels that the teacher won't find out about their small movements during the exam, these people who are acting as models outside the window also feel that Mu Bai will not know that they are peeking.

But it's a pity that their every move will be projected onto the canvas. Although his back is facing the visitor, Mu Bai knows exactly what they are doing.

After a lot of times, Mu Bai thinks this is quite interesting, and he will choose to turn around at the right time to scare them.

Fu Tian, ​​who was really taken aback, touched his nose and explained weakly: "Well, I'm sorry, I'm a little anxious..."

Oh, this is the first time I heard such a reason.

Mu Bai stopped the charcoal pencil in his hand, and gave this man who had worked so hard to make excuses a little respect—and took him to his own toilet.

Struggling to relieve himself under the staring eyes of a young boy and a child, Fu Tian walked back to the studio hand in hand.After sitting down again, such a sunny young man inexplicably became a little... cowardly?

Mu Bai tilted his head and cast a puzzled look. He didn't know why the young man seemed to shrink back after receiving the look.

Could it be that he was found guilty of peeping?Forget it, I don't understand the thinking of young people.

Mu Xiaobai, whose real age cannot be said, shook his head, and walked back to the small black room with his hands behind his back.After the others disappeared into the house, Fu Tian breathed a sigh of relief without a trace.

It's not that he's timid, it's that the scene he saw before was too scary.

As a person who came to make a portrait, it doesn’t matter if he enters a dark room. The painter glanced at it and flashed to the next door, and observed that he was also passing through the small window that was closed and never opened again. Is Fu Tian curious? Can you not be nervous?

After all, he was born in an unfamiliar foreign land, and there were many legends about the Dian people, which inevitably reminded him of some strange things.

In addition, this child has never said before that it cannot be regarded as a painting process, and his identity is still a bit special, um... it is better to be cautious.

Fu Tian, ​​who convinced himself, made an ungentlemanly move.

Unexpectedly, as soon as the small window was pushed open, he saw an extremely horrifying scene.

A small lamp was burning in the pitch-black hut.Candles are not yet popular here, and most of the lamps used are oil lamps. Oil lamps have a strong smell and low brightness, so although they are lit, they can only illuminate a square inch of land.

In his eyes, the little boy with his back to him is painting with a brush.He was obviously very careful, and hardly made any sound when he opened the small window, but the boy suddenly turned to look at him as if he had eyes behind him.At that moment, Fu Tian seemed to feel a chill rising from the soles of his feet.

The child was originally a cute face with red lips, white teeth and big eyes, but in the dark room, the eyes are extraordinarily large. The faint eyes and the bigger forehead because of the bald head make him look like a ghost boy in a ghost story, especially creepy. .

What was even more frightening was that he saw his own face appearing behind the little boy - that face was exactly the same as what he usually saw in the bronze mirror!

This, is this the secret technique of the Luoluo tribe?It's like the Gu technique of the Miao people!

The author has something to say:

Hmong:? ?I feel offended, why do I have to CUE without me!

You guessed the camera yesterday, the author is about to cry, you have taken too many steps, the author has no sense of accomplishment! !I won't show off anymore woo woo woo.

In fact, the answer is similar. This method of painting using the principle of small hole imaging is actually the principle of the camera. The camera is nothing more than changing the drawing paper into a raw material coated with photosensitive materials, and then using light as a brush to transform the image and The shadows only record it.

(whispering) According to the scientific and technological capabilities of the early Ming Dynasty, photosensitive materials were produced, but color rendering materials were not very easy to produce, so forget about cameras.

This painting technique in this article is called the camera obscura, also known as the optical instrument-assisted method. The little cutie who is learning to paint may have heard these terms when learning the history of painting. This painting method was very popular in medieval Europe.

The early paintings in China and the West are actually the same. Everyone is 2D. Strictly speaking, the 2D in the East is more beautiful (hey), but the dividing line between China and the West is the emergence of this painting method. Borrowing this auxiliary painting method , Westerners began to have the concept of three-dimensional and shadow, with the proportion, and thus began to go to a different road.

Of course, this kind of painting method is not so troublesome in the later stage. Using the refraction and reflection of the mirror, the concave-convex mirror can turn the [darkroom] into a small box (similar to the obscura of an old-fashioned camera), and the painting does not need to be erected, but It is possible to sit and draw, and its difficulty is similar to that of drawing with sulfuric acid paper.

Actually more famous

Because it is very convenient and entry-level is low, so in the early days of the camera, because of the extremely long exposure time, many people would rather choose portraits than use cameras. After all, smiling at the camera for half an hour is really not a human thing.
