Chapter 136 Film Camera
[Difficulties of Emperors of Different Dynasties]

[This was the case during the Qin Dynasty. Commoners only had to build the Great Wall, the Great Road, the Imperial Mausoleum, the Palace, the Lingqu Canal, and pay heavy taxes. However, Qin Shihuang had many things to consider.]

[This was the case during the Han Dynasty. The peasants only needed to deal with land annexation, class blockades, and the Yellow Turban Rebellion, but the foreign relatives had to consider many things.]

[The Three Kingdoms was like this. Soldiers only had to fight, cultivate land, pay taxes, and be burned or flooded. However, the King of Wei and Wu had many things to consider.]

[This was the case in the Jin Dynasty. Civilians only needed to be robbed, exposed, blocked, and fed meat porridge, but Emperor Hui of Jin had many things to consider.]

[In the Sui Dynasty, the common people only had to build canals, build dragon boats, repair palaces, and conquer Goguryeo, but Emperor Yang of Sui had a lot to consider]

Qin, Xianyang City.

I have seen many videos from Tianmu before, all of which are flattering, such as "The charming and lovely ancestor, 198 cm tall, with eight-pack abs, and a sword as tall as Cao Cao, doesn't he just want to be immortal? What's wrong with him? Why can't Tang Seng jump into the mouth of the civilized ancestor?" and so on.

This made him feel elated for a while, thinking that after thousands of years, someone finally understood his painstaking efforts.

At this moment, looking at the "sarcastic" comments in the comment section, Ying Zheng's face turned blue in an instant.

"I will enjoy the remaining glory of the sixth generation alone, and I will not bear the blame if the second generation dies."

"Daqin's carefully selected non-stick pan!"

"If Qin Shi Huang were alive today, he might not even be able to eat at the table."

"This kind of people just need to be dragged to build the Great Wall for two days!"

With every sentence Ying Zheng recited, the veins on his forehead twitched and his expression became increasingly gloomy and unfriendly. If anyone was to say who wanted the Qin Dynasty to prosper forever, he was the one with the strongest desire.

Therefore, after unifying the six kingdoms for so many years, Qin launched wars in the south and the north and built highways in order to eliminate the external threats to Qin. Internally, Qin has been committed to unifying the writing system, weights and measures, banning private schools, burning poetry and books, and conducting many tours in order to eliminate the influence of the six kingdoms.

In addition, he killed two troublemakers, Zhao Gao and Hu Hai, for the sake of justice, thus eliminating another trouble for the Great Qin and the people of the world.

All of this was the result of his hard work for the people of Qin. Now it has become the reason for criticism from future generations. How can he not be angry!
"That's true!"

"I attacked the Xiongnu in the north, conquered the Yue in the south, built the Great Wall, constructed the Chidao and dug the Lingqu Canal, all for the sake of the people of this country. What's wrong with that?"

"I am the ruler of all the people in the world. My achievements in unifying the six kingdoms are comparable to those of the Three Sovereigns and Five Emperors. Building imperial mausoleums and palaces is my due responsibility. What's wrong with that? Ahem."

"Li Si, Feng Quji, tell me, what did I do wrong?"

Li Si and Feng Quji looked at each other, sweat dripping down their foreheads, thinking, Tianmu is sick again. Why do you keep poking His Majesty's lungs?
Ming, Jinling City.

Zhu Yuanzhang and others sneered, saying that both the Qin and Sui dynasties perished because of their vanity and disregard for the people's strength.

This is the public opinion. He really couldn't understand why later generations had such a high evaluation of Ying Zheng. He only realized now that only some people felt this way.

Unifying the six kingdoms, abolishing feudal fiefdoms and establishing counties, standardizing the writing system and the wheel gauge, and standardizing weights and measures are indeed great achievements, but it is undeniable that he was ambitious, greedy, cruel and ruthless. He would rebuild the palace of a country he conquered, or the Afang Palace and the Mausoleum of the First Qin Emperor. He was obsessed with immortality, fought wars in the south and the north, built the Great Wall, the Great Road, and made six tours of justice.

Each and every one of these events may seem like great achievements, but in fact they are all soaked in the blood and tears of the people.

These projects were too large. Even in later times, such as the Three North Shelterbelt Project and the Yellow River Harness, they were all planned for decades. They were not intended to be completed all at once, but rather the project period was extended to avoid wasting time and effort.

Moreover, these projects did not have machines like those in later generations to replace the hard labor, and the food, clothing, and medical care were all inadequate. Building the Great Wall and other things was almost like committing suicide, wasn't it?
In the comment section, if the boss asks for a team building on the weekend or to get off work overtime, the people would wish the boss's entire family would die immediately. But how come they turn a blind eye to the various cruel things that happened during the Qin Dynasty?
"You don't feel pain until the stick hits you." Zhu Yuanzhang could only attribute the reason to this. He was born into the lowest class of common people and understood the sufferings of the people. Therefore, after he ascended the throne, he always practiced thrift and economy, reduced taxes and levies, and lived in harmony with the people.

"The Two Jin Dynasties. What a bunch of rotten fish and shrimp." Many people held back and did not say anything, only complaining in their hearts.

One of the comments was very true... that is, in this era, people have to work hard to live, so there is no such thing as beauty. Especially for women and children... it's okay if they are ugly, but those who are pretty will be coveted.

The same goes for children... During festivals, such as the Lantern Festival, when there are many people and eyes, children are most likely to be kidnapped by thieves. In comparison, the future seems so peaceful... People really can't understand why they want to travel back to this broken era where it is difficult to even eat meat.

"It seems that their aesthetics are quite special. This may be the influence of the TV series they are talking about?" Liu Ji said with a smile. They have seen these TV series and short plays, such as 1566, The Three-Body Problem, and A Mortal's Journey to Immortality.

"It's not impossible." They had previously seen videos complaining about the serious inconsistencies between the characters, costumes, and environments of costume dramas. If they didn't deliberately try to find out, they would really believe what they saw in the TV drama.

"Let them give 80% of their salary to Qin Shi Huang and they will behave themselves"

"No, there are still people who are fans of the Jin Dynasty?"

"Famous quotes from the Wei and Jin Dynasties: Wei, Jin, Southern and Northern Dynasties, absurd and beautiful, haven't you heard of it?"

"Beauty means: being cooked in the same pot?"

"This is what happened during the Yongle Dynasty. Fang Xiaoru's entire clan only needed to be executed, but Zhu Di had a lot to consider [狗头]"

"The Qing Dynasty was like this. The Buddha only needed to cede territory, pay compensation, and declare war on England, but the Western powers had to consider many things."

[A parent said: My child recently asked how people were captured on film in the past]

[In fact, the principle of movies and cameras is the same. Movies are just played continuously at 24 photos per second, which uses the visual persistence phenomenon of the human eye, so it looks very smooth. For example, you have seen this on the Internet, where three pieces of paper rotate at a certain speed, and it looks like the people in the picture are moving.]

[Common films mainly include black and white films and color films. The substances responsible for photosensitivity are all silver halide particles. The halogen element is actually an element in the series of chlorine, iodine, and bromine. They react with silver to form silver halide. Silver bromide was generally used in the past.]

[After you press the shutter button, light will shine on the film filled with silver halide crystals, causing the silver halide crystals to undergo structural changes and gather together with the silver halide crystals next to them that have also been exposed to light, forming a latent image. This latent image cannot be seen yet.]

[The stronger the light received by a certain part of the film, the more silver halide crystals will gather and deform. The silver halide crystals in the part with weak light will not change.] [The next two steps are washing and enlarging. Washing is to process the film itself, including development and fixing. Developer and fixer are needed. Among them, Kodak D-76 is the most famous developer. Its composition is]

[The developer can restore the previously photosensitive silver halide crystals into black metallic silver particles, while the non-photosensitive silver halide will not change at all]

[Then use a fixer to wash away the unchanged silver halide crystals, and finally use clean water to wash off the liquid on the film, hang it up to dry, and the film is done.]

Jinling City.

Everyone got busy again. This is the principle of photography in later generations. It is really simple.

“What a clever idea!” Zhu Yuanzhang, Zhu Biao and others were all enlightened. Isn’t this the principle used in short videos like the sky screen?

In other words, as long as they make this thing, they can naturally hire people to film everything like movies, TV series, short plays, etc. This is the same as the Huangmei Opera we watch every day. When they hold sacrificial ceremonies in the future, won’t they be able to take photos or even film the process as a souvenir?

There are also various historical moments that will become precious documents in the future. Let’s see who the hell dares to slander me and draw me like a bent slipper!
This is really unreasonable!

And by then, there will be no need to dig up my mausoleum anymore!

Zhu Yuanzhang's mind raced. If there was anything else that made him feel sick at the thought of it, apart from the loss of his country and his unfilial descendants, it was the possibility that his mausoleum had been dug up. Fortunately, from the information from the sky curtain, he learned that his mausoleum had not been excavated until later generations.

The ministers were also somewhat happy. After the video camera and camera were invented, the entertainment items would inevitably explode, and various TV series would appear. For example, the Demi-Gods and Semi-Devils, The Legend of the Condor Heroes, and The Three-Body Problem, which we had seen on the TV screen, no longer needed to be explained by Xiao Shuai.

No matter what, who wouldn’t want to record these precious moments, such as family gatherings during festivals, wedding nights, and success in the college entrance examination?

This machine is more important than a camera.

In the Science Department, a group of people began to take stock. Halogens can be replaced by chlorine gas instead of bromine. Chlorine gas will be decomposed when saturated salt water is electrolyzed. The composition of the developer also seems easy to make, but the so-called developer is a bit difficult to deal with.

They looked at each other, and probably knew what the other was thinking.

Hexing Tea and Snack Shop.

"If a camera is really invented, we would sell everything we have to buy one." All the diners were delighted. They also understood the value of this machine, which was more important than a phonograph.

The phonograph created an industry, namely the recording and sales of opera songs. After all, not everyone could afford to listen to the songs of the courtesans on the Qinhuai River flower boats.

At the beginning, even if one, two or three courtesans were unwilling to condescend to sing for those peasants, they would secretly get angry when they saw huge amounts of money flowing into the pockets of those who had mediocre singing skills and were not in their eyes. At the same time, they realized that this money was much more innocent and easy to get by comparison, so they would no longer be reserved.

It's not fun just to listen.

Shopkeeper Wan rubbed his hands excitedly. He had invested in a small electrical appliance store but he did not usually run the business.

At this time, all the electrical appliance stores in Jinling City were on the same starting line. For a latecomer like him, this was undoubtedly a better start.

He also knew that this was not Tianmu's deliberate difficulty but that the subject of chemistry in the Ming Dynasty started very late, so many things that were easy to make in later generations were unheard of today and needed to be tried out step by step.

This has both advantages and disadvantages. The disadvantage is that it requires a lot of manpower and material resources to conduct research. The advantage is that it fully mobilizes the forces of all sectors to conduct research, and at the same time makes it difficult for envoys from various countries to copy these technologies back.

[The more black metallic silver particles are left on the part of the film that is exposed to strong light, the less transparent the film is. On the contrary, the silver halide crystals in the originally dark part have not changed much and are finally washed away by the fixer, making the film more transparent.]

[So the brightness of the film at this time is exactly opposite to the scene being photographed, which is why it is called negative film]

[The next step is to enlarge the film, which means using an enlarger to transfer the washed and dried film onto photographic paper to turn it into a photo]

[Before enlarging, you need to fix the film on the film holder of the enlarger, then turn on the light to pass through the film, and after being focused by the lens, a clear image is projected on the photo paper at the base]

[The surface of photographic paper is also coated with emulsified silver photosensitive emulsion, which will also undergo structural changes when exposed to light, and then it needs to be developed and fixed again.]

[The trick is here. The light and dark information on the film is exactly opposite to that in the real world. After reshooting, the light and dark information on the photo paper is exactly opposite to that on the film. In this way, negative and negative equal positive, and a normal photo is obtained.]

[The structure of color negative film is similar to that of black and white film, the difference is that there are three layers of photosensitive layers on the top of the film, which can sense different wavelengths of light respectively and finally mix them into the colors you see with your naked eyes]

[It’s just that this color is the same as the black and white overlay, which is exactly the opposite of the real color]

"How did they come up with these things? I still don't understand it after watching them for a long time."

"The camera was not invented by one person, but was gradually perfected over a long period of time."

《Film cameras have been withdrawn from the market, and are only still used in some movie shootings》

The biggest advantage of film is that photos can be enlarged infinitely without mosaics. The theoretical maximum resolution of film is the width of a silver iodide molecule.

What to do with movie sound?

《The sound was recorded separately, so the purpose of the board during filming is to align the sound》

Tang Dynasty, Chang'an City.

Li Shimin was also amazed. The principle of this camera was very simple, but the actual process was extremely complicated, not to mention the two parts of developing and fixing.

"Such a good thing. They have eliminated it?" Everyone was helpless.
"Did they use a cell phone to take the photos?" Everyone knew the meaning of computers, cell phones, software, etc. Film cameras should be the product of the Second Industrial Revolution, and the Third Industrial Revolution, such as cell phones and computers, would be even more troublesome.

A lot of people have seen the series of "Madame Rong teaches Ziwei how to read circuit boards", "Madame Rong teaches Ziwei how to analyze stress", and "Madame Rong teaches Ziwei how to plant".
I know every word, and when they are put together, it's like a heavenly book, so I won't mention it.
