Chapter 786 The Birth of the First Camera
The two people who had assigned their work soon became busy again. Ao Fei went to improve his photo box, and Qu Bing went to the mechanical group to order a bunch of silver plates for experimental materials. Fortunately, the research institute had sufficient reserves of various materials, even precious metals such as silver, and there was enough for them to squander.
The Han tribe was not short of silver, and the Han tribe did not use silver as currency transactions. As long as the silver was not made into silver coins, it could not be circulated in the market, so the two sides did not have to worry about them embezzling these experimental materials.
After preparing the silver plates, Qu Bing went to the chemistry group to find the head of the group, Wen Nong, and first asked about the news about the bullet body materials and processing experimental equipment in Xingang County. When he learned that they had not been delivered yet, he pulled Wen Nong to talk about his photo technology.
"Brother Wen, the two materials you gave me cannot be stopped once they react. Is there any way, or other reagents, to stop the reaction when they are halfway through the reaction, and something that can be preserved for a long time." Qu Bing asked while sitting beside the experimental table.
Wen Nong stopped his research on reagent No. 17 and asked in confusion, "Reaction, what reaction? Aren't you just trying to make the silver nitrate react? Why do you want to stop the reaction?"
"Yes, just to make it react. The sodium sulfite you gave is indeed very useful and has had some effect, but the reaction effect is too strong, so it still cannot meet the requirements. I was wondering if there is any way to stop the reaction when it is halfway through."
"Stop the reaction halfway?!" Wen Nong frowned. How could he know if there was any way? How could you do an experiment halfway? But after thinking about it, he still said.
"It's not that there is no way to stop the reaction. You just need to destroy its reaction conditions. For example, some reactions must occur in an acidic environment, so you can add alkali to neutralize the acid. Some reactions require high temperature conditions, so you can find a way to cool it down. Once the necessary conditions for the reaction are lost, the reaction must be stopped."
"What about the reaction of photosensitive materials? Brother, didn't you say that reagent No. 17 can turn off the light? If you add some when the reaction is halfway through, can it stop the photosensitive reaction?" Qubing looked at the glass test tube filled with transparent liquid in his hand and suddenly asked excitedly.
"This, I can't say for sure. Reagent No. 17 is a new thing. I don't know whether it is useful for the experiment you mentioned. But if you need it, I can provide some for you to experiment. Anyway, I am also developing its uses here. If I can add a new use, I will not lose anything." Wen Nong thought for a while and said.
"It would be great if you can participate, we will definitely succeed." Qubing immediately became happy.
"What else do you need now?" Wen Nong also asked with a smile. Qubing was assigned by the leader to lead the research and development of weapons. In addition to his relationship with the leader, it is clear that he will be a powerful person in the future. It is definitely right to deal with such people more, so Wen Nong does not mind giving him some help within his ability.
"Hehehe, I need silver nitrate solution and sodium sulfite solution, and reagent No. 17, if it can also be made into a solution." Qubing immediately asked for things with a smile.
"Didn't I give you so much? It's all used up now?" Wen Nong asked in surprise, but seeing Qubing with a smile on his face, he could only complain, "You used it up so quickly."
Then the two of them took the three bottles of potions they needed to the darkroom of Ao Fei's optical group. As soon as they entered the dim room full of red light, Wen Nong asked in surprise, "Don't I say that since you know that silver nitrate is afraid of light, you dare to turn on the light?"
"Brother Ao discovered that silver nitrate is not afraid of red light, so we got a red light for lighting." Qubing explained while working on the side.
"Is that so? This is a useful discovery." Wen Nong responded and began to look around. When he saw two people applying potions on a metal plate, he asked curiously.
"Brothers, what are you doing? You have been working on it for several days."
"Hey, old Wen, just wait and see. Don't be surprised by our research results. Qubing and I are about to change history." Seeing his experiment add new power, Ao Fei was also very excited, as if he had seen his experiment succeed, won the leader's commendation, and hung his photo on the school wall from then on, admired by thousands of people.
"Tsk, change history, when has our institute not changed history?" Wen Nong said with some disdain.
"That's different. You are changing history, while Qubing and I are changing the way of recording history. How will it be written in history? On a certain day of a certain month of a certain year, someone from the Han Tribe Research Institute developed a chemical dye that can dye rubber. From then on, the Han Tribe had white rubber, and someone made a great contribution to the rubber application field of the Han Tribe." Ao Fei said, imitating the tone of written records.
"Yeah, if it's history, of course it should be recorded this way." Wen Nong replied as a matter of course.
"Hehe, but we can not only record words, but also record images, leaving your appearance forever for future generations to see. When the time comes, hang your photo on the school wall so that all students can see it. Look, this is the show-off who studied rubber dyes." Ao Fei continued to tease.
"Hahahaha" Qubing also laughed out loud because of him.
"What? Leave a picture?!" Wen Nong was not as angry as he imagined, but he was curious about what he said about leaving a picture.
Qubing chatted with his mouth, but his hands did not stop moving. He quickly made a silver plate and sealed it in a light-proof dark box. While the silver nitrate solution on it was not dry yet, he immediately pulled Ao Fei out and called Wen Nong.
"Brother Wen, we are about to take a picture, don't you want to come and see?"
"Come, of course, I'm itching to be teased by you two." Wen Nong muttered and ran out quickly.
When he came to the outside of the darkroom, he saw a chair in front of the hexagonal booth. Ao Fei was already sitting on it, and Qubing was standing behind a wooden box on a tripod, quickly inserting the silver plate into the film slot.
"Old Wen, I proposed this technique and was responsible for the development of the equipment. I should be the first person in the Han tribe to take photos. Qubing also put a lot of effort in the post-processing, so he is the second, but since you are here to provide technical support, we will let you rank third." Ao Fei sat there, his mouth was not idle, and he was still teasing Wen Nong.
"Brother Ao, don't talk anymore, I'm going to start." Qubing greeted him and covered himself and the photo box with a black cloth.
"Oh." Ao Fei hurriedly responded, then sat down seriously and looked at the camera in front of him.
"I'm starting." Qubing greeted him, and immediately pulled out the sunshade to start exposing the film. He counted four breaths in his mind and put the sunshade back.
"I'm done, brother, let's go back quickly, the film should be dry soon." Qubing greeted him, spread his legs and started running towards the darkroom, and Ao Fei hurriedly followed behind.
"No, what on earth are you doing? You've finished before I can understand it?" Wen Nong didn't understand what was going on, and saw the two of them go back again, without explaining to him.
"It's too late, Brother Wen, come in quickly, we have limited time, and we need your technical support." Qubing shouted without looking back when he ran to the door of the darkroom.
"Oh, I'll be right there." Although Wen Nong had many questions in his mind, he also knew that experiments were very time-sensitive, so he didn't delay and followed them into the darkroom.
Bang, the doors and windows were all closed, and in the dark room where you couldn't see your hand in front of you, Ao Fei fumbled to turn on the red calcium carbide lamp, while Qubing started to work on the experiment at the operating table, and Wen Nong hurried over to stand by.
He saw Qubing take out a silver plate with medicine from a particularly flat wooden box, and then put it in the first ceramic plate filled with sodium sulfite solution. He also used a pair of bamboo tweezers to move the medicine back and forth.
"What the hell are you doing? This, this, this is the scene I just saw outside!!!" Wen Nong was about to ask what the two of them were doing, but before he could finish his words, he saw the scene he had just seen outside appear on the silver plate that Qu Bing was fiddling with. The pavilion, the stone table and stone bench, and the show-off Ao Fei sitting in the middle, were exactly the same.
Qu Bing did not explain, but was busy with his operation. When he saw that the silver plate began to develop and gradually reached the maximum clarity, he quickly used tweezers to fish out the silver plate, then rinsed it twice in the basin that had been prepared next to it, and then quickly transferred it to another plate containing the No. 17 reagent solution.
After the silver plate was put in, it was calm, as if nothing had happened, but Qu Bing and Ao Fei were so excited that they almost jumped up. After so many experiments, this damn picture was finally frozen.
Qubing carefully took the silver plate out of the potion, and then rinsed it with clean water several times. Seeing that the picture on it was finally frozen forever on the bottom plate and did not change anymore, he finally breathed a sigh of relief.
"Two senior brothers, look, this is the first photo of our Han tribe. From now on, we finally have the technology to freeze time forever on a carrier. When we are old, we can also take out the photo to show our great-grandchildren what we looked like when we were young, hahahahahahahaha"
