Chapter 789: Bullied by the leader and cried.
Facing the leader's complaints, Qubing and the others naturally had nothing to say. This was just a prototype that could just meet the needs of filming. The first purpose of making it was to be usable, so how could they care about its appearance?
"Chief, are we going to take pictures now?" Ao Fei didn't care about the leader's complaints, but was eager to show it in front of Luo Chong.
"Take pictures? This word doesn't sound good. I think it should be called photography, or taking pictures. You don't have to worry. You have been traveling for two days. It's noon now. Let's eat first. Tell me the principle of your design of this thing. It's not too late to take pictures in the afternoon."
Luo Chong immediately rejected their proposal, and then asked the maid at home to prepare lunch. He ate with the group of researchers in person and talked about their work and research during this period.
After listening to the three people's stories, Luo Chong asked Wen Nong, "So the reagent No. 17 that you made was the one that fixed the image in the end?"
"Yes, chief. Actually, it was Qu Bing who suggested using that thing for testing. I didn't help much." Wen Nong was humble at this time.
"Yeah." Luo Chong nodded, but didn't pay attention to it. Instead, he continued to ask, "You said that this reagent No. 17 has a green metallic flame reaction?"
"Yes, chief." Wen Nong didn't know why Luo Chong paid attention to this, but he nodded to show his affirmation.
"Then when you go back, mix this thing with a little gunpowder, and then use glue to make it into a paste. I want to apply it to the bullet head to make a green tracer bullet to correct the trajectory. The amount doesn't need to be too large. Each bullet only needs to burn for a breath of time, because the bullet only needs such a short time to hit the target.
Also, since it is a metal, let's give it a name. It's called 'barium', barium with a shell next to the gold character." Luo Chong made a decision immediately and said.
"Yes, Chief, I'll take note of it." Wen Nong also hurriedly agreed, and even put down his bowl and chopsticks, and took out a small notebook and a portable brush from his arms to record it.
Luo Chong just confirmed from Wen Nong's description that this unknown metal was barium. Barium is not a rare metal. On the contrary, its content in the earth is even more than iron, but it just does not often exist in the form of metal, because barium, like aluminum, is a mineral that can only be reduced to a single metal by electrolysis.
It cannot be reduced by heating with charcoal, and there is a green flame reaction. What else is this but barium? Moreover, barium sulfate does have the effect of being a fixer, but Luo Chong does not often come into contact with this thing. Some things have long been forgotten, and can only be remembered when reminded.
Seeing that the topic was gradually being dragged away, Qubing boldly asked Luo Chong, "Chief, can you give us an evaluation of photography?"
Ao Fei, who was standing aside, also pricked up his ears when he heard him say this, and stared at Luo Chong expectantly.
"Evaluation? You want me to praise you guys?" Luo Chong teased them and then said.
"You can praise them if you want. Ao Fei was able to discover its potential value from daily experiments and boldly put it into practice. He used the principle of pinhole imaging to design a photography box with adjustable focal length. This is very good and worthy of recognition.
Qubing, you have played an important auxiliary role in Ao Fei's experiment in such a short time, and you have undertaken the research and development of the later photo washing process. This is also very worthy of recognition.
How about it, are you satisfied after the praise?" Luo Chong continued to tease them.
Ao Fei blushed and felt a little embarrassed, but he didn't dare to respond to the leader's words. Instead, he took the opportunity to ask Luo Chong a question.
"Chief, it stands to reason that in the same environment, light should be irradiated in a straight line, but why is the image reversed after passing through a small hole? I have never figured out this question. Please teach me."
Luo Chong slapped his forehead and replied speechlessly, "Isn't the pinhole imaging experiment used to prove your theory? Light propagates in a straight line in the same medium. You can draw a diagram of the experiment yourself, and then connect the entity and the inverted image through the pinhole and you will understand."
"Oh, so that's how it is. I've been dwelling on this dead end. Hahaha, yes, why didn't I think of it? Because light propagates in a straight line, when it passes through the pinhole, the light above shines on the bottom, and it becomes an inverted image. Thank you, chief, I understand." Hearing Luo Chong's reminder, Ao Fei immediately became excited. The problem that had troubled him for a long time was finally solved, and he even felt like he had an appetite for food.
Luo Chong looked at Qubing again. This guy was obviously not satisfied with his praise, so he asked him, "Do you have anything else to say?"
"I feel that the leader looks down on our photography skills. He is not sincere when he praises us. Why?" Qubing asked recklessly. Only he dared to say this because of his relationship with Luo Chong. Wen Nong and Ao Fei next to him were about to shove their faces into the bowls, and pretended to be dead and pretended not to hear the narration.
After hearing what he said, Luo Chong put down his chopsticks, "If you ask this, then I have to discuss it with you. Suppose you are a photographer who makes a living by taking photos for others. I am your customer. If you cannot meet my needs, I certainly won't praise you."
Qubing also got serious. He put down his chopsticks and looked at Luo Chong seriously and replied, "Then I wonder what the leader's requirements are?"
Seeing that this kid fell into the trap, Luo Chong smiled and asked, "I want to take a half-body portrait. Can you do it?"
"Of course." Qubing immediately nodded affirmatively and added, "We can even take full-body photos. The photos sent to the leader are full-body photos."
Luo Chong waved his hand at this time, "I'm not talking about half-body photos, but large photos as large as half-body. Can you take them?"
Qubing wanted to continue with his neck stiff, but he choked when he heard Luo Chong's tricky request. He looked at Ao Fei beside him uncertainly and asked in a low voice, "Brother, can you take it?"
"Theoretically, it's possible. Just make the camera box bigger and change to a bigger lens." Ao Fei also chewed his rice and said in a vague voice.
"I can." With Ao Fei's support, Qu Bing stiffened his neck and became stubborn again.
"Can you? How do you take it? Make a silver-plated copper plate that is half the size of a person? How much does it cost? I'm poor and can't afford it. Goodbye." Luo Chong continued to tease him.
Qu Bing's face turned red. Luo Chong was the leader of the Han tribe. How could he be without money? Qubing knew that this was Luo Chong's satire on their high cost of filming, but they had no other solution for the time being, so facing this problem, he could only admit defeat for the time being, "We will try to change the material of the photo to reduce the price, but not many people will ask for such a large photo, right?"
"Okay, even if what you said is true, no one will take such a large photo, then I will ask one last question, I don't want to think about color photos for the time being, I will just say black and white, I think the photo you took of me is very beautiful, I want to enlarge it and make a few more copies to send to my family, I also want to reduce it and make a few more copies to put in a book, can you do it?" Luo Chong asked again.
"The leader is bullying, who would make such a strange request, the photo is originally unique, why do you want to enlarge and reduce it, and make a copy, you are deliberately making things difficult for us." Hearing Luo Chong's weird request, Qubing pouted and acted like a child.
But Luo Chong said seriously, "But I can do all the requirements I just mentioned!"
The people across the table all looked at Luo Chong with wide eyes. The leader had just listened to their explanation of the principles of photography, and he had come up with a way to improve it to this extent?
Although they all knew that the leader's wisdom was unparalleled in the world, this was too abnormal. They had spent more than a week to succeed, but the leader improved it after listening to it once.
