Chapter 793 Street Photography Master Luo Chong
Since we have photography technology, we should certainly use its ability to record history. An old man like the Rat Witch who brought the calendar to the Han tribe is completely worthy of being remembered by future generations. That’s why Luo Chong thought of inviting the Rat Witch to take photos. Otherwise, he might not have the chance to take photos in the future.
As a child who grew up in the Han tribe, Qubing was naturally very familiar with the Rat Witch. He immediately ran to the office area of the Imperial Observatory to invite the Rat Witch. The old man hadn’t figured out what was going on, and Qubing didn’t know how to explain it to him. He only said that the leader wanted to take a photo of him, but this new term was automatically understood by the Rat Witch as a portrait.
But when he followed Qubing to the bottom of the building, he found that Luo Chong didn’t bring any drawing board, paper, or pen. Besides, even if he wanted to draw a portrait, shouldn’t it be done indoors?
With a head full of question marks, the Rat Witch was directly pulled in front of the sundial by Luo Chong, and he asked in confusion.
"Chief, are we going to paint here?"
"Not painting, but taking photos, which are much clearer than painting." Luo Chong explained, and quickly inserted a film in his hand.
"Oh, how can I cooperate? Can you find me a stool? I'm old and can't stand for so long." The Rat Wizard said with the cane in his hand.
"No, no, you old man just stand in front of this sundial, right, put one hand on it, stand still, look at me, look at the box in my hand, eh, right, okay, stand still, okay."
Luo Chong directed the Rat Wizard's actions while busy with the operation in his hands. Just as he finished speaking, the film in his hand was also exposed, and he just had to wait to take it back to be developed and enlarged onto photographic paper. The Rat Wizard
was confused. Didn't he say a portrait? This, it's ready now?
Luo Chong was afraid that the old man would misunderstand and think that he and his friends were teasing him, so he asked Zhan Ying to take out a photo taken a few days ago and explain.
"Rat witch, look, this is the new technology invented by Qubing, it's called photography. Just stand in front of this small box for a few seconds, and it will record everything you see, and turn it into a black and white painting. We've just taken a picture for you, and you'll be able to see the finished product tomorrow." "
Oh, photography, that's amazing, you can draw it just by looking at it, and it looks so real, Qubing is really good, I knew he was extraordinary when he was a kid, he's definitely going to be great when he grows up." Although the rat witch didn't know much about photography, he knew it was a technique for drawing portraits quickly, and it was invented by Qubing, so he was very pleased, pointing at Qubing and started praising him.
Of course, Luo Chong didn't have time to chat with the old man here, he was here to do an experiment, and seeing the sunset getting lower and lower in the evening, Luo Chong directly gave Qubing a color, and then took Tang Yao and Ao Fei away first.
The group first went to the top floor office of the government building, where they took a bird's-eye view of Hanyang City from a high altitude. Then Tang Yao also learned to use a camera to take a photo of Luo Chong sitting behind a desk and writing.
Then the group ran to the outside of the windmill without stopping. Luo Chong asked Tang Yao to stand in front of the tall windmill and took a photo of her.
Just as they were about to go outside the city to take pictures of the city wall, Qu Bing finally sent the rat witch back and ran over.
Then the group climbed up the city wall to take pictures of the river and rice fields in the distance, as well as the sailboats docked at the dock outside the city. They also took pictures of the tall city wall, the soldiers standing guard on the tower and the war drums from an upward angle under the city wall.
When the sun finally set in the western sky and dyed a piece of fire clouds red, the convoy that Luo Chong had sent to Gongye County to escort equipment and experimental equipment also returned. Luo Chong immediately ordered them to stop on the street, and then took a few photos of the convoy, and then he was satisfied and took everyone home.
First, they arranged for a convoy to put the equipment sent by Gongye County in the vacant military camp in front of Hanyang City, and then Luo Chong started to go home and take them to develop photos.
The temporary darkroom that was previously placed in the yard has been dismantled. The maids transformed a small study into a proper darkroom according to Luo Chong's order. Since he has already developed mature photography technology, Luo Chong doesn't mind setting up a set of such a developing room for himself, so that he can play with photography when he has nothing to do in the future.
In the newly renovated darkroom, Luo Chong, Qubing Aofei and the other two were busy developing the photos taken during the day, and Tang Yao and Xiaodie also followed to join in the fun.
In the dark room filled with red light, Qu Bing was developing the pocket glass negatives at the operating table. The images of the small negatives soon appeared one by one, but they were obviously different from the silver plate photos taken before, because this was a real negative, which meant that the black and white colors were reversed from the positive.
For example, in the photo of Tang Yao and Shu Wu, the hair was very bright, but the cheeks and other skin parts were very dark. The three women frowned and asked Luo Chong one after another.
"Husband, is this photo taken badly? Why does it look so ugly?" Xiao Die couldn't help but question.
"No, it should be like this. This is called a negative film. It needs to be put on the enlarger and transferred to the photo paper. Then it will be positive. Although this technology cannot get a positive film at one time, its advantage is that it can copy the same photo infinitely, and it can also be enlarged and reduced."
Luo Chong explained to them while picking up a negative film that had been washed by Qubing, and then placed it on a film holder, and then inserted it into the photo enlarger next to it. He turned a knob on the side of the machine head and adjusted the angle of the mirror inside. The mirror quickly reflected the light of a calcium carbide lamp sealed in the machine head, and shone vertically downward through the negative film stuck on the machine head.
So, under the gaze of several people, this vertically installed projector projected the image of the negative film onto the glass operating table directly below, turning it into a pattern with a positive image, but at this time, a piece of ordinary paper was still placed to adjust the focus and find the size.
"See, isn't it a positive now?" Luo Chong said while demonstrating.
Qubing and Aofei's eyes were immediately attracted. "Chief, how do we enlarge it?"
"Isn't it the same as when you lengthen the lens to adjust the focal length? See the wheel on the side of the enlarger? Shake the handle on it to control the entire head to move up and down, and then change the size of the photo projected below." Luo Chong said as he shook the handle.
The photo of the Rat Witch holding the sundial began to enlarge on the operating table below. When Luo Chong raised the projector head, the photo began to shrink again.
"Wow, it turns out that it can be done this way. It's so convenient to be able to enlarge and reduce. In this way, we can make the size we want." Zhan Ying also said excitedly.
"Not only that, this thing can be copied many times. Bring me a piece of photo paper." While
Luo Chong was talking, he began to adjust the height of the head, enlarged the projected photo to just one-quarter the size of the photo paper, fixed the caliper below, and then blocked the light projected from the head with a plug plate. In the dark, he took the photo paper and placed it in the position pre-identified by the caliper, then pulled out the light shielding plate of the head and began to expose the photo paper.
After counting for a few seconds, he closed the camera head shading plate, moved the photographic paper again to start exposure, and repeated this method four times. Then Luo Chong handed the photographic paper to Qubing.
"Develop this paper the same way you would develop a photograph."
Qubing did as he was told and placed it in the developer. In just a dozen seconds, images began to emerge on the photographic paper. Four identical photos of the Rat Witch appeared on the same photographic paper at the same time. Except for the slight color differences caused by the slightly different exposure times, the four photos looked like they were made from the same mold.
Only then did they realize that the pocket film that Luo Chong mentioned could really be used to enlarge and reduce photos and to repeatedly copy photos.
Qubing was immediately excited, and he hurriedly begged Luo Chong.
"Chief, now that we have succeeded, why don't you tell us what this photographic paper is made of?"
