Wei Yan tinkered with it for seven or eight days and actually managed to build a camera.
This camera uses the most primitive imaging technology, namely the daguerreotype.
The materials used in the daguerreotype process are relatively simple.
After cleaning and polishing the silver-plated copper plate, it is placed in an iodine solution to allow the iodine and silver to react. Then it is placed in a dark box for filming.
When exposed to light, the silver iodide synthesized on the photographic plate is reduced to silver, forming a shadow.
Then develop with mercury vapor and fix with hot saline solution.
Then wash and dry it, and you'll get a photo.
As for the convex lenses and apertures needed to make the camera obscura, they were a piece of cake for Wei Yan, who had long mastered the technology of lens making.
When Xiao Qingyin saw the camera that Wei Yan had brought, she couldn't wait to pull Yi Shuihan to stand in front of the camera so she could take a picture of him.
Wei Yan scratched his head, embarrassed, and said, "It seems that my camera can't take pictures of people. The exposure time is too long, and people disappear as soon as they move."
Xiao Qingyin: "..."
She almost forgot about that.
However, she quickly came up with a solution.
"Yi Wu, come here and apply acupressure to your master."
Once Yi Shuihan was immobilized, he couldn't move even if he wanted to.
Xiao Qingyin said to Wei Yan, "Alright, we can start filming now."
Wei Yan: "..."
He really hadn't thought of this method.
He originally thought that only people like Xiao Shu, who were lying down and unable to move, could have their portraits taken.
The shoot lasted for half an hour. After it was finished, Wei Yan took the photos to be developed and fixed, and then showed them to Xiao Qingyin.
Yi Shuihan looked astonished when his acupoints were located, and the photos taken naturally reflected that astonishment.
It's incredibly funny to watch.
Xiao Qingyue said helplessly, "I'll have someone frame the photo and put it on my desk later."
Yi Shuihan was amazed by the image on the bronze plate and pulled Xiao Qingyin's hand, wanting to take a picture with her.
The two then took a photo together.
Xiao Qingyin then asked him to recreate the "keeping a beauty in a golden house" scene, took a picture of him, and also captured many of his charming and innocent expressions.
Fu Weiyun and Yun Wanyin came over and saw this strange gadget, the camera, and took quite a few photos.
Xiao Qingyin has collected all of these photos.
She originally intended to make a record, but it turned out to be a precious memory.
Not content with just photographing everyone, she also went outside with Yi Shuihan to take street photos.
The streets were bustling with pedestrians, but after a long exposure, only empty streets remained.
Although it's a bit stiff, it accurately reflects the current street scene.
A hundred years from now, these will all be valuable historical materials.
Xiao Qingyin thought so.
Because waiting for the photos to be released was extremely boring, she set up her camera on the street and surrounded it with benches while she and Yi Shuihan sat down at a nearby tea stall to drink tea.
After Yi Shuihan became a fool, he became exceptionally impatient.
After drinking two cups of tea and eating a plate of snacks, he took Xiao Qingyin's hand and wanted to go to the street to see the excitement.
Just then, someone was performing acrobatics, so Xiao Qingyin went with him to watch.
Unexpectedly, there were too many people watching the acrobatics, and the two of them got separated in the crowd.
Xiao Qingyin pushed through the crowd, about to catch up with the idiot, but in the blink of an eye, he had vanished.
"Yi Wu!"
She quickly called for her bodyguards.
"Look for your master, he's gone."
Everyone started searching together.
I searched all the nearby streets and alleys, but couldn't find him.
Xiao Qingyin had a bad feeling.
That guy has probably been kidnapped.
They immediately split into two groups: one group went to intercept people at various city gates, and the other group went door-to-door to search for people.
Yi Shuihan was completely unaware that someone was looking for him.
He and his wife were standing together watching the acrobatics when they were suddenly bumped to the side by people pushing past them, and were immediately pulled into a building on the side of the street.
As soon as I entered, I saw people playing musical instruments, singing, drinking, and having fun. It was quite a lively scene.
He then thought of inviting his wife in to play.
But as soon as he turned around, an old woman came over and said to him, "Your wife is waiting for you over here."
He didn't believe it.
"My wife is clearly outside."
The old woman laughed and said, "Listen carefully?"
He listened intently and indeed heard his wife's voice coming from inside.
He then followed the old woman to the inner courtyard.
After they reached the door of a room, the old woman said to him, "Your wife is inside. Go in."
Yi Shuihan pushed open the door and entered.
The moment he stepped inside, a wave of heat hit him, catching him off guard. He took a breath and felt a little dizzy.
The old woman gave him a push, shoved him into the room, and said with a fawning smile, "Enjoy yourself."
Yi Shuihan stumbled and almost fell.
After standing still, they found that there were only seven big men in the house, and no wives.
Then he wanted to turn around and leave.
But they found the door was bolted shut.
The seven burly men surrounded him, all staring intently at him with murderous intent.
"stop."
He said unhappily.
"Don't come any closer."
These burly men, whose eyesight wasn't as sharp as his, didn't stop when they heard his words; instead, they quickened their pace.
Yi Shuihan frowned: "If you come any closer, I won't be polite."
"Hehe, my beauty, don't be so polite with your brother."
A burly man grinned maliciously.
They pounced on it like tigers pouncing on their prey.
Yi Shuihan had already given them a warning, but seeing that they wouldn't listen, he decided not to be polite to them.
He pressed the wrist mechanism, and the crossbow bolt flew straight towards the big man's shoulder.
The burly man cried out in pain and collapsed to the ground.
Hearing the shouts, the others glanced at him but still rushed towards Yi Shuihan.
