Chapter 790: The Revelation of Color Photos

Luo Chong looked at the stunned faces of the group of people across the table, and his evil taste was greatly satisfied. While they were still not aware of what was happening, he immediately revealed another big news.

"In fact, your photography technique has another major disadvantage, which is that the conditions are too restrictive. First of all, the camera is too large and inconvenient to move, not to mention carrying it with you. Secondly, you need a darkroom to develop photos. If you want to take photos in a place, you can't carry a darkroom with you everywhere, right? What if I ask you to go up the mountain to take photos? Do you still have to carry a darkroom up the mountain, or build a simple darkroom temporarily on the mountain? Is it troublesome?"

Qubing suddenly asked at this time, "But without a darkroom, there is no way to develop photos. The film solution will be useless after it dries up."

"This is the biggest problem. What if you can make dry negatives? If you use it with an enlarger, you can make a camera as small as a palm, and take it wherever you go.

Then you can make some ultra-small dry negatives in advance, put them in a box, and carry hundreds of negatives with you at a time. Put them in a palm-sized camera, go out and take pictures, and then take them back to the darkroom to develop them slowly after you come back. After they are developed, they can be copied and enlarged with an enlarger. You can copy as many copies of a photo as you want. Isn't this better?"

The people across the table continued to be stunned. Although this was just Luo Chong's idea, it did sound very tempting. Once this technology can be realized, the impact on human life will definitely be huge.

However, Luo Chong first led their thinking to the military.

"If these technologies can be realized, can we equip the scouts on the front line of the army with such a small camera, so that they can directly take pictures of the target when they are scouting the enemy, and then bring the negatives back to develop photos, so that the generals can directly see the situation on the front line while sitting in the barracks.

Or when we search for a person, we can copy thousands of copies of his photo, and then everyone will go to search with one. Do you think if we had this technology at the beginning of the year, Maodun would still be able to escape?"

Several people were almost speechless. What kind of brain did the leader have? How could he use everything in the military?

However, Ao Fei didn't care about these. He was not a soldier. As a researcher, what he wanted to know most was whether these ideas mentioned by Luo Chong could be realized.

"Chief, can the functions and effects you just mentioned be achieved with current technology?"

"Of course, but this thing will definitely take a few days to prepare. We will take pictures in the afternoon. When I am ready in two days, I will tell you how to enlarge the photos, how to make dry plate negatives, and how to copy them repeatedly." Luo Chong answered immediately.

Hearing Luo Chong's words, the people on the opposite side suddenly became excited. This might be the invention with the fastest technological improvement speed since it was born in their hands.

After dinner, they rested for another three hours. Luo Chong's two children had the habit of taking a nap. Qubing and his friends also took advantage of this gap to set up a temporary darkroom in Luo Chong's yard. It was not until more than three o'clock in the afternoon that the two little guys woke up. Luo Chong asked Xiaodie and Zhan Ying to take them to prepare for the family photo shoot. Because they knew that they were going to take photos today, Tang Yao did not go to school, but stayed at home to take some photos.

Three chairs were placed at the main entrance of Luo Chong's house, with the villa as the background behind them. Because there was no flash to fill in the light, they could only use natural light to shoot. Of course, the outdoor light conditions were better. If they took photos in the house, they could only use calcium carbide lamps to fill in the light.

Just when Qubing and others were making negatives in the darkroom, Ao Fei was fiddling with his camera in front of Luo Chong, first adjusting the angle, and then using frosted glass as a viewfinder to frame the picture.

Luo Chong was wearing a black and red formal gown and a gilded crown. He was sitting on a chair, holding his well-behaved daughter in a pink and white dress with a double bun on her head. She was licking a lollipop, her legs swaying. Xiao Die and Zhan Ying were sitting on either side of him in red and blue formal attire, with their heads covered with all kinds of dazzling jewelry. Little Luo Cheng was also dressed very delicately, with a black gauze crown on his head and a bright red silk robe. He was standing in front of Luo Chong, fiddling with the wooden sword hanging on his waist.

At this moment, Luo Chong suddenly asked Ao Fei, who was standing opposite him, a question.

"Ao Fei, what are the three primary colors of pigments?"

Ao Fei, who was adjusting the camera, was stunned. He didn't understand why the leader suddenly asked this question, but he answered immediately.

"To the leader, the three primary colors of paint are rose red, sky blue and goose yellow. By adding these three pigments, you can make various colors. If you mix them all, it will become black."

The Han tribe has used this method to make paint for several years. The basic knowledge of the three primary colors of pigments has long been popularized. As one of the top people in the research institute, Ao Fei naturally knows it.

"Yes, then you have been studying the decomposition of spectra by prisms for quite a while. Let me ask you again, what are the three primary colors of light?" Luo Chong continued to ask.

This is a new theory that their optical group has recently experimentally analyzed. As the leader of the optical group, Ao Fei is of course very clear about it, so he did not hesitate and answered it immediately.

"To reply to the leader, the three primary colors of light are red, indigo, and grass green. The three can also be combined to form various colors of light. If the three primary colors are combined in equal amounts, it will become white light."

Luo Chong nodded, but suddenly prompted, "Since the three primary colors can form various colors of light, you say, if you make filters of these three colors and put them in front of the lens, can you take color photos?"

With a bang, the frosted glass in Ao Fei's hand fell to the ground and shattered. He was stunned for a moment. Luo Chong's words seemed to be a thunderbolt in his mind, which made him stunned on the spot, and he was still muttering in his mouth.

"So that's it, so that's it, so color photos should be taken like this"

Luo Chong couldn't help but smile at his reaction. Researchers are like this, just like lunatics, always like to be startled.

"I just proposed this idea. You can go back and slowly experiment with how to do it. And I remind you that even if this method can take color photos, if you don't have color negatives, it is impossible to show the colors on the photos.

Go back and study it slowly, but I can promise you now that if you have developed color photography, I can upgrade your title by two levels."

"Thank you, chief. Ao Fei will definitely not disappoint you." Ao Fei immediately bowed and saluted. Qu

Bing also ran out in a hurry with the wet film he had just made, asking as he ran.

"Chief, what about me? What if I figure it out?"

"You are a soldier. Why are you competing with them? If you want to gain credit, go to the battlefield." Luo Chong retorted to him. This kid has made some inventions and has become more and more arrogant these days. He must be suppressed.

"Oh." Qu Bing pursed his lips in dissatisfaction, inserted the film in his hand into the camera, and then began to direct Luo Chong's family to adjust their postures, ready to take a family photo for them.
