Cold knowledge sharing in photography: Who took the first photo in human history?

The man who took the first photo in human history was called Nipsey, a Frenchman. He found that there was a kind of asphalt that would harden when it was irradiated by the sun. Asphalt is a dark brown complex mixture and a high viscosity organic liquid.

Joseph Nipps, who took the first photo in the world.

Asphalt will harden after being irradiated by the sun, and the part that has not hardened can be dissolved with some special solvents. This function is very interesting. At first, he copied prints in this way. Copying printmaking is to paint transparent pigment on the back of the painting to make the white paper transparent. He painted the painting with asphalt and dried it in the sun. The asphalt under the white part of the picture hardens gradually after drying, and the black part does not harden, then the unhardened part is dissolved with solvent, and the rest can be used for printing.

Later, Nepps thought, "Can I try the same method and put the real world scenery into this print?" He thought of it and did it.

It didn't go well at first and the color was unstable. Slowly, he groped for the experience, and then at 1826, he took the first photo in human history. You can vaguely see the house outside his attic in the photo.

However, Niepce's method cannot be used on a large scale. Because asphalt dries too slowly. Do you know that?/You know what? Do you know that?/You know what? In order to shoot the scene outside the attic window, it took eight hours to bask in tar.

Therefore, Niepce hopes to continue to optimize its technology. At this time, some people are paying attention to this method of recording images with light. These people found Niepce and wanted to cooperate with him. Nieps' final partner is our protagonist today. His name is Daguerre.

Daguerre is holding the flag of Nipps.

It's really bad luck to say this Niepce. Taking the first photo in human history, about six or seven years later, suddenly one day, he died of a stroke.

This sudden change suddenly pushed Daguerre to everyone's attention. Compared with Neptzer, Daguerre is very different. Niepce is a printer. The core purpose of all this is to simplify the printing process and make printing easier. Daguerre is a stage designer. In stage design, we often need to draw some deep streets, buildings and buildings. So his core purpose is to make stage design and painting easier. The reason why we want to cooperate with Niepce is that he thinks Niepce's method may be a good quick drawing skill.

Say Daguerre this person, really fierce. He used some existing experience and materials left by Nippzer to continue to improve his photography method, and finally perfected his photography method six years after Nippzer's death. He announced the success of the photography method he invented. Soon, the French Academy of Sciences also confirmed his invention. Although Daguerre didn't take the first photograph in the world, he became the inventor of photography.

Daguerre photography requires silver, iodine, mercury and salt. The production process is also very complicated. But at least, people can directly preserve the scenery they see in this way. However, the images obtained by Daguerre photography can't be developed through negatives or printed with manuscripts as we do now. The image taken by this method is directly printed on the copper plate as the bottom plate, so we must look at it from a certain angle.

In addition to these achievements, Daguerre also set a record. He took the first picture of a man in human history. Because the photography technology at that time required a long exposure time, even Daguerre photography required as much as 10 minutes. A person must stay still for a long time before his image can be preserved. Therefore, when Daguerre was filming the streets of Paris, he left his image because a person was receiving shoeshine service for a long time.

At that time, in order to protect the interests of inventors, a patent system had been established. If you can prove that you invented something independently, you can apply for a patent for it, and anyone who wants to do anything with your product or method will have to pay you in the future. This is actually to protect the enthusiasm of inventors.

Daguerre is not stupid. After he invented Daguerre photography, he also applied for a patent for this technology. However, the French government can't do this at first glance. Because this technology is very good, since it is a good technology, it should be used by more people. Besides, the French have invented such a good technology, and the French government has light on its face. So, the French government paid for Daguerre's photography and announced the cancellation of the patent, so that everyone can use it. So, if you have a good patent, you must remember to apply to a colleague in the legal department! They also prepared a generous return for everyone.

However, you should know that human science and technology are always moving forward. Just two years after the French government lifted Daguerre's photography patent 12, a new photography method was invented, which not only has better effect, but also has negative film, which can be used to copy photos indefinitely. So Daguerre's photography soon declined and became an exhibit in the museum for everyone to enjoy.
