Who invented the first camera and what did it look like?

Gaidar is the inventor of photography, not the inventor of the camera, the camera was produced on the basis of the painting camera obscura, which was first used by European painters, as for which one is the real camera, there is no way to verify, but this is probably what it looks like.

The first camera was invented by Daguerre in France in 1839.

It was invented in 1975.

After graduating with a master's degree in 1973, Steven Sasson joined Kodak as an engineer at the Applied Electronics Research Center. In 1974, he took on the task of inventing the "hand-held electronic camera". The following year, the first prototype was born in the laboratory, and he became the "father of the digital camera".

When the prototype was first shown to investors, they asked when it would become a consumer product, and I was surprised that it would be about 15 or 20 years before this product would enter the homes of ordinary consumers. ”

Sezanne was quite accurate in his judgment that the development of digital cameras was a long road, and in the late 1970s and early 80s, Kodak Laboratories produced more than 1,000 patents related to digital cameras.

It has laid the foundation for the architecture and development of digital cameras, so that digital cameras can move towards reality step by step. In 1989, Kodak finally launched the first commercialized digital camera.

On August 19, 1839, the French painter Daguet Maden announced his unknown invention of "Daguerre daguerreotype", and the world's first portable wooden box camera was born.

In 1841, the optician Vogeland invented the first all-metal camera. The camera is equipped with the world's first mathematically designed photographic lens with a maximum phase aperture of 1:.

In 1845, the German von Martens invented the world's first panning 150° machine. In 1849, David Bruuster invented the stereoscopic camera and the two-lens stereoscopic viewing glass. In 1861, physicist Maxwell invented the world's first color photo.

The world's first camera was invented in 1839. France's Daguerre made the first practical daguerreotype camera, which is composed of two wooden boxes, one wooden box is inserted into the other wooden box for focusing, and the lens cover is used as a shutter to remove dust, to control the ** time of up to 30 minutes of Hidden Meditation, which can shoot clear images.

The first was invented by Daguerre, and in 1839 Daguerre of France invented the first one.

Generally speaking, we all have to think carefully. Personally, the meaning of life to me is very important. Life, what happens when it happens, and what happens if it doesn't.

The so-called life, the key is how to write life. Turgenev said a philosophical phrase, do you want to be a happy person? May you first learn to endure hardship.

I hope you can also appreciate this Qiaosheng remark. This fact means a lot to me, and I believe it has some meaning to the world.

A box that does not sell well and transmits light, this is the camera machine. A camera is a photographic device that uses photosensitive film to capture a negative scene. Its invention has gone through a long time.

Let the world see what is there to be happy about in this tolerant state? It's interesting to fall in love, and the other party is pretending to be a nuisance. My sister just told me that he was out and that he had nothing to do, just to accompany his little brother.

In 1802, the Englishman Vichod first used the photosensitive effect of silver nitrate to apply silver nitrate to paper and make a photograph. In 1827, the Frenchman Nebbs sprinkled bitumen powder on tin or glass plates, which were topped with a layer of oil or wax to make them translucent. Under the sun, after a long period of exposure, it can leave a white shadow of the real thing, making a ** that will not disappear.

However, for each photograph of these, 6 to 8 hours in the sun is a complex process that is clearly not suitable for practical use.

By 1839, there had been new advances in photographic technology. A French scholar named Daguerre discovered a new photosensitive material by chance. While researching photographic techniques, Daguerre accidentally placed a silver spoon on a metal plate treated with iodine, and after a while, Daguerre discovered that the shadow of the silver spoon was actually printed on the plate.

He was taken aback by this phenomenon. So he specially polished the metal plate, coated it with iodine, and shot it with a lens, and sure enough, he captured a thin shadow. This success greatly boosted Daguerre's confidence.

Daguerre continued his march towards the final hurdle of breaking through photographic technology. Another fortuitous discovery helped him a lot. One day, Daguerre went to the medicine box to look for medicine, and suddenly saw that the image had become very clear on the negatives that had been exposed to light in the past.

What is the reason for this? In order to find the answer, he put a negative piece of Fu Yuan exposed to light in the medicine box every night, and the next morning, he took out a bottle of Duan Stool medicine at the same time as taking out the negative. He thought:

If an effective drug is taken out of the box and then put into the exposed negative, it is impossible to show it clearly.

But to Daguerre's surprise, when all the medicines in the box were removed, the negatives were still clearly visible. This surprised Daguerre. In order to find out the cause thoroughly, Daguerre turned the box over and over again, and finally found some small mercury beads in the box.

He immediately realized that the miracle must have been caused by mercury. After analysis, Daguerre concluded that the high temperature in the box caused the mercury to evaporate and affect the negative, making it appear well.

In order to confirm this judgment, Daguerre tested the exposed negatives in a darkroom with mercury vapor, and the desired results were achieved. In this way, Daguerre solves the problem of development, a key technology of photography. He then went on to solve the problem of fixing technology, thus completely solving the problem of photographic technology.

Daguerre's invention and today's photographic technology are essentially the same. Therefore, the invention of photographic technology should be attributed to Daguerre.

The first camera in China was invented by Zou Boqi.

Zou Boqi (1819-1869, a native of Nanhai, Guangdong), a physicist in the Qing Dynasty, was very good at astronomy, mathematics, optics, and geography. He made his own camera and filmed, and wrote "The Instrument of Photography" and "Grid Supplement", specializing in photography techniques and theoretical issues, he had independently manufactured China's first camera, only 4 years later than the West.

He also participated in the surveying and drawing of China's first map of China with latitude and longitude lines, and also surveyed and mapped the map of Guangdong, the map of Nanhai County, the map of Guangzhou City, the map of the corresponding towns of the Nanhai Division, and even the map of Xunfengzhou, where he was located.

Camera

A camera is a device that uses the principle of optical imaging to form an image and record the image with a negative, and is an optical instrument used for photography, which is composed of a lens, viewfinder, body and other components.

The most common cameras take images of visible light, but not all cameras require visible light (e.g., infrared cameras), and some do not even require a traditional light source (e.g., scanning tunneling microscope). In modern social life, many devices have the characteristics of cameras, such as radar, medical imaging equipment, astronomical observation equipment, etc.

In 1822, France's Nepps produced the world's first photographic material**, but the image was not very clear and required eight hours**. In 1826, he photographed a picture of the din substrate on a photosensitive bitumen with a camera obscura.

A tool that opens the door to the microcosm – the microscope (1665

The first microscope was made by an eyeglass maker named Jensen.

Invented around the year. This microscope is made with a concave mirror and a convex mirror to cover the cavern, and the level of production is still very low. Although Jensen was the first to invent the microscope, he did not realize the true value of the microscope.

Perhaps it is for this reason that Jensen's invention did not attract the attention of the world. Separation.

After many years, the microscope was successfully studied by the Dutchman Leeuwenhoek, and began to be used in scientific research experiments. Leeuwenhoek's invention of the microscope is also full of chance.

Leeuwenhoek.

Born in Delft, the Netherlands, he never received formal scientific training. But he was a man with a strong interest in novelties. Once, he heard from a friend that an optician, in Amsterdam, the largest city in the Netherlands, could polish a magnifying glass, and with a magnifying glass, he could see things that were not visible to the naked eye.

He was curious about this magical magnifying glass, but he couldn't afford it because it was too high. Since then, he has often been in and out of the optical shop, carefully observing the work of grinding lenses, and secretly learning the technique of grinding lenses.

Hard work pays off. 1665

years, Leeuwenhoek finally made a piece with a diameter only.

centimeter lens, and made a frame, this small lens is set on the shelf, and a copper plate is installed under the lens, and a small hole is drilled on it, so that the light shines from here and reflects what is observed. In this way, Leeuwenhoek's first microscope was successful. Thanks to his mastery of polishing high-magnification lenses, he was able to create a microscope with a magnification that surpassed any microscope available in the world at the time.

Leeuwenhoek didn't stop there, he continued to work on improving the microscope and further improving its performance in order to better observe and understand the mysterious microscopic world. To this end, he quit his job and devoted himself to the development of microscopes. A few years later, he finally made something that could magnify the object.

times the microscope.

One rainy day of the year, Leeuwenhoek scooped a cup of rain from the yard and observed it with a microscope. He noticed that there were many small, strangely shaped creatures wriggling in the droplets, and the number was staggering. In a single drop of rain, these small creatures were many times more numerous than the whole of the Netherlands at that time.

Later, Leeuwenhoek used a microscope to discover red blood cells and yeast. In this way, he became the world's first discoverer of the microbial world, being absorbed as a member of the Royal Society.

The invention of the microscope and the research work of Leeuwenhoek laid the foundation for the development of biology. Using microscopy, it was found that various infectious diseases are caused by specific bacteria. This has led to successful health check-ups against disease, vaccinations, and drug development.

Leeuwenhoek is said to be a man who kept his inventions secretive. Until now, microscopists have not been able to figure out how he managed to achieve such good results with that primitive tool.

The world's first camera was invented by Jules Jensen in 1874.

In 1874, Jules Janssen of France invented a camera in which he coiled photographic film around a toothed collapsing bucket belt disc and controlled by a pendulum mechanism that moved intermittently in a circular box while the oscillating mechanism drove the shutter to turn.

Whenever the film stops, the shutter opens**, allowing the mulberry to connect the camera to the telescope, which can shoot the speed of planetary motion in one second. Jean-san called it the camera gun, which is the ancestor of the modern cinema camera + Y6R.
