When was the camera invented?

That thing, I know what's the use.

The camera was built in 1839.

France's Daguerre made the first practical daguerreotype camera, which consisted of two wooden boxes, one wooden box was inserted into the other wooden box for focusing, and the lens cover was used as a shutter to control the ** time of up to 30 minutes, which could shoot clear images.

The camera camera obscura, which began to take shape in the 15th century, was used as an aid by artists for painting, and by 1550, Cardano of Italy placed a double convex lens on the pinhole of the camera obscura, and the image was brighter and clearer than that of the camera obscura.

The origin of the camera principle is much earlier, about 2,4500 years ago.

Chinese scholar Mo Zhai (Mozi) and his students did the world's first experiment on the inverted image of small holes, explained the reason for the inverted image of small holes, and pointed out the nature of the linear progression of light. This is the first scientific explanation of the linear propagation of light.

1. The camera was invented in 1839.

Daguerre, France.

The first practical silver plate camera was manufactured. The basic idea is to put a piece with silver iodide on the surface.

of the copper plate**, and then count the dust with mercury cracks.

It is steamed with a steam and then fixed with a common salt solution to form a permanent image.

3. Later, Daguerre used this method to build the world's first rampant camera. At the same time, Daguerre photography was the world's first successful method of photography.

In 1839, the French painter Daguerre made the world's first camera with his own invention of negative and developing techniques (daguerreotype), combined with the fixing technique invented by Haschelf and the printing paper invented by Vicaud.

Extended Material: The Origin of the First Camera

From 1829 onwards, Daguerre and Nieps collaborated to develop and refine the photographic method invented by Nieps. The two of them were like-minded and like brothers, and began a four-year cooperation. As they collaborated, they encouraged and inspired each other, and the new photographic method matured day by day.

In 1837, Daguerre succeeded in inventing a practical form of photography called Daguerre photography (daguerreotype).

Daguerre's photographic method was the world's first successful photographic method. The basic idea is to make a permanent image by taking a copper plate with silver iodide on the surface**, then steaming it with mercury vapor and fixing it with a common table salt solution. Later, Daguerre made the world's first camera based on this method.

His camera is basically similar to the one we use today, consisting of a lens, aperture, shutter, viewfinder, and camera obscura. The lens is an important part of the camera, and it is through it that the scenery is formed into an image. It consists of lenses of different properties and shapes, and the Daguerre camera has only one focal length, which is f=75mm.

Aperture is a device installed in the camera lens to adjust the intensity of light transmission, and cameras at that time had three apertures; A shutter is a device used to regulate how much light enters the lens; The viewfinder determines the range of the shot**; A camera obscura is a light-tight box that is used to hold film. Daguerre's ingenious design is still in use today.
