invention of a camera

 It is also known as a camera. It is used not only in commonly referred photography but also in fields such as press photography, commercial photography, architectural photography, or in a wide range of fields such as microscopy, roentgen photography, aerial photography, and astronomical photography. The origin is thought to be camera obscura (which means dark room in Latin). The prototype of the camera opscura is believed to have been used to project external landscapes or investigate solar eclipses through small holes in the roofs, walls, and doors of dark rooms. It has changed into a form that can be moved by several people, installed in a suitable place, so that the scenery can be observed from the inside, and then transformed into a small one that can be carried by one person, and developed into a shape close to the camera. Although Leonardo da Vinci invented the camera Obscure, the photographer, H.According to Gernshime's explanation, R. Bacon (1212-9412) of the UK not only knew the principle of camera obscura, but also observed Japanese food and scenery with it. However, there is also a record that the principle was discovered 20 years before bacon. Later than Leonardo da Vinci, the Italian physicist G.d.Porta (1535?~1615) recommends using the camera opscura as a tool for painting in his 1558 book "Magia naturalis." This was a well-known book at the time, and Leonardo da Vinci's note had been buried for about three centuries after his death, so there was a time when Porta was considered the inventor of the Camera Obscura. Meanwhile, Italian physicist G. Cardano wrote in 1550 that inserting a lens into a hole in the camera obscura would give a brighter image, and that the Venetian aristocrat D.Barbalo announced the effects of aperture in 1567. Looking at the connection between camera obscura and camera, the portable camera opscura presented by Wurtzburg monk J. Chan in 1685 is seen as the prototype of future box cameras or reflex cameras. The portable camera opscula was mainly used as a painting tool, and it was T. Wedgwood of England who conceived the idea of making images using the camera opscula, and the experiment was conducted around 1802 but failed. Unlike the camera opscura, the daguerreotype camera is the purpose of fixing the image from the beginning, that is, the camera for taking pictures. It has two wooden boxes overlapping and allows you to adjust the focus by pushing a dark slide from the back into a box with a lens in front of it. As for the lens, Chouvalier's Colourless Lens, which is said to have been modified by French Chouvalier for photography, were used, and the brightness was F14, which was not a complete lens. The camera went on the market in Paris in 1839. Meanwhile, according to Gernshime, British optical mechanic F. West advertised the sale of popular cameras two months before the daguerreotype camera was released, a calotype invented by W.H.F. Tolbert. The lens of the Daguerreotype camera was not performing well at the time of its release, so the demand for a brighter and sharper lens increased, so Vin's Petzbal designed an F 3.4 lens, and a forktrendel's metal camera with this lens was sold in 1841. Around 1850, cameras using folding sticks or cloth bodies were released. In addition, a two-eye stereoscopic camera (stereo camera) was also produced around this time. And the Collodion Act of 1851 was F.S.It was announced by Archer. The wet plate method was more convenient for photographing than the daguerreotype and the calotype, but there is a disadvantage that the photographing must be completed when the photosensitive film is wet. Therefore, studies have been conducted to prevent the wet plate from drying, and since 1856, a collodion plate in Norris, England, which covers the wet plate membrane with a solution such as Arabic rubber or gelatin or casein and dries it, has been commercially available. However, in 1871, Murdox of England announced a keyboard made by silver bromide, making it easier to handle cameras. As the dry plate became common, the sensitivity was higher than that of the wet plate, so it became impossible to expose it with a lens cap like in the wet plate era, and a drop shutter (gilitin shutter) installed in front of the lens was devised. Then, a folding hand camera came out, and a shutter was also operated at high speed. In the next 10 years, a changing box with several keyboards and a magazine camera with several keyboards inside the camera that can be replaced by a new one when photographed. Reflex cameras, on the other hand, were designed in 1861 to remove mirrors with handles only while T.Satten adopted the Camera Obscura Principle, as well as two or three patents and products, but later became the basis for numerous large 1-anliflexes such as Sophoflex, Solentonflex, and Graflex. This camera was introduced in 1898. A paper roll film was released by J. Eastman in 1884, and a Kodak camera using the roll film was manufactured and released in 1888. It is a simple box camera, but it succeeded in popularizing photos as the famous phrase, "Press the button, we'll take care of the rest." Subsequently, a nitrocellulose-based film was completed in 1889, and a pocket kodak using a folding roll film was released in 1898. In the 1900s, the products that are the basis of today's cameras were introduced, and the first was the German O in 1925.It is a Leica that uses 35mm film designed by Barnak. The original work was completed in 1914, but the announcement was delayed due to World War I, and after that, Leica has been released up to the current M6 model. The other is Raleiflex by Frange Heideke Co., Ltd., which was released in 1929. It is a model that opened the era of 2-anliplex, but only a small amount is currently produced. In addition, Chase Icon's spring camera group also formed an era, and these cameras laid the foundation for the current small cameras. And although they are not as common as these cameras, the Ermanox with F2 lenses was released in 1924. Until World War II, the 35mm camera group, which was the peak of Leica Contacts (Chiseicon Company), Lolai and numerous 2-anliflex, and the spring camera group were the main models of cameras. However, after the war, 35mm 1-anliflex and EE cameras that adopted Pentaprim appeared, and Kodak's instrumental camera group and auto focus (autofocus) cameras were developed again. In addition, a digital camera has recently been developed that can take and store photos without films.
