When was the first camera invented?

a light-tight box, and this is the camera. A camera is a photographic equipment that is photographed with photographic film against the scenery. Its invention has gone through a long time. The study of light and image in China has a very long history. As early as more than 4 years BC, the book Mo Jing in China recorded in detail the straight-line advance of light, the reflection of light, and the imaging phenomena of plane mirror, concave mirror and convex mirror. In the Song Dynasty, the principle of "small hole imaging box" was also described in detail in Shen Kuo's book "Mengxi Bitan" (131-195). During the Renaissance in the 16th century, there appeared an "imaging camera box" for painting in Europe. On August 19th, 1839, the French painter Daguerre announced his invention of daguerreotype photography, which gave birth to the first portable wooden box camera in the world. In 1841, the optician Vogeland invented the first all-metal camera. The camera is equipped with the world's first photographic lens designed by mathematical calculation with a maximum phase aperture of 1: 3.4. In 1845, German von Martens invented the world's first 15-degree turning point. In 1849, Davie-Blue Scott invented a stereo camera and a two-lens stereo viewing mirror. In 1861, physicist Maxwell invented the world's first color photograph. In 1866, German chemist Schott and optical scientist Aju invented barium crown optical glass in Zeiss Company, which produced positive photographic lens, which made the design and manufacture of photographic lens develop rapidly. In 1888, Kodak Company of the United States produced a new type of photosensitive material-soft and windable "film". This is a leap in photosensitive materials. In the same year, Kodak invented the world's first portable square box camera with film. In 196, American George hillas used the flash for the first time. In 1913, German oskar barnack developed the world's first 135 camera. From 1839 to 1924, in the first stage of the development of this camera, some novel button-shaped and pistol-shaped cameras also appeared. From 1925 to 1938, it was the second stage of camera development. During this period, German companies such as Leeds, Lorelei and Zeiss developed and produced dual-lens and single-lens reflective cameras with small volume and aluminum alloy body. At this stage, the performance of the camera is gradually improved and perfected, optical viewfinder, range finder and self-timer are widely used, and the adjustment range of mechanical shutter is constantly expanding. The camera manufacturing industry began to mass-produce cameras, and camera manufacturers all over the world copied Leica and Lorefley cameras one after another. The sensitivity, resolution and tolerance of black-and-white photographic film are constantly improving; Color photographic films began to be popularized, so that the photography team expanded rapidly and became professional. The third stage of camera development since 1939. In the first half of this stage, before the 196s, the quality of black-and-white and color films was further improved, and the optical industry made new optical glasses containing rare elements, such as lanthanum, titanium and cadmium. Therefore, the aberration of the photographic lens is corrected better, and the lens develops rapidly in the direction of large aperture and various focal lengths. Therefore, there are many kinds of photographic lenses, such as zoom, emblem distance, catadioptric and wide angle. Single-layer coating of lens has been widely popularized. There are some structures in the camera, such as automatic reset of counter, automatic reset of mirror, semi-automatic and full-automatic contraction of aperture. The quality and output of cameras began to develop rapidly. From the early 196 s to the present, it is the late stage of the third stage. During this period, Japan's Xiaoxiliu Photography Company produced the world's first self-supporting focusing camera-Konica C35A 135 camera, and then Japan produced the world's first double-priority automatic exposure camera-Minolta XDG 135 single-lens reflex camera. It is a precedent that a camera has multiple exposure functions. During this period, the theory of optical transfer function entered the field of optical design, and a photographic lens with high imaging quality, good color reproduction, large aperture and low distortion appeared. At the same time, the lens has developed into a series, from fisheye lens with a focal length of several millimeters to super telephoto lens with a focal length of 2 meters, and there are photographic lenses such as perspective adjustment, zoom badge distance and night vision. Electronic technology has gradually penetrated into the camera, and a variety of photometry, high-precision electronic mirror shutter, electronic focal plane shutter and easy-to-control electronic self-timer have appeared one after another. Various functions, such as exposure compensation, memory storage, multi-recording function, electric winding, automatic focusing and so on, have been applied more and more beautifully, and the high degree of automation, miniaturization and portability have reached an unprecedented height. With the development of high technology, all kinds of new cameras for quality evaluation are constantly coming out, thus providing excellent equipment for the creation of photographic art.
