The Birth of Photography and Its Significance

Before 400 BC, Mozi recorded pinhole imaging in Mo Jing. /kloc-in the 0/3rd century, an image black box made by pinhole imaging principle appeared in Europe. People walked into the black box to watch images or paint landscapes. 1550, the Italian cardano put the lenticular lens in the original pinhole position, and the imaging effect is brighter and clearer than the black box; 1558, the Italian Barbaro added an aperture to the device in cardano, which greatly improved the imaging clarity. 1665, John Zhang, a German monk, designed and made a small portable single-lens reflex camera box, which could only be used for painting because there was no photosensitive material at that time. 1822, the Frenchman Niepce made the world's first photo on the photosensitive material, but the image was not clear and needed eight hours of exposure.

Camera (20 photos) 1826, he took another photo on the tin substrate coated with photosensitive asphalt through the camera box. 1839, Daguerre made the first practical silver camera, which consisted of two wooden cases. One wooden box is inserted into another to focus, and the lens cover is used as a shutter to control the exposure time for up to 30 minutes, so that a clear image can be taken. 184 1 year, optician Vogeland invented the first all-metal camera. The camera is equipped with the world's first photographic lens with the maximum phase aperture of 1: 3.4 designed by mathematical calculation. 1845, German von Martens invented the world's first 150 turning point. 1849, Davie-Blue Scott invented a stereo camera and a two-lens stereo observation mirror. 186 1 year, physicist Maxwell invented the world's first color photo. 1860, Sutton, England designed the first single-lens reflex camera with a rotatable viewfinder. 1862, Detrie, a Frenchman, stacked two cameras together, one for taking pictures and the other for taking pictures, forming the prototype of a dual-lens camera. 1880, Baker of England made a double-lens reflex camera. 1866, German chemist Short and optical scientist Arjun invented barium crown optical glass in Zeiss Company and produced positive photographic lens, which made the design and manufacture of photographic lens develop rapidly. 1888 Kodak company 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. With the development of photosensitive materials, dry plates coated with silver bromide photosensitive materials appeared in 187 1 year, and nitrocellulose (road camera) appeared in 1884.
