There were no cameras during the Yongzheng period. Yongzheng died on October 8, 1735, and the earliest camera was invented in 1822.
The world's first camera was invented by the Frenchman Niséphore Niépce in 1826. Its appearance was a simple wooden box. It used the imaging principle of camera obscura to "photograph" The world's first permanent photo, which represents "the birth of photography."
In fact, this camera can only be regarded as a prototype of a camera and did not realize photosensitive imaging. It really made photo studios spring up like mushrooms after a rain. The year 1839, when Daguerre’s invention was made public, is also known as the birth year of photography.
Extended information:
The earliest camera structure is very simple, including only a camera obscura, lens and photosensitive material. Modern cameras are more complex, with lens, aperture, shutter, ranging, framing, metering, film transport, counting, self-timer, focus and zoom. System, modern camera is a complex product that combines optics, precision machinery, electronic technology and chemistry.
In 1550, Cardano of Italy placed the lenticular lens in the original pinhole position. , the image effect is brighter and clearer than that of the camera obscura. In 1558, Barbaro of Italy added an aperture to Cardano's device, which greatly improved the image clarity; in 1665, the German monk John Chapter designed and produced one. A small, portable single-lens reflex camera obscura. Because there was no photosensitive material at the time, this camera obscura could only be used for painting.
In 1822, Niépce of France made the world's first camera based on photosensitive materials. The first photo was not very clear and required eight hours of exposure. In 1826, he took another photo through a camera obscura on a tin plate coated with photosensitive asphalt. Goland invented the first all-metal camera, which was equipped with the world's first mathematically designed photographic lens with a maximum phase aperture of 1:3.4.
1845. In 1861, the German von Martens invented the world's first 150° panning camera. In 1849, David Brewster invented a stereoscopic camera and a dual-lens stereoscope. Maxwell invented the world's first color photo
