Who invented photography and when was it introduced to China?

As we all know, photography was invented by French L Daguerre. 1839 August 19 France announced to the world. L Daguerre's full name is Louis Jacques Mond Daguerre. Born in1787-died in 185 1 year.

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. ?

186 1 year, physicist Maxwell invented the world's first color photo.

Photography was introduced to China in the Qing Dynasty. Silverplate photography was introduced to China from France in 1837, and then to China from the west in a few years. The earliest camera was brought to China by Jules Etienne, a Frenchman who worked in China Customs.

The first photo in the world dates back to 193 years ago. During the first industrial revolution, European scientists improved their understanding of the imaging of photosensitive substances and objects through research. 1826, Nipps, a Frenchman who was interested in inventions since childhood, took the first surviving photo in human history on the basis of previous studies: the scenery outside the window was etched by sunlight.

It took Nipps eight hours to take this photo. In order to improve the exposure imaging time, he found the director Daguerre. Together, they improved their technology and finally released Daguerre Photography on 1839. This is the real beginning of photography technology in human history.

In the following 50 years, although photography technology has been evolving in shortening exposure time, wet photography and dry photography were born, but the whole set of photographic equipment is still very heavy and inconvenient to carry.

An article in China Photography describes the wet printing method that was popular in the middle of19th century. "Photographers must bring shading tents, chemicals, glass sheets, bulky brackets and a pot of water when they go out to shoot. The whole set of equipment is usually a whole carriage."
