Did you have a camera in Qianlong period?

As early as16th century, artists used black boxes to record light and shadow. This kind of early photographic equipment can't take pictures. It just uses a hole in the wall of a dark room to project the scenery outside onto a plane. In fact, the whole room constitutes a pinhole camera. The literal meaning of the English version of the photo cassette is "darkroom".

The first photograph in history was taken on asphalt in 1826 by a Frenchman, joseph Nicephore Niepce (1765- 1833), but he died before the technology was finally perfected. His partner, the French painter Louis Jacques Manda Daguerre (1789- 185 1), invented the silver plate photography method based on his achievements, and in August 1839, the French government announced that he had obtained the photography patent. Today's Polaroid cameras still use a photographic method similar to the silver plate method. As another important founder, William Henry Fox Talbot, an Englishman (1800- 1877) published "Carlo Photography" in 184 1 year, and made a negative that can be copied many times, which laid the foundation for the photography technology of modern photography.

19 14 years, Oscar Barnack, the designer of the German "Leeds" microscope workshop, tried to make a double-size (24×36mm；; Model 135) camera (film specification is 18x24 mm), and Leica camera (Leica) is sold at 1924. 135 became the most popular film format in the future, which greatly reduced the size of the camera and made the mainstream of photography turn to documentary photography, which was quickly accepted by the public.

The Qianlong period was 17 1 1 to 1799, and there should be no cameras at that time.
