Were there black and white photos during the Qianlong period?
The first photo was taken in 1827, and Aisingiorro Hongli (171September 25th/year-1February 7th, 799) was the year of Qianlong. So there were no black and white photos in Qianlong period.
The world-recognized inventor of photography is Daguerre. Nipps, a photographer, has never been noticed by the public. He took the first photo in the world. At that time, there were many problems to be solved in the production of photography.
As early as Aristotle and China Mozi, people discovered the mystery of pinhole imaging, and this principle still applies to photography today. But the important reason that hindered photography at that time was that the method of saving images had not been discovered.
/kloc-around 0/826, Nipps entrusted Charles Chevalier, an optical instrument dealer, to make optical lenses for his camera box, and made the world's first camera.
This summer, he painted a mixture of ash and asphalt on a lead-tin alloy plate to make a photosensitive metal plate. Niepce put it in the camera, exposed it to the window in his attic for 8 hours, then washed away the unexposed white asphalt mixture hardened with lavender oil, exposing the dark black of the metal plate, and got the positive image of the scenery outside the window: pigeon cage on the left, warehouse roof in the middle, and a corner of another house on the right.
Due to long exposure, both sides left traces of sunlight. This is the first "out-of-the-window" photo recognized in the world and is currently kept in the French Museum. Niepce called his method "sunlight etching", which was more than ten years earlier than Daguerre photography.
He should be called the real inventor of photography, just because he didn't disclose his secret in time, so he missed the opportunity to enjoy the inventor's crown alone. ?
