What does the flag of Dargay mean?

1. Dalgaiqi means: Dalgai photography is also called "silver photography". Originated by Daguerre, a Frenchman.

On a website, there is a very popular photography art exhibition module called Daguerre's Flag. This module is actually to commemorate a great artist, the pioneer of photography-Daguerre.

1839 1 month One day, a group of cows from the French Academy of Science and Art came to an old man's workshop. Every visitor is curious. They want to see Daguerre's upcoming tricks.

Daguerre was holding a copper coin carefully. The surface of the copper plate is coated with a thin layer of silver. He put the whole thing in a pot soaked in iodine solution, took it out and exposed it for 30 minutes. Next, he transferred the copper coins to the cassette and took some still lives on the table in the black box. This process also took about 30 minutes.

After that, he slowly covered the copper plate with mercury vapor at 75℃, and soon the silver and mercury merged. After the last salt water is fixed, it is finally the moment to witness the miracle. A picture gradually formed on the copper plate, just a still life!

Although this picture can only be seen from a specific angle and can only be maintained by sealing the glass box, it is still an epoch-making breakthrough. Later, film photography developed through the research of several generations of photographers.

Secondly, the name of Daguerre Flag is an affirmation of Daguerre's contribution, especially his achievements in photography technology, which has greatly changed human life.

Daguerre made a lot of efforts to invent usable cameras when he was young, but he still failed. It was not until he met Joseph Nissefer Niepce at 1827 that Nepes tried to invent the camera and succeeded. Two years later, the two began to cooperate and became partners with the same interests.
