What material was the film made of when it was first invented?
It is produced in a closed, completely black and ultra-clean workshop. Kodak and Fuji are the best. Le Kai, China has 16MM black and white film. Germany also has Akefa. Raw materials include silver halide, gelatin, etc. The most important factor affecting the stability is the quality of gelatin. For example, Kodak was built in Australia, because there are many cattle and sheep there, and animal bones are the main raw materials for extracting gelatin. Therefore, Kodak's performance is relatively stable.
