Why did Germany and Japan take color photos when they signed the surrender ceremony in World War II, but the video was black and white after People's Republic of China (PRC) was founded four years later? Is China broke? It wasn't because China didn't have money at that time, it wasn't because there was no color photography technology and equipment, and it wasn't because there was no color video of founding ceremony at that time. But because of a small accident, this precious color video could not be saved.

1949 In September, the New Zheng Zhi Consultative Conference decided to declare the founding of the country on 10 in June, and China also notified the Soviet Union. The Soviet side immediately sent a news delegation headed by simonov (including a photography team) to founding ceremony.

When I was in founding ceremony, there were actually two photography teams shooting documentaries on the spot. One is a team of photographers from Northeast Film Studio, who are responsible for shooting black and white films. The other is the Soviet photography team, which is responsible for shooting rare color films at that time. Unexpectedly, when the Soviet photographer returned to Beijing Hotel, an indoor fire was caused by careless smoking, and all those color films were burned. Therefore, the founding ceremony documentary we see today is only a black-and-white shot taken by China people themselves.
