Automobile film photography competition

Film belongs to the category of hazardous waste. Some toxic chemicals will be added during film production, which will affect human health and natural environment. Everyone must pay attention when throwing this kind of garbage, and don't throw it around casually, so as not to cause harm to people and the environment.

Film, also called negative film, is an imaging device. At present, the widely used film is coated with silver halide on the basis of polyacrylate film, and it is very soft and easy to use when rolled into a whole roll. Film is generally composed of emulsion and anti-halo layer. The main components of photographic emulsion are silver halide and photographic gelatin, which are wastes that directly or potentially endanger human health or natural environment.

In fact, film is used in many fields of our lives, such as machinery, electronics, automobiles, architecture, daily necessities and so on. The well-known medical X-ray film is also used.

Film returns to photography market.

In June 2009, Kodak announced that it would stop producing Kodak Roman film. The progress of science and technology finally forced the film to withdraw from the historical stage. The progress of science and technology also makes it easier for us to get a memory that belongs to us, but it also becomes more and more cherished.

Although Kodak has undergone a difficult transformation, it has been reshaped into a company whose main business is to provide professional printing technology, but the original film business has shrunk to a niche market with less than 10%. However, this small and cold "old" business, with the recent retro movie craze among young people, has become popular again. The price of film has gone up several times, and the demand exceeds the supply. Kodak Film Factory has expanded its staff.

This movie studio has been running continuously for 7×24 hours. In the past few years, the output of 35 mm film has doubled, but it still cannot meet the demand.
