What do you mean by positive film, negative film, negative film and negative film?

Negative film is our most common kind, such as Kodak 100, Kodak Max, Fuji Superia 100. After development, the color of the film is opposite to the color of the real scene, that is to say, the black presented on the film is actually white in reality, which is opposite to the real color. It needs to be developed through C4 1 to realize the color inversion.

Reverse films, such as RVP Fuji, RDP, RHP, Kodak 100 VS, 100 g, that is, the color of the image presented on the film after shooting and developing is the same as the real image. To put it bluntly, the white color on the film is also white, black is black, and red is also red. Think back to when we were at school.

A positive film is not a reverse film, they are completely different, and a positive film cannot be used for shooting. Film shooting uses negative film, because the color of the developed film is opposite to the real scene, it is necessary to use positive film and negative film for overlapping exposure, and the developed film is used for projection. Because feature films are rarely used, there is no sales in the market.

The most commonly used film at home, that is, the most common film on the market, is the negative.
