Extended data
The main purpose of color negative film is to print and play color photos. This is an extremely wide range of uses. Whether stored in a personal photo album or exhibited at a film festival, color photos are easy to watch directly, unlike color reversal films that require a slide projector and a screen.
Color negative can also be used to make color slides. However, it is necessary to purchase color positive films separately for reproduction, and the process is complicated, so the quality of the slides produced is not as good as that of color reverse films.
The exposure latitude of color negative film is greater than that of color reverse film; The color temperature of light source is not as strict as that of color reversal film, so color negative film is easier to shoot than color reversal film.
