Film that records an image with reversed tones and colors. Light areas appear dark, and each color appears as its complementary color, so red looks cyan, for example. When the negative is printed or scanned, the tones and colors are reversed again and look natural.
Color negatives have an orange base, called the orange mask. It corrects for flaws in the film's dyes and improves color accuracy in the print. Most color negative film is developed in the C-41 process. The opposite type is color reversal film, which gives a positive slide.
