What do you mean by color negative and positive?

The negative is an image obtained after exposure and development, with the brightness opposite to that of the subject, and the color is the complementary color of the subject. It needs to be printed on a photo to be restored to a positive film. To put it simply, after the film we shot is developed, the image we see is an image with reversed color, and then it becomes an image with the same color as the scene we shot by zooming in or zooming in. Color film, the color on the film is only a supplement to the actual color of the scene, such as negative film, whether black and white or color, is the most commonly used film for photography. The negatives that we usually take pictures with ordinary cameras are negatives. Positive film is the general name of photographic film used to print photos, slides and film copies. It can print the negative film on the negative film into a positive film, so that the brightness or color of the image is the same as that of the subject. The sensitivity of black-and-white positive film is limited to purple-blue light, and the sensitivity of color positive film is weaker than that of color negative film, so positive film is rarely used in photography. After the negative film taken by the film camera is developed and edited, several copy tapes (the original film is very precious) are copied first, and then corrected with the positive film, and then it can be shown in the cinema. The feature film became a reverse film.
