Extended data

Color positive is used to print color projection copies (movies, slides). Features are: large contrast, low haze, high clarity and low sensitivity (and slides and actual effects are mirror images). ?

There are color and black and white, and inversion is actually a color inversion film, which is often used in still life photography. It makes sense to call it a reversal film: the first stage develops to form a negative image, and then uses color dyes to form a positive image. Reverse film is a kind of photosensitive film which can directly obtain positive image after reverse development.

Black-and-white reversal film can directly obtain the transparent film of the dark image consistent with the main body; The color reversal film can directly obtain the transparent film with the same color as the subject, and the color is true and bright, but the tolerance is small. Reverse film is widely used in printing plate making or making slides because of its high-quality positive effect. Professional photographers mostly use color reversal films when taking advertising photos.
