What is a Barbie movie?

Barbie movie is a kind of color movie.

Early photographers colored black-and-white photos by hand, and the color tone was often not in line with the actual situation, which was labor-consuming and time-consuming. 1928, American photographers developed 16mm color film, but when taking pictures, three kinds of filters of red, green and blue need to be painted on the mirror manually, which leads to high production cost and unsatisfactory tone effect.

Once, two American boys, Wannis and Gao Dukis, aged 65,438+06, watched a set of color short films "Navy" shot with filters, deeply regretting that the colors in the films were not realistic enough, and determined to improve the color photography technology. The two partners have the same interest in music, so they use their spare time to study music theory and explore color photography. Five years later, both of them became young musicians, and at the same time, the research on color photography also made some progress. At that time, German scientists had successfully formulated the emulsion. They used this achievement to divide the emulsion into three layers, which are sensitive to red, green and blue respectively. 1930, they formally cooperated with Eastman Kodak company. After three years of unremitting efforts, they finally developed the world's first two-color photographic color film.

Later, they further divided the photosensitive film from the first two layers into five layers. In this way, you can print out the photos and print them truthfully.
