The reason why color film can take color photos

The reason why color film can take color photos is that in the early days, color photographic film was painted by photographers on black and white photos by hand, and the color tone was often not in line with the actual situation, and it was labor-consuming and time-consuming. Now, there are more and more tones in photos, and the colors of photos can no longer meet people's requirements for tones. From 65438 to 0928, American photographers developed a soft lens with soft colors. However, when shooting, it is necessary to install three kinds of artificially drawn color filters on the lens, which is expensive to manufacture and the tone effect is not ideal. So the color effect of this lens is not ideal. Once, two American boys, Wanis and Gao Dukis, aged 65,438+06, enjoyed the color short film Navy and filmed it with a filter. They deeply regret that the colors in the short film are not realistic enough. After three years of unremitting efforts, they finally developed the world's first two-color photosensitive color film. After that, they further divided the photosensitive film into five layers, consisting of the first two layers of medicine film. In this way, the color of photographic works can be truly developed.
