This paper briefly discusses the filtering principle of black-and-white photographic filter. What kind of color filter should be used for black-and-white photographic film to shoot blue sky and white clouds? The filter plays the role of passing, limiting and preventing all kinds of light. There is too much color luminous flux and too much film sensitivity, and the photos here are bright in tone. Or conversely, Dallas to the audience corrected the color of the original scene due to the passage and absorption of the filter, thus obtaining the effect of white, gray and black.
