This is done by analyzing the visible spectrum of color into several regions (normally three, commonly referred to by their dominant colors: red, green and blue) and recording each region separately.Ĭurrent color films do this with three layers of differently color-sensitive photographic emulsion coated on one strip of film base. With color motion picture film, information about the color of the light at each image point is also captured. Light, shade, form and movement were captured, but not color. The first motion pictures were photographed using a simple homogeneous photographic emulsion that yielded a black-and-white image-that is, an image in shades of gray, ranging from black to white, corresponding to the luminous intensity of each point on the photographed subject.
6 Manufacturers of color film for motion picture use. Fuji's products are compatible with ECN-2 and ECP-2.įilm was the dominant form of cinematography until the 2010s, when it was largely replaced by digital cinematography. Later color films were standardized into two distinct processes: Eastman Color Negative 2 chemistry (camera negative stocks, duplicating interpositive and internegative stocks) and Eastman Color Positive 2 chemistry (positive prints for direct projection), usually abbreviated as ECN-2 and ECP-2. In the US, Eastman Kodak's Eastmancolor was the usual choice, but it was often re-branded with another trade name, such as "WarnerColor", by the studio or the film processor. They were introduced around 1940 but only came into wide use for commercial motion picture production in the early 1950s. The first color negative films and corresponding print films were modified versions of these films. The few color photographic films still being made in the 2020s are of this type. These were the first films of the "integral tripack" type, coated with three layers of differently color-sensitive emulsion, which is usually what is meant by the words "color film" as commonly used. They were intended primarily for amateur home movies and " slides". In 1935, Kodachrome was introduced, followed by Agfacolor in 1936. Before 1932, when three-strip Technicolor was introduced, commercialized subtractive processes used only two color components and could reproduce only a limited range of color. These also used black-and-white film to photograph multiple color-filtered source images, but the final product was a multicolored print that did not require special projection equipment. These early systems used black-and-white film to photograph and project two or more component images through different color filters.ĭuring 1930s the first practical subtractive color processes were introduced. A simplified additive system was successfully commercialized in 1909 as Kinemacolor. The first color cinematography was by additive color systems such as the one patented by Edward Raymond Turner in 1899 and tested in 1902. 
Still from test film made by Edward Turner in 1902Ĭolor motion picture film refers both to unexposed color photographic film in a format suitable for use in a motion picture camera, and to finished motion picture film, ready for use in a projector, which bears images in color.
