Color 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. The first color cinematography was by additive color systems such as the one patented by Edward Raymond Turner in 1899 and tested in 1902.〔http://www.bbc.co.uk/news/uk-england-19598445 Martin Scorsese on world's first colour film discovery BBC〕 A simplified additive system was successfully commercialized in 1909 as Kinemacolor. These early systems used black-and-white film to photograph and project two or more component images through different color filters. Around 1920, the first practical subtractive color processes were introduced. 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. 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. In 1935, Kodachrome was introduced, followed by Agfacolor in 1936. They were intended primarily for amateur home movies and "slides". 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. The few color films still being made in the 2010s are of this type. The first color negative films and corresponding print films were modified versions of these films. They were introduced around 1940 but only came into wide use for commercial motion picture production in the early 1950s. 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. 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. Fuji's products are compatible with ECN-2 and ECP-2. Film was the dominant form of cinematography until the 2010s, when it was largely replaced by digital cinematography.〔http://www.indiewire.com/article/as-studios-abandon-35-mm-film-small-theaters-struggle-to-transition-to-digital〕 ==Overview== 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. Light, shade, form and movement were captured, but not color. With color motion picture film, information about the color of the light at each image point is also captured. 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. Current color films do this with three layers of differently color-sensitive photographic emulsion coated on one strip of film base. Early processes used color filters to photograph the color components as completely separate images (e.g., three-strip Technicolor) or adjacent microscopic image fragments (e.g., Dufaycolor) in a one-layer black-and-white emulsion. Each photographed color component, initially just a colorless record of the luminous intensities in the part of the spectrum that it captured, is processed to produce a transparent dye image in the color complementary to the color of the light that it recorded. The superimposed dye images combine to synthesize the original colors by the subtractive color method. In some early color processes (e.g., Kinemacolor), the component images remained in black-and-white form and were projected through color filters to synthesize the original colors by the additive color method. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Color motion picture film」の詳細全文を読む スポンサード リンク
