This is a list of color film processes known to have been created for photographing and exhibiting motion pictures in color since the first attempts were made in the late 1890s. It is limited to "natural color" processes, meaning processes in which the color is photographically recorded and reproduced rather than artificially added by hand ...
It is able to store a wider range of color values than sRGB. The Wide Gamut color space is an expanded version of the Adobe RGB color space, developed in 1998. As a comparison, the Adobe Wide Gamut RGB color space encompasses 77.6% of the visible colors specified by the Lab color space, whilst the standard Adobe RGB color space covers just 50.6%.
Prizma gave a demonstration of color motion pictures in 1917 that used an additive four-color process, using a disk of four filters acting on a single strip of panchromatic film in the camera. The colors were red, yellow, green, and blue, with overlapping wavelengths to prevent pulsating effects on the screen with vivid colors.
A color film is made up of many different layers that work together to create the color image. Color negative films provide three main color layers: the blue record, green record, and red record; each made up of two separate layers containing silver halide crystals and dye-couplers.
Kodachrome K135 20 Color Reversal film Kodachrome II – film for color slides; the 35 millimeter still photography format is shown above. Kodachrome was the first color film to be successfully mass-marketed that used a subtractive color method. Previous materials, such as Autochrome and Dufaycolor, had used the additive screenplate methods ...
The photographic reproduction of natural colour by means of a black-and-white photograph taken and viewed through a mosaic of tiny colour filters was an idea first patented and published by Louis Ducos du Hauron in the late 1860s, but the incomplete colour sensitivity of contemporary photographic materials made it impractical at that time.
It is the standard development process for all modern motion picture color print developing, including Fuji and other non-Kodak film manufacturers. All film stocks are specifically created for a particular development process, thus ECP-1 film could not be put into an ECP-2 development bath since the designs are incompatible.
As a bipack color process, the photographer loaded a standard camera with two film stocks: an orthochromatic strip dyed orange-red and a panchromatic strip behind it. The orthochromatic film stock recorded only blue and green, and its orange-red dye (analogous to a Wratten 23-A filter) filtered out everything but orange and red light to the panchromatic film stock.
