A special black-and-white Separation Positive Film is also provided and this is intended for use in preparing three separation positives from the Colour Negative. (1973): ‘Blazing Technicolor,’ ‘Stunning Trucolor,’ and ‘Shocking Eastmancolor.’ In: Tom Shales et al. In: Karl-Dietmar Möller-Nass, Hasko Schneider and Hans J. These dyes and pigments are called the subtractive primaries, and they control the amounts of blue, green and red light in a mixture by absorbing or subtracting from white light the amounts of blue, green and red not required.

The oxidized developing agent combines with the colour forming coupler to create a dye of appropriate colour, the concentration of which is proportional to the amount of silver in the image. An Introduction to the Theories and Practices of Colour. Three types of Eastman Colour Film are manufactured.For this a special developing agent is used in conjunction with a second compound known as the colourforming coupler.Photographic development is a process of chemical reduction brought about by the developing agent, which is oxidized in proportion to the amount of silver formed.Three colour-forming couplers provide the appropriate dyes and are incorporated in the relevant emulsion layers.” (Craig, G. (1953): Eastman Colour Films for Professional Motion Picture Work. 146-158.) Batistová, Anna (2013): Glorious Agfacolor, Breathtaking Totalvision and Monophonic Sound. In: Simon Brown, Sarah Street and Liz Watkins (eds.): Color and the Moving Image. The separation positives form an intermediate link with the Colour Negative when making a Colour Internegative, so that their function is similar to that of a master positive in a black-and-white system. “Eastman Colour Films For Professional Motion Picture Work G. The photographs may be recorded on three separate films, as in the Technicolor camera, or on a single normal picture negative film, as in the successive frame method used for animation work. This can be done, either by taking three separate photographs through blue, green and red filters on normal panchromatic emulsions, or by using emulsions with colour sensitivities localized as far as possible to the appropriate spectral bands.

In modern processes of colour photography a technique has been established by which colours are analyzed in accordance with their reflectances within the three broad spectral regions, blue, green and red.

“The Eastman Colour Films are multilayer films of the type in which the layers are not separated after exposure. Yet another system is one in which a multilayer film is employed, with the emulsions coated one above the other on a single support.

Films of this class are known as Multilayer, Monopack or Integral Tripack. If the three layers can be separated after exposure then black and white images may be used — Multilayer Stripping Film is an example of this technique.

The silver image is removed at a later stage of the process.

Three colour-forming couplers provide the appropriate dyes and are incorporated in the relevant emulsion layers.

The coloured images in Eastman Colour Films are produced by a method known as dye-coupling development. Films of this class are known as Multilayer, Monopack or Integral Tripack.
