Eastmancolor

From Wikipedia, the free encyclopedia

Eastmancoloris a trade name used byEastman Kodakfor a number of related film and processing technologies associated with color motion picture production and referring to George Eastman, founder of Kodak.

Eastmancolor, introduced in 1950, was one of the first widely successful "single-strip colour" processes, and eventually displaced the more cumbersomeTechnicolor.Eastmancolor was known by a variety of names, such asDeLuxe Color,Warnercolor,Metrocolor,Pathécolor,Columbiacolor, and others.[1][2][3]

Eastman Color Negative

[edit]

Eastman Color Negative (ECN) is aphotographic processingsystem created byKodakin the 1950s for the development of monopackcolor negative motion picturefilm stock.It is part of the Eastmancolor family of products sold by Eastman Kodak.

The original process, known as ECN-1, was used from the mid to late-1950s to the early to mid-1970s, and involved development at approximately 25 °C for around 7–9 minutes. Later research enabled faster development and moreenvironmentally friendlyfilm and process (and thus quickerphoto labturnaround time).

This process allowed a higher development temperature of 41.1 °C for around three minutes. This new environmentally friendly development process is known as ECN-2. It is the standard development process for all modern motion picture color negative developing, includingFujifilmand other non-Kodak film manufacturers. All film stocks are specifically created for a particular development process, thus ECN-1 film could not be put into an ECN-2 development bath since the designs are incompatible.

The ECN-2 process has normally been reserved for high volume labs involving hundreds or thousands of feet of film in a linear processor. With companies like QWD that have made this available in a kit form for home use, this process now can be done on a small scale.

Eastman Color Positive

[edit]

Eastman Color Positive (ECP) is aphotographic processingsystem created byKodakin the 1950s for the development of monopackcolor positive print for direct projection motion picturefilm stock.It is part of the Eastmancolor family of products sold by Kodak.

ECP is not used for positive intermediate films because these are "pre-print" elements (e.g. archival or "protection" elements) and are never used for direct projection. One essential difference is the presence of an orange "mask" (i.e., effectively an orange base) on all films processed by Eastman Color Negative, and no "mask" (i.e., effectively a clear base) on all films processed by ECP.

The original process, known as ECP-1, was used from the 1950s to the mid-1970s, and involved development at approximately 25°C for around 7–9 minutes. Later research enabled faster development and moreenvironmentally friendlyfilm and process (and thus quickerphoto labturnaround time).

This process allowed a higher development temperature of 41.1°C for around three minutes. This new environmentally friendly development process is known as ECP-2. It is the standard development process for all modern motion picture color print developing, includingFujiand 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.

Originally, all Eastman Color films, ECN and ECP alike, were on triacetate base (no Eastman Color films were ever made on nitrate base), but recent practice has been for ECN elements to be on triacetate base, so these may be easily spliceable (usinglap-type cemented splices, also called "negative assembly" splices), and for ECP elements to be on polyester base, so these are not spliceable (except by usingbutt-type splices with polyester splicing tapes).

Examples of films that use Eastmancolor

[edit]

The 1959 British satirical comedy filmThe Mouse That Roaredwas filmed using the Eastmancolor process.

Eastmancolor became very popular in theSouth Indian film industryduring the early 1960s.
