Ektachrome is a brand name owned by Kodak for a range of transparency still and motion picture films available in most formats, including 35 mm and sheet sizes to 11x14 inch size. A brand is a collection of Images and ideas representing an economic producer more specifically it refers to the descriptive verbal attributes and concrete symbols such as a Eastman Kodak Company ( is an American multinational Public company which produces imaging and photographic materials and equipment In Photography, a reversal film is a still positive image created on a transparent base using photochemical means This article is mainly concerned with Still photography film For Motion picture film please see Film stock. 35 mm film is the basic Film gauge most commonly used for both still Photography and Motion pictures, and remains relatively unchanged since its Readers familiar with old National Geographic magazines will recall the distinctive look of Ektachrome, used for decades for color shots wherever Kodachrome was too slow. Overview The NGS's historical mission is "to increase and diffuse geographic knowledge while promoting the conservation of the world's cultural historical and natural Kodachrome is the trademarked name of a brand of color reversal film sold by Eastman Kodak. [1]

Ektachrome, initially developed in the early 1940s, allowed professionals and amateurs alike to process their own films. The 1940s decade ran from 1940 to 1949 Events and trends The 1940s was a period between the radical 1930s and the conservative 1950s which also leads the period to be It also made color reversal film more practical in larger formats, and the Kodachrome Professional film in sheet sizes was later discontinued. Kodachrome is the trademarked name of a brand of color reversal film sold by Eastman Kodak.

Ektachrome, unlike Kodachrome, was a product that small professional labs could afford equipment to develop. Kodachrome is the trademarked name of a brand of color reversal film sold by Eastman Kodak. Many process variants (designated E-1 through E-6) were used to develop it over the years. Modern Ektachrome films are developed using the E-6 process, which can be carried out by small labs or by an amateur using a basic film tank and tempering bath to maintain the temperature at 100°F (38°C). The E-6 process (often abbreviated to just E-6) is a Photographic processing system for developing Ektachrome, Fujichrome, and other color

Although the Ektachrome name was once associated with both amateur and professional films, Kodak, as of 2006, uses the Ektachrome brand for professional films. Year 2006 ( MMVI) was a Common year starting on Sunday of the Gregorian calendar. Consumer Kodak E-6 films are now branded Elite Chrome.

Ektachrome film was used when shooting part of the 1999 film Three Kings and cross processed to give a unique appearance. Three Kings is a 1999 action - comedy - drama War film written and directed by David O Cross processing (sometimes abbreviated to xpro) is the procedure of deliberately processing Photographic film in a chemical solution intended for a different

Although Kodachrome is often considered a superior film due to its archival qualities and color palette, advances in dye and coupler technology have blurred the boundaries between the differing processes, along with Kodak having abandoned Kodachrome research & development since the mid 1990's. The E-6 process (often abbreviated to just E-6) is a Photographic processing system for developing Ektachrome, Fujichrome, and other color Kodachrome is the trademarked name of a brand of color reversal film sold by Eastman Kodak. Furthermore, the developing of Kodachrome has always required a complex, fickle process requiring an on-site analytical lab and today (2007) requiring a turnaround of several days to allow for shipping times to the one remaining Kodachrome processing facility. Year 2007 ( MMVII) was a Common year starting on Monday of the Gregorian calendar in the 21st century.

By contrast, small professional labs have been able to process Ektachrome on-site since the 1950s, with product safety and effluent discharge having been drastically improved since the 1970s, when Kodak reformulated their entire color chemistry lineup. The 1950s Decade refers to the years of 1950 to 1959 inclusive Amateur labs are also able to process Ektachrome within an hour using a rotary tube processor (made by Jobo, WingLynch or PhotoTherm), sink-line, or even by hand inversion in a small drum.

Ektachrome variants

There were some other Ektachrome process for 16 mm motion picture films:

The following processes were used for amateur Ektachrome super 8 mm movie film:

Process history

E-1
Initial Ektachrome process for sheet film (1942-c. 1950s)
E-2
Initial Ektachrome process for roll film and 135 film (1942-1966)
E-3
Updated 'professional' Ektachrome process for sheet film and Kodak EP professional rollfilm (c. See also Ektachrome for full details of Kodak E-series processes 1950's to 1976)
E-4
Updated Ektachrome process for roll film and 135 film (1966-1996, see note)
E-5
Research project, only saw minor use in a revised form as the aerial film process AR-5
E-6
Current Ektachrome process used for all major color reversal films and formats, first released in 1977. See also Ektachrome for full details of Kodak E-series processes The E-6 process (often abbreviated to just E-6) is a Photographic processing system for developing Ektachrome, Fujichrome, and other color The conditioner, bleach and stabilizer baths were modified in the mid-1990s to remove the formaldehyde from the stabilizer: This change was indicated by changing the names of the conditioner step to pre-bleach step, and the stabilizer step to the final rinse step
E-6P
Used specifically for Kodak Ektachrome EPH ISO 1600 film, which has a true speed of ISO 400 but is exposed at EI 1600 and push processed two stops in the first developer bath (10:00 @100. Film speed is the measure of a photographic film's sensitivity to Light. Push processing is a term from Photography, referring to a development technique that increases the speed of the film being processed 0F) to achieve the ISO 1600 speed rating.

Other film manufacturers use their own designations for nearly identical processes. They include Fujifilm's process CR-55 (E-4) and CR-56 (cross-licensed with Kodak's process E-6; but with slight variations in the first developer); and the now-discontinued Agfachrome and Konica's CRK-2 (E-6 equivalent). is a Japanese company known for its Photographic film and Cameras Fujifilm is the world’s largest photographic and imaging company. For the Albanian thinker Faik Konica (also known as Faik Bey Konitza) see Faik Konica was a Japanese manufacturer of among other products

High Speed Ektachrome, announced in 1959[1] provided an ASA 160 color film, which was much faster than Kodachrome. In 1968, Kodak started offering push processing of this film, allowing it to be used at ASA 400. [2]

The E-4 process was generally stopped after 1977, although continued in use for Kodak PCF (Photomicrography Color Film) until the 1980s, and for Kodak IE (Color Infra-red film) until 1996. Photography (fә'tɒgrәfi or fә'tɑːgrәfi (from Greek φωτο and γραφία is the process and Art of recording pictures by means of capturing This was due to a legal commitment by Kodak to provide the process for 30 years. Eastman Kodak Company ( is an American multinational Public company which produces imaging and photographic materials and equipment

The Ektachrome process differs significantly to the Agfa Process AP-41, used generally until 1983 to develop films such as Agfachrome CT18 and 50s Professional.
