Ektachrome


Ektachrome is a brand name owned by Kodak for a range of transparency, still, and motion picture films previously available in many formats, including 35 mm and sheet sizes to 11×14 inch size. Ektachrome has a distinctive look that became familiar to many readers of National Geographic, which used it extensively for color photographs for decades in settings where Kodachrome was too slow. Ektachrome is able to take photos at shutter speeds of 1/10,000 of a second without filters.

Ektachrome, initially developed in the early 1940s, allowed professionals and amateurs alike to process their own films. It also made color reversal film more practical in larger formats, and the Kodachrome Professional film in sheet sizes was later discontinued.

Whereas the development process used by Kodachrome is technically intricate and beyond the means of amateur photographers and smaller photographic labs, Ektachrome processing is simpler, and small professional labs could afford equipment to develop the film. 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 a keen amateur using a basic film tank and tempering bath to maintain the temperature at 100 °F (38 °C).

Ektachrome has been used occasionally as a motion picture film stock, such as in the 1999 film Three Kings and the 2006 film Inside Man, in which each used cross processing in C-41 color negative chemistry to give a unique appearance.

Several years before Ektachrome's discontinuation, some of Kodak's consumer E-6 films were rebranded as Elite Chrome. In late 2009, Kodak announced the discontinuation of Ektachrome 64T (EPY) and Ektachrome 100 Plus (EPP) films, citing declining sales. On February 4, 2011, Kodak announced the discontinuance of Ektachrome 200 on its website. On March 1, 2012 Kodak announced the discontinuance of three color Ektachrome films. In December 2012 Kodak announced its discontinuance of Ektachrome 100D color reversal movie film in certain formats. By late 2013, all Ektachrome products were discontinued.
