Ektachrome Film
American · Ektachrome 1946–present
The colour transparency film you could develop yourself. Ektachrome traded Kodachrome's extraordinary dyes for a process a working photographer could run in a hotel bathroom, and for decades that mattered more.
Origin
Introduced by Kodak in 1946 as a professional alternative, Ektachrome used the standard chromogenic approach that every other colour film would eventually adopt. Its practical advantage was decisive for photojournalism and commercial work: E-6 processing takes around half an hour and can be done anywhere, so a photographer on assignment could develop, check and reshoot the same day. It was discontinued in 2012 and, unusually, brought back in 2018 after sustained demand.
Technique
Colour couplers are built into the three emulsion layers themselves, so processing is a single standard sequence — first developer, reversal, colour developer, bleach, fix — identical for every roll. Reversal processing produces a positive transparency directly on the film, with no negative and no print stage, which is why transparency film was the professional standard for reproduction: what the printer received was the photograph itself, not an interpretation of it. Exposure latitude is very narrow, around half a stop, and the discipline of exposing precisely for transparency shaped a generation of practice.
The palette
Cooler and more neutral than Kodachrome, with cleaner blues and greens and a less pronounced warm bias — the two films were chosen against each other for that reason, and photographers had strong preferences. Later versions were tuned for specific tasks: the E100 range for accuracy and skin, the higher-saturation stocks for landscape. Its blues in particular have a clarity that made it the standard for skies, water and anything requiring cool accuracy.
Legacy
Ektachrome and its equivalents defined the look of the picture magazine and the corporate annual report from the 1950s through the 1990s. Its archival weakness is real: early Ektachrome has faded and shifted noticeably, often toward magenta, where Kodachrome of the same age has not, and a good deal of twentieth-century colour photojournalism is in poorer condition than its black-and-white contemporaries.
