Eastman Color Negative, specifically abbreviated as ECN, is a photographic processing system created by Kodak in the 1950s for the development of monopack color negative motion picture film stock.
The original process, known as ECN-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 environmentally friendlier film and process (and thus quicker photo lab turnaround time).
This process allowed a higher development temperature of 41.1° C for around 3 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, including Fuji and 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.

“A good deal of tyranny goes by the name of protection.”
—Crystal Eastman (1881–1928)
“The most refined skills of color printing, the intricate techniques of wide-angle photography, provide us pictures of trivia bigger and more real than life. We forget that we see trivia and notice only that the reproduction is so good. Man fulfils his dream and by photographic magic produces a precise image of the Grand Canyon. The result is not that he adores nature or beauty the more. Instead he adores his camera—and himself.”
—Daniel J. Boorstin (b. 1914)
“A negative judgment gives you more satisfaction than praise, provided it smacks of jealousy.”
—Jean Baudrillard (b. 1929)
