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)
“He could jazz up the map-reading class by having a full-size color photograph of Betty Grable in a bathing suit, with a co- ordinate grid system laid over it. The instructor could point to different parts of her and say, “Give me the co-ordinates.”... The Major could see every unit in the Army using his idea.... Hot dog!”
—Norman Mailer (b. 1923)
“Most literature on the culture of adolescence focuses on peer pressure as a negative force. Warnings about the “wrong crowd” read like tornado alerts in parent manuals. . . . It is a relative term that means different things in different places. In Fort Wayne, for example, the wrong crowd meant hanging out with liberal Democrats. In Connecticut, it meant kids who weren’t planning to get a Ph.D. from Yale.”
—Mary Kay Blakely (20th century)
