Eastman Color Negative

Eastman Color Negative

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 more environmental friendly 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 environmental 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.
