E-6 process

E-6 is a standard color development process in the development of chemical photography reversal film for color slides. The "E" stands for Ektachrome; the name comes from the inventor of this method, Kodak. Other companies such as Agfa, Fujifilm Tetenal or provide functionally equivalent dia- development processes under other names, so he was referred to, for example, of Agfa AP 44.


The Ektachrome E-6 Process sparked in 1976 at the Kodak polluting predecessor E-4 off shortly after it was adopted by other manufacturers as a standard process. All current reversal films are now developed in the E-6 process; the only exception to 2009 Kodachrome film. He was processed in much more complex systems K-14 process, which was conducted in late 2010 for the last time.


For the E-6 process seven bathrooms are needed in the original form; it takes 32 minutes; a shorter and more recent variant comes out with three bathrooms and lasts 26 minutes. The processing temperature is in both cases at 38 degrees Celsius.
