E-6 process Guide, Meaning , Facts, Information and Description
The E-6 process (sometimes abbreviated to just E-6) is a process for developing color reversal (transparency) photographic film.Process E-6 is the most demanding photofinishing process in widespread use. It has more steps than the C-41 process used for color negatives. There is little processing latitude because there is no opportunity to correct density or color balance when printing.
It replaced the E-3 process in the late 1960s as this process used light for reversal, and produced transparencies that faded more quickly with repeated projection or the passage of time.
The K-12 and older Kodachrome processes are more involved than the E-6 process, and are performed only in specialized plants. Each of the three film layers is developed separately, and dyes are added during the process rather than being incorporated in the film base.
There are two families of E-6 processing chemistries. The original and standard is a six chemical step process. The 'rapid' or 'hobby' type chemistries use three chemical steps. Rinses, washes, stop baths and stabilizer (the optional final step of the process) are not counted in the counting of steps described below.
