In color development, after reducing a silver atom in a silver halide crystal, the oxidized developing agent Chemical reaction, combines with a color coupler to form a color dye molecule. CD-3 is used in many processes including VNF-1
and the
E-6 process
The E-6 process (often abbreviated to E-6) is a chromogenic photographic process for developing Ektachrome, Fujichrome and other color reversal (also called slide or transparency) photographic film.
Unlike some color reversal processes (such ...
