So from what I have found here ECN developer is CD3 and E6 developer is CD3 but E6 developer can't be used in place of ECN developer because it will fog the film (Go find an ECN thread where PE has commented). With all that being said, could ECN film be processed in the entire E6 process to provide transparencies? What is it that would make it chemically work/not work and what practical limitations would there be on the implementation of this.
** This is a purely hypothetical post and I am not planning on finding ECN films just to try this out. **
