    VNF requires BZA and ED in it. E6 does not need BZA but does need ED in it.

    Without BZA and ED in VNF, Color dmax will be low and color shifted.

    E6 films have higher sharpness, better color rendition and finer grain. This makes it necessary to develop the emulsions longer in the first developer.

    So without the ED and BZA how low a dmax should I get?
    My first attempt resulted is completely clear film.
    That's when I developed at E6 times.
    On my second attempt I reduced the development times to the VNF-1 numbers.
    This time all the exposed areas are clear and non exposed areas are a very light purple.
    If I had all the exact chemistry I would say the film is bad or too old.
    But until I can get some ED and BZA I will have to blame my chemistry.

    I would expect a color developer without ED or BZA would have a dmax in the range of 1/2 or 2/3 that of a real process. I would expect to see a speed increase due to the lower dmax.
