Robbie,
Here are the specifications for VFN-1, as published by Kodak:
http://motion.kodak.com/motion/uploadedFiles/US_plugins_acrobat_en_motion_support_processing_h2411_h2411.pdf
If you refer to pages 23-25, you'll find the formulas for the first
developer and color developer, which are the critical components (on the
processing side) that will determine the overall hue and saturation of the
image. Also, please note that the module gives two alternative formulas
appended with the abbreviation LC which stands for Low Contrast (so,
probably want to avoid those formulas).
The first developer is a very straightforward PQ developer with added
thiocyanate; you shouldn't have any difficulties finding these ingredients,
with the exception of the sequestering agent (Quadrafos). However, by using
distilled water to mix the developer, you can avoid the use of this
ingredient...
The color developer, on the other hand, is a bit more complex to mix from
scratch. However, since it's purpose is just to act as a redeveloper of the
residual halides, it can be replaced with any other developer that retains
the same color developing agent (i.e CD3). This includes ECN developer (not
C-41) as well as the color developer in E6. The formula for ECN developer
can be found here:

Bleach and fix are the same for all color processes -- Just use what's most
readily available to you, or mix a simple ferricyanide bleach (15.0g
Potassium Bromide / 15.0g Potassium Ferricyanide / Dilute to 1 Liter) and
then use that in conjunction with any fix -- B/W or otherwise...
As for altering the process to get higher contrast or color, you can try
experimenting with the first developer. For instance, you could increase
the ratio of hydroquinone to phenidone, or increase the alkalinity of the
developer...you could also use there LC formulas to interpolate a
possible equation for increasing the contrast
Anyway, hope this helps,

Does anyone have a formula for processing the older color reversal 7240
film , which was intended for VNF-1 process, but possible in E6. I'm aware
E6 process will provide result, but I'm hoping to achieve a higher contrast
more saturated image than what E6 results with this stock. Therefore, does
anyone perhaps have alterations to E6 or a VNF-like formula that may
produce higher contrast and color? Or perhaps a source? I'm hoping to
process as reversal rather than crossprocess. Thanks for any assistance .
