Having left the 8/16 hobbyhorse, but Im interested in
the whole RAW data thing.

My workflow for a neg roll is thus: (using Vuescan):
   scan neg profile (the vuescan film profile)
loop
   scan frame
   save RAW data
   save scanner corrected TIF (16 bit)
   correct in Photoshop as required
   save PNg/JPG/small files for general viewing

I archive the RAW files as Ive learnt (early
in my scanning days) that Vuescans colour models
improve over time, and I can get significant
differences ... well, to me at least, with a
review of particularly difficult frames.

Can I assume that the RAW scan is just that,
it will always be the same w.r.t a particular
scanner and this negative, forgiving minor
variations, but will vary on the scanning software.
