Marvin, could you possibly paraphrase the question?  I'm not sure I understand
what you're asking.

Actually with the LS30 and silver based B&W film the problem seems to be
dynamic range, not so much grain.  One particular roll of FP4 I tried produced
horribly posterised results in Nikonscan; it simply couldn't get enough
data in 8 bits of monochrome.  Vuescan is better since it accesses all 10
bits per channel the hardware produces, but I think more bits and a brighter
light source are probably needed.  Tony Sleep has mentioned about aliasing
in silver films in the past.  Given the poor results I got initially, I
haven't persisted with trying to scan such films, but stuck to T400CN instead,
or printed them with an enlarger.
