It may, but I think Julian's point is valid which is that for
a given sensitivity from the analog circuitry, changing the
A/D won't make any difference to the density ranges
that the analog circuitry resolves.  It only increases the
accuracy with which we read the range of analog values
that the CCD *does* resolve.
