It really is hard to compare apples (film grain) and apples
(digital pixels).

When I switched from a 2700dpi scanner (Polaroid 35plus) to
a 4000dpi scanner (Polaroid 4000),  I noticed something
similar.  Closer inspection revealed that the 4000dpi model
was better at scanning details in the film grain than the
older model.

Photographs taken with the D30 don't have grain,  but
pixels.  Digital pixels are uniform and very clearly
separated.

For film,  the smallest unit of information is the film
grain,  which may overlap,  and which have a more irregular
shape.

I think that in order to properly scan film,  one needs to
be able to scan the details in the film grain,  so this
requires a lot of resolution.  But only a fraction of that
will contain "real" information about the photographed
object.

This is due to the limitations of the film,  and it becomes
apparent when comparing 35mm with medium or large format
prints of the same object.  The "tonality" will appear better
with increased film size (while keeping the print size
the same).

This of course raises the question of how to archive
photographs,  and another one about the archival qualities
of film.  Velvia for example is not archival - colors fade
relatively quickly.  Whatever happened to good old Kodachome
64 ...

Again,  digital has its own set of problems here,  most
prominent I would say are compatibility problems of storage
media.
