Hi Natale,
To the best of my memory, in Sienna there was a scientific team working on
microamount techniques long ago. Maybe they will share some knowledge.
Otherwise, I am rather sceptic, because of the low accuracy of the X-ray
photographs.
Just try to do simple indexing of film taken data (ITO, TREOR, DICVOL) and
you will see the problem.
For scanning and digitising X-ray films you can see a thread in this list
archive (26-27. 04.1999). This works well for phase identification, but not
for structure determination.
If the grain size is your only problem (not the appliance price :)) ,
Huber's Guinier image foil seems to be your best solution.
If you learn something different from the stated here, I'll be very happy to
hear of it, since I'm still trying to solve the same problem at my end.
Success,
