I can't answer that question, but on a related matter, I have
a small article on Michael Reichmann's 'Luminous Landscape' website.
It describes my experiments to track down the source of the fine
black speckles ('pepper grain') seen in some high resolution scans,
particularly with scanners like the Minoltas. There are some
explanatory photographs, including the film-base bubbles that I
believe are responsible for the pepper grain effect.
My piece is at the end of Nick Rains' informative article on
'pepper grain'.
