        Some of the posts to this thread seem to be confused as to what is
"softening" the image.  It is NOT Vuescan's "dust removal" algorithm
... it IS the "grain reduction" algorithm which Ed has added to
"scrub" and "scour".  My impression is any qualifier (weak - strong)
for "dust removal" no longer exists  (... altho I don't know how Ed
applies this to non-IR scanners ...), ... but there are 2 degrees of
grain reduction.
        Selecting "dust removal" without "grain reduction" is done by
selecting "clean", altho there is no method of selecting "grain
reduction" w/o "dust removal".
