I would try this - I really have a lot of difficulties with Vuescan, but it
DOES seem to work much of the time, and if I had the LS30 I'd use it by
default as Rob does.
That 10bits is apparently a real 10bits, and the black and white points do
work IME. There is sometimes a confusing problem though and that is it
seems to get confused around the edges of the frame and will use the
unexposed portion of the image in its black/white point measurement which
is not very useful. It seems that the cropping is not very accurate.
I think Ed would make it much more user friendly if the exposure algorithm
automatically applied a buffer which blanks out the outer 10% of the image
from exposure calculations.
