I wanted to play with setting the exposure and mask values as
described in the help file. My procedure was to try and pick a
normally exposed negative with "auto" settings for exposure and mask
... but as it turned out the image should have been good for exposure,
but it didn't contain neutral blacks. So I fixed the exposure
settings and left the mask setting to auto. I then put in a blank
frame which should have represented a "black" frame. However, when I
scanned it didn't turn out black, rather a grainy neutral shade of
"off white". Why, given the previously determined exposure, did this
scan not result in black?
(Hmmmm? ... let me ask the question, but play with different
whitepoint and blackpoint settings)
