Yup, I took a couple and looked at them under a microscope at low power and
what you describe is definitely what is happening - one side has a slightly
smaller aperture. However, this still says the Scanwit is able to "see
though" that one smaller side's edge. And what the result seems to be is
that area has higher contrast with no more noise than the film area next to
I think the bottom line is that my next scanner will definitely have a
manual exposure mode!
