Yeah, 16bpp -vs- 8bpp would add enough resolution to make all this stuff
pretty academic and low-contrast films win out. I'm basing the original idea
on having done scans of low-contrast prints, and wishing there was more
range in the image, because when I do expand it to get the contrast I want,
it just ends up looking pretty iffy because the lack of different levels in
the original means that mid-tone gradients end up being all stripy-looking.
