A lot, but almost certainly not all.
Can a flatbed scanner with high resolution (1200dpi)
scan these directly or
does it require using a lens setup?
For microfiche, 1200dpi is NOT high
resolution.
If we assume that each frame represents an 8.5x11 page, . . .
if the frame were an inch wide, that would be 1200 pixels for the width of
the page, or the eguivalent of about 150dpi
Half inch frames would be the equivalent of 75dpi.
Better than nothing, but far from ideal.
