Maybe your math is off? 6X7 at 4000ppi is approx
120MPixel so color would be ~360 Mp not
700Mp. Unless your using 48bit color,
but then the 4X5 scan would be 600Mpixel
at 48bits
For the same amount of pixels, the larger
format at lower scan resolution is going
to look better due to less film grain
visablity.
there is know way of getting around
the fact that large format is better
than medium format in terms of image
quality.....

How do you think Johns LF (300MB+) scans would hold up against my Mamiya 7
(67)
shots scanned at 4000dpi (700MB+)? I think we are comparing scanners again.
