If you wanted to scan 52x fiche at an effective resolution of 200dpi
("fine" fax quality, which isn't actually "fine" IMHO), you need 10400
dpi. 6400 dpi gets you effective 123 dpi, which might not be
completely useless, but certainly wouldn't be very good.
Ah.. Good some numbers to work to.
It helps identify two methods:
Scan fiche as is:
Magnify and photograph.
In fact modern cameras are like a hi res TV system.
