Just upgraded to New G4 and thanks to Vuescan finally got my LS 2000
and Old Apple color one on scsi to operate.
Only problem is that Vuescan reads the 1200/30 color one as a CS
600/30, so the max I can scan at is 600dpi. I believe that the 1200/30
is 1200dpi optical (up to 4800 interpolated). As interpolation was
probably a function of apple software i can understand this, however i
thought i would be able to get 1200optical through Vuescan. Any one
know if this is correct?

Thanks in advance

There are also other scanners that can step in finer increments (in the slow
scan direction) than the sensel pitch (the fast scan direction). This allows
for supersampling in one direction, which does improve the MTF response in
that direction. I've experienced this improvement with my Epson 2450, and it
can be demonstrated with the Minolta MultiPro.

Although it would complicate the postprocessing, it would be useful if
VueScan would exploit this possibility to further enhance its superior data
extraction.
One could think of either interpolating the missing pixels in the fastscan
direction, or size reducing in the slowscan direction (the latter giving
higher quality, the former not losing any). This would create better detail
contrast and less chance of grain aliasing.
Maybe other scanners can be improved as well?
