Okay, the hunt is still on but the 8000 is CAD$1200 cheaper than the
9000. (I guess Nikon Canada have a few in inventory to get rid of...)
So what should I expect to be different in actual performance?
The 9000 uses 16-bits per channel while the 8000 uses 14-bits.
This means the 9000 will scan deep blacks better, with more overhead.
The 9000 has Pro-ICE, while the 8000 has ICE-4.
This means that the 9000 can clean up any dirt on Kodachrome a bit
better than other ICE equipped scanners but, like all ICE equipped
scanners, it still has difficulty because of the emulsion structure.
Any skeltons in the closet with the 8000?
The main issue is a type of banding, apparently caused by a mechanical
resonance. The solution is to enable the "fine scan" mode, which
deselects 2 of the 3 CCD lines. This eliminates any banding, giving
perfect results, but at the expense of each scan taking 3 times longer
than the advertised time. If you scan with ICE, autoexposure and
autofocus enabled, this doesn't make much difference to the overall scan
time, since it doesn't affect the time for these options.
LED's what?
Like all Nikons, it uses LEDs for illumination. The 9000 & 8000
scanners are equipped with a tri-linear CCD, but this is not colour
filtered. Instead of the conventional approach, the tri-linear CCD is
used to reduce the scan time by scanning three lines at once. As
mentioned above, the problem that beset the 8000 was that the larger
steps required by the scanner head to achieve this high speed scan set
up a mechanical resonance with many units, causing a discontinuity in
the scan position which appeared as a form of banding in the image. The
solution to the problem on the 8000 is to operate in the slower scan
mode using only one of the CCD lines.
