I assumed that ICE was some sort of dumb gimmick and
that image quality would suffer from using it.
I'm happy to say that I was quite wrong about this.
In fact, when I consider the countless hours I've spent
in the last few years spotting and retouching scans, I
kinda kick myself...
However... there IS a price to pay, and it gets back
to the LEDs vs. cold-cathode lighting issue, I think.
If I'm not mistaken, ICE requires IR-LED illumination.
The Nikons have this, the Polaroids don't. But it
also seems that shallow depth-of-focus may be a side-
effect of LED illumination, at least according to one
of theories floating around. To wit: the LEDs are
less bright than cold-cathode, hence wider apertures
(and lower depth-of-focus) in the internal optics.
It would be interesting to put this to the test, somehow,
perhaps with deliberately bent or curved media.
Shallow depth of focus *is* an issue on the 8000,
when scanning 645. I have to be extremely careful
loading the filmstrips in their holders to ensure
that they're quite flat. It's often a hit-and-miss
thing. Not so much an issue on 35 mm filmstrips.
