P3D Color negative compensation

>Color negatives have a strong (orange?) color bias - this is normally
removed with filters in the printing process. If you scan and just reverse
the colors, you'll still have a color bias in the "other" direction.
If you mathematically compensate, I expect you'll lose some density range
in some of the colors in the final result (at least for a scanner that was
intended for positives). (Do professional Photo-CD scanners use filters, or

just mathematical compensation for color bias?)<

I use the Nikon Colorscan for scanning slides and negatives. Its software
has an automatic color negative setting that compensates, mathematically
I'm sure, for the color difference. The result is never perfect color, but
it's well within striking distance for Photoshop to tweak. I've always been
quite happy with the result. In fact, I now prefer this method to scanning
a print.
