It is conceivable that the film processing may be at
fault. It sounds like the film may not have been
properly bleached and/or fixed. There are a couple of
ways to check for this. The easiest would be to take
the film to a photo lab and have it rebleached and
fixed. This will not harm properly processed film. You
can then repeat the scan and see if your results
improve. Another way is to examine the film in total
visual darkness with an infrared viewer. A lot of
cheap webcams and surveillance cameras can do this.
The film should appear totally transparent. If you see
any image, the film has residual silver, which proper
bleaching and fixing remove.

I have scanner HCT 4x5 transparency targets for both
Fujichrome and
Ektachrome material as well as an Ektachrome IT8. I
use the profiles
created from them with the corresponding transparency
material (Kodak
for Kodak...Fuji for Fuji). There are times when
everything is
hunky-dory...the scans come out great. However, there
are times when
the
profiles just don't seem to represent the material I'm
scanning very
well. Often scans will come out with a bluish or
reddish cast. This has
happened with both Fuji and Kodak media (I'm referring
to 4x5 film, not
35mm, and not kodachrome). I have tested my scanner
for repeatabilty
and
its rock solid (Hell 3800) and have had color
consultants check out my
profiles....a-ok. <<<
