photos of autorads

[John Korte]

Greetings,
I have been trying to take photos of autorads to scan into a computer, the
problem is that my photos are consistently blue-green.  The autorads are
backlit from a typical light box, photos are taken directly overhead with a
35mm SLR, with a 90mm macro lens.  I've been using 200 ASA Kodak "Gold"
film (but I've also tried various color slide film also)  Any idea of what
filters I could use to curb this?
Thanks,
John Korte
