While you will definitely get some sort of image on film, like Sandy I find
it hard to believe that you would get anything remotely realistic in terms
of color rendering using ortho film for all three separation.

Are you using a McBeth ColorChecker for your test?

I don't even know if it is still available, or how much it costs, but
Kodak's Panalure RC might be an alternative. I just read under Usenet that
Kodak just got on the WWW, with its catalogs and services. I'll see if I
can find it and check.

Has anyone out there used Panalure paper for color separations?
