Ummm, if you are shooting slide materials under flourescent-only
illumination, an FL-D will leave a considerable amount of green
(it works well with mixed daylight and flourescent, though).
More universally useable for decent correction is a cc30M
filter, available in glass from Tiffen (I remount the glass
in better rims, and make sure to clean the glass before use
since Tiffen glass seems to "spontaneously" fog...), or in
gel form from Kodak (the gel can be cut to a circle that will
just fit behind a UV filter).
