Hi 
Why not move to the future and do away with film and go digital using
the video camera on the scope and a cheap frame grabber (something like
WIN TV card) and then you don't have to train the phot lab to do it
properly as WYSIWYG. And if you still wnat transparencies load it into
POwerpoint or Harvard Graphics and send them to soembody to make sldes
from a powerpoint presentation. 
This works very well with both light and fluorescence photomicroscopy -
we use a standard JVC single chip camera for light and a DP10 digital
Olympus for recording the  ImmunoFluorsence on renals and skin work.
This has produced somevery good photgraphs and being able save as a
named item saves all the palaver when the prints / slides come back and
what was this immuno of and at what mag etc. (Can eat up your hard disc
space but a CDR can save alot of trouble).
Also if it isn't white enough you can adjust using image nehancement to
get the picture dead right, you can also use it for quantification if
you want to.
