Not trying to be a smart ass but given the above statement, why not just
have an internegative produced (if you want a negative) from the tranny and
produce the prints the traditional wet photographic way rather than fighting
with the limitations of the scanner which may also turn out to be
limitations of inkjet printers?

Otherwise, you might try (if they are mounted trannies) sandwiching the
approrpriate color correction filters with the negative that will bring the
problematic colors within digitally correctable limits and scan the
sandwich.  I think you will find that some colors that are reproducable on
positive film are not reproducable on negative film or in print digitally or
traditionally.

I have a difficult scan problem : (

The negs are taken through a microscope and are of rocks. Some or every
second one has been
lit by fluorescence light source and the base colour comes out a golden
yellow and the other
colours are sort of fluro greens, greens to blacks.

When the scans are done either in Nikon Scan or Vuescan they come out
towards magenta
tones. Having tried to reverse this with the controls in either programme
there is
insufficient range and look yuck. I use auto exposure auto balance then try
to re-balance
with the control panel before the scan.

I have been correcting them in PS but don't seem to replicate a tranny image
of the subject
matter. ( if tranny film is used in place of neg film).  Its like chasing my
tail around
either way.

I have suggested that tranny film is used in place of neg material but
photographic prints
are some times required.

Can anyone suggest another technique that will give me a closer colour scan
than what I'm
getting now.

Thanks
Rob
