Film Spectral Sensitivity/Transmission Question.

[P3D Jeremy Hinton <Jeremy.Hinton@xxxxxxxxxxxxx>]

Previously posted to T3D.... but while the application 
is for stereo, the 'tech' bit is not specifically so. Perhaps
someone on P3D knows where to get this data?

Subject: Film Spectral Sensitivity/Transmission Question.

Is it possible to get hold of data on the spectral
sensitivity of each light sensitive component of
slide film?

Is the spectral sensitivity the same as the spectral
transmission when developed?

Is it possible to get hold of data on the spectral
transmission of each colour component of slide film?

I am particularly interested in Fuji Sensia 100, but
any input would help.

I am looking for this information because I have been 
using spectral data for electronic displays to select 
filters to 'optimise' anaglyphs. When the requirement 
is to maximise the transmission and eradicate obvious 
ghosting, this approach works well.  The results of
a simple download to film, however, are disappointing.
It is easy to seperate the colour components of a display 
(because you can give it a single R,G,or B input) and 
measure them independently.
Film is more tricky.

So far, I conclude that anaglyph images can be improved 
by using _different_ complementary filters at the image 
acquisition and display stages. (sounds simple now I've 
got there, so I wouldn't be surprised if a lot of you 
folks knew that).


Pease can anyone send me some data to play with!


Thank you


Jeremy
