Amen, Michael -

And that way the "filter" doesn't reduce the amount of light getting to the 
film :-)

I found a plug-in that will not only allow you to apply red, green and 
yellow filters but also to scan a color photograph and convert it to B&W 
with profiles from each of the B&W film types - TriX, TMax, Ilford, many more:

I'm sure you could work this out yourself by comparing the channels of the 
different films, but these are cheap enough and seem to work well.  I got 
the Delta 100, Tri-X, TMax, and Sepia filters.
