Hi,

 

For reasonable testing a proper spectrometer would be needed, which is way beyond Klaus' setup.  Please see http://www.kenkotokinausa.com/pictures/F...ission.gif for a transmission spectrum for a few Hoya warm-up filters.  How to connect from such a graph to a meaningful discussion of photographic relevance is beyond me.  In general, I believe that the transmission spectrum has a significant effect on the image, which is not easy to correct in PS.  Would take a real colour profile to do so.
