Philip:
      How do you reproduce these special "spectral response" colors in Photoshop
and when combined do they equal white?  If you are not reproducing the color of
these filters in Photoshop, then you are just fooling yourself.  The space
telescope uses special spectral filters, but according to David Malin is not
producing true color.
     The real advantage of tricolor is the quality of the detector ... i.e. Tech
Pan or CCD's.
