Re: filmscanners: which space?

Which is fine by me - so long as RxGxBx look the same as Rx'Gx'Bx' my result
will be what I want it to be.

| That's not exactly the case.  What is the case is that a particular Hue,
| Intensity value - what our eyes perceive as a unique 'color value' can be
| rendered with multiple combinations of RGB.  The same is not true for CYMK
| So when you map from RGB into ANY color space, you essentially lose some
| information.  Namely you lose the mapping back to the original value
| settings.  That doesn't mean you can't get back to an RGB triplet that
| look the same, but it does mean that say if you had set the RGB triplet
| value to Rx,Gy,Bz then mapped to CYMK and you went back, Rx',Gy',Bz' might
| not have
| x=x',y=y',z=z'.
