It's wrong to plot out the RGB space they encode their images in as if it was an output device gamut. Consider : if you set exposure correctly, then every possible light spectrum will generate camera RGB's that are within the range 0..1. Input devices have a different limitation in regard to color :- metameric mismatch. They can (and often do) "see" color differently to humans, if their sensor spectral sensitivities are not the same as the human eye. But qualifying this limitation is not done by plotting out the device value limits of a best fit translation of their whole RGB space to XYZ. Graeme Gill.
