You need some kind of 3D visualizer to do this in any rational way, which
allows you to display your image data in 3D, and shows you, in 3D again, the
result of conversion. If you convert from ProPhoto to AdobeRGB there is for
the moment only one type conversion implemented and that is RelCol by virtue
of the matrices/TRC embedded in both of these profiles and the fact that in
this instance conversion takes place in XYZ and not Lab.
Chromix ColorThink allows such a visualization. So is X-Rite ColorShop X.
And so is Monaco GamutWorks. And there is also the Windows freeware Beta 3
profiler (www.littlecms.com). GamutWorks will go as far as allow calculating
DeltaEs between your colors in ProPhoto and AdobeRGB. I'm not familiar
enough, yet, with the other two package to say whether they have a similar
capability. But you're welcome to ask.
