yes, I would also say that gamuts vary in shape as well as volume. It may be an oversimplification to call one larger or smaller than the other…
hard to say…
Pro includes (will include) the ability to calculate gamut volume… I suspect this will generate some controversy… This is one of the many features that we need to ensure is as accurate as possible before we ship…
You are right, your appreciation is more correct that saying “one is larger that the other”, but in this case I think Endura gamut is actually larger because it almost totally contains the Crystal Archive gamut, and because both are RA4 photographic papers, thet shape of both gamuts is very similar.
Regarding ColorThink Pro gamut measurement feature, why do you think it will generate controversy? If you count the cubic delta e units you have the total volume and if one volume is larger than the other, then, the gamut is larger, am I correct?
I think that, what can be controversial is the real world usability of the gamut, because that can depend a lot in the shape and not that much in the total volume. In other words, you can have a very large gamut with a shape that’s useless for reproducing real world images.
exactly. I have some concern that the gamut volume number will be used by people to say one device “is better” than another when it really depends on where in the gamut it is larger. It is a useful tool but a blunt instrument that should be wielded carefully
