Am I understanding you correctly to be saying that , target colours will be
more saturated than source colours if this "gamut expansion" is provided
and the target space is larger ( even only in some areas) than the source
space?
What I have gathered from your answers is that in theory, that is according
to the specifications, there are no specific provisions made for increasing
saturation, but only to "preserve" ( ie. maintain ) saturation levels as
they existed in the source space. However it seems that there is a
consensus that, in practise saturation rendering does increase saturation.
The explanation given is that, the vendor, is deciding to shape his product
to increase chances of pleasing his customer. like adding sugar to tomato
sauce.
What puzzles me is why graphic artists would rely on rendering intents to
correct their imagery , certainly editing software is a far more precise
tool to insure colours have been saturated to the edge of gamut, and at the
same time insuring that colours that have been left deliberately less
saturated would remain so, even for bar graphs I would think that this would
be important.
Thanks for your help understanding
Eugene Appert.
