Andrew - When I wrote "you have used dE as both a sword and a shield,"
I figured that readers would understand the inference was that dE is a
method for determining a colorimetric match - that dE is pretty much
colorimetry itself.
As an expert in profiling and color management you've insisted that
colorimetric matches aren't the purpose of profiling or a color
managed workflow. Yet you, and others, offer dE as a measure of the
quality of a profile or workflow. Thus, colorimetric matches play an
important part in evaluating your work - no? It's a good thing when
it promotes the case for profiling and its shortcomings are also a
good thing as that promotes the need for skilled professionals at the
helm - sword and shield.
You understand the confusion this must cause - I believe that's what
you mean by the "rabbit hole". But I don't believe I've heard you
give a satisfactory answer in this thread as to why colorimetric
matching is and isn't important - all at the same time. You've only
offered that it's not important to a majority of photographers. It
must be too difficult for people to understand so we have to settle
for it as the rabbit hole instead. That saves time and possibly even
more confusion. It protects the colorimetric grail searchers from
themselves?
You've asked, in a challenging way, for a definition of "colorimetric"
from participants in this thread so I figure you're quite ready to
spring on any definition with answers that would belittle the pursuit
of colorimetric matching. Do you have a definition that's better than
the deficient ones in use? I think that might clear up some of the
confusion.
May I say that this topic might be interesting to more people than you
think, and with your professional experience I bet you can lay it all
out in a clear way so that this rabbit hole isn't so dark and
mysterious. This topic has appeared in the colorsync-users list a
number of times and this time it seems that the subject of RPP along
with some ideas from members has brought it back with a little more
enthusiasm.
