I'm with you on that. When you see so much time spent spent in the wonders
of ICC and what you can do with it. Every once and a while it bothers me
that, as you, and many others on this list (even the Winnepegonians!) that
I take the time to look at the numbers in the ACTUAL applications that we
use everyday; especially Photoshop but also in apps that are specialised in
acquisition such as Linocolor/Newcolor. The revelation if you like is that
the perceptual mapping has improved to the point where by the numbers (for
those who I rely on so much) do you really see a big difference between
perceptual and colorimetric ? A few years ago after reading Marguilus one
would believe that ALL this stuff is whacked but in fact silently the colour
scientists have applied phenomenal improvements in the perceptual mapping.
It's very important to us and often the marcom's can't evolve the
descriptions of the work done by these colour scientist.
Look closely at the differences between recent profilers perceptual mapping
and colorimetric and you'll find numerically little difference but justly so
in the tonal graduations. It seems Henrik and others had subtly mentioned
this, but us, the hard headed users have to judge by the proof and/or the
numbers. Let's take a step back, look at the numbers, and congratulate the
programmers who have given us the tools which let us make our images
portable within the limits of the chosen (1993? M.Stokes) limits that we
use. In this day it's when you throw a ball of wax at say Dan Caldwell that
will return the prettiest ball of wax you've ever seen that you realise how
far we've come perceptually....
