Terry - You've been in the profiling arena for a long time so I
believe that you already know what you're going to encounter if you're
about to get into art reproduction. I apologize for not making the
distinction in earlier posts but I'm still a little reluctant to
dogmatically say that a colorimetric "match" in the field isn't a
worthwhile challenge too. But, my interest in this thread is mainly
over art repro and I'll try to make that clear in future posts. I
think that the variables in field will be a side challenge, important
considerations - but not something that should cause one to dismiss a
colorimetric approach in the field.
Nature throws curve balls and so do paints and other materials used in
artwork. But it seems that at least some of the limitations for
colorimetric work could have been addressed and worked out a long time
ago as profiling and the ICC initiative began. I believe the focus on
color management for big software companies and printing companies
took the ball and defined the game - but that's just me doing
speculation. Anyhow, colorimetric matching just didn't get done. I
guess Rodney's point about there being very little interest in the
approach had a lot of weight in the beginning and it's still a factor.
I've made ICC profiles under studio conditions for every shot I've
made of art and printer profiles aplenty but I've been overall
disappointed. Not disappointed in the concept but disappointed in the
colorimetric failures and how close it seemed that it could be
accomplished if only there was something else. Some results still
tell me loud and clear that I'm better off without profiling - just
taking what the camera gives me.
When ACR first appeared I was excited that this might be helpful for
art repro. I combined ICC profiles and ACR and was sometimes pleased
(but never extremely pleased) but it seemed like there was something
in ACR that wouldn't get out of the way. Because I followed him since
my Quark days I worked out Bruce F's ACR approach for studio work but
it didn't get me there. I've read everything I could that Robin has
offered and believe that his explanations put light on some very
important things to consider. I've read all that Bruce L has offered
and appreciate his helpful ideas. Then came this RPP thing and it got
me hopeful again and a little stirred up about the subject.
It seems to me that regardless of the size of the audience there's
something valuable about the pursuit. Perhaps it may result in even
producing something of value for those who have no present interest in
colorimetric matching. Even if it's just hangar flying.
Henry
