On the other hand, this also means that Adobe, with its
proprietary technology, still can't improve on the best Canon
factory profile, which, as you might remember, is a standard
ICC profile.
I never stated that *profiles* "can't improve". The subject in the
first quote above was *Adobe*, and the quote refers to the fact
that of all Adobe default profiles, none is (metrologically) better
than the best Canon default profile.
So Adobe profiles still can't improve on the best Canon factory
profiles which happen to be standard ICC profiles? Yes or no?
Profiles are no subjects; they cannot "do" anything by themselves.
Adobe is a subject and can try to build improved profiles, just as we
can.
Based on my assumption that *Adobe* would showcase the best *they* can
with their default profiles, they (Adobe) obviously can't (i.e. none
of the default profiles Adobe delivered is better (metrologically)).
That's no contradiction to the fact that the profiles are editable and
therefore, potentially, improvable by whoever will try. But that has
yet to be done (or at least made publicly known).
And all other Raw converters can't utilize the DNG profile editor.
True enough. Again, had Adobe sticked to the existing ICC standard,
they'd have delivered a profile editor instead that now everyone could
use.
They have to spend THOUSANDS of dollars for a target and software if
they want to build or edit themselves profiles.
Not so. Assuming you own X-Rite's new and excellent i1 XTreme package,
which at Euro 1500 (don't know the Dollar price) almost anyone
interested in color management will, it will cost you some Euro 250
for a Digital ColorChecker SG, and that's it. You might even get by
with a Wolf Faust camera target for Euro 15.
If you own an i1 Pro, but not X-Rite's new package, you'll need to
spend an additional Euro 230 for the i1 Match camera profile module.
They have to spend hours setting up complicated lighting just to
shoot this target. So the shoe as they say is on the other foot
here. The DNG editor is free! Its real easy to use.
I think this is a matter of preference (so again, choice would be
good). I certainly did not need hours to set up the target lighting,
but of course that depends on the equipment and experience you have.
In any case, it is correct that this needs some effort. Once you've
done that, however, profile generation is automatic and a matter of
minutes.
Editing a profile manually, on the other hand, avoids all the effort
of shooting a target, but needs more effort and time when manually
tweaking the profile. So, assuming both procedures can achieve results
of similar quality (I simply don't know, but let's assume it for the
sake of the argument), it's, as I said, a matter of preference.
Personally, I'm the type of guy who cannot stop until he thinks
something is perfect, and since I can hardly ever be really sure when
editing a profile manually, it would probably drive me insane, whereas
I have fun shooting a target. I'm a physicist, so dealing with
experimental settings and measurements is second nature to me. But of
course it's perfectly legitimate to feel exactly the opposite way.
Again, it all about choice.
Yes, I would have preferred if Adobe sticked to standards, but they
haven't, and now that they've established their own profile format,
I'm certainly not lobbying to take this back.
All I'm saying is it would be nice to have a *choice* and therefore
the *option* to also use ICC camera profiles in Lightroom (or
Aperture, for that matter). Then Lightroom users could decide whether
they, as individuals, prefer manual tweakings or measurements.
Alternatively, enhance the DNG profile editor so that it can use the
Digital ColorChecker SG (or another high-quality target) instead of
the 24 patch only ColorChecker, and achieve results comparable to
ProfileMaker.
