Dear Roger,
CC24 is a standard Macbeth ColorChecker chart with 24 patches.
I have an enormous backlog right now due to the summer spent mostly
shooting on different locations. I will make a report on the route I
tried, probably in October.

Hi Ilah,
That's interesting. Could you sum up your chains of processing in
the form
of some test images and screen captures so that anyone interested
could
reproduce your results? If that does not take too much of your time,
of
course. I'd really like to replicate your findings here.
What does "CC24" mean, by the way?
Using ProfileMaker 5.08 to generate a custom profile for 1DMkIII (the
only Canon dSLR I currently have) I shoot Hutch target and processed
the shot through C1 using that profile. I also processed the file
through dcraw -h and assigned the profile to the output. Next, I
processed the file through LR with new beta profile. Then I generated
a profile for ACR from a shot of CC24 and processed the shot of Hutch
target again, through LR with a new custom profile I made with Adobe
profile editor. Comparing delta E on the results is a wash, and for
many patches with L<30 and L>70 colour and tone were distorted to the
point where I think it is not acceptable (my personal taste, of
course).
Finally, I used LR with the new custom profile from CC24 to process
SG
target and created a profile from the LR output in PM 5; then I
processed the shot of the Hutch target throw the new chain of my
custom profile for LR and assigned PM 5 profile to the output. That
rendered pretty good results, delta E was less then 6. Forgetting for
the moment noise and sharpness issues, this route may be useful.
