Dear Mark,

metrology point of view, as he puts it,

proprietary Adobe profiles
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.
