Dear THomas
I have been wondering if the original Bruce Frase method( Creative Pro )
could be applied to asignning a profile other than Pro Photo and still get
good results. THe values for the Macbeth seem to come from the Lindbloom
tables of values ( excel tables available at his website), but I am not so
sure if just running the test with , say, Adobe 98 or ColorMatch would
provide equivalent results.
I may understand he is just working with the widest color space available
in Camera Raw, but from the comment above, I would tend to think this is a
reasonable way to test and get "pleasing" results in other color space?
Also, if you don't mind my asking I would like to know if you have any
comments about the rather "light" black point settings suggested by
Lindbloom in his tables. I find that if I ever use his recommended settings
for blacks( around 40-50) I would never get rich blacks in the printed
results,(something I could verify precisely while shooting Art Work),
although I might get very very close to all his other Macbeth color patches
values under working conditions, both in Adobe 98 and Color Match.
Thanks
