If you are doing reproduction work and like for your colors to match the original, you choose the profile that gives you the colors that you like.
you were going to say "you
build", right ? because you need to build something before you choose something as there is nothing to choose from really...
we discussed recently how to expose the target and Eric Chan recommended (to get the highest quality profile) simply : 1) bracket 2) select the most exposed/ETTR'd target that still will be accepted by DNG PE - basically just trust some internal checks that Adobe put there...
now if we are building a profile for reproduction using some dcp profile building tools (DNG PE, Xrite or QPCard, may be I missed something), what shall we do ?
1) we shall not build any dual illuminant profiles for sure - we shall build a single illuminant profile for reproduction purposes, right ?
2) what about light - shall we use the light of the intended illumination (where the reproduction will be displayed - if we know that of course) ? shall we use some high quality standard light regardless ?
3) certainly such "reproduction" profile is just a part of the whole process, hence a question - are there any special considerations that must be taken (while preparing such profile) into account about further raw conversion (ACR/LR), possible postprocessing and printing ?
4) what are the checks that are possible (if possible at all) early in the process to understand if we are close to possible perfection (I mean as early as possible - not when we actually print a copy of the work being reproducted to compare visually or w/ some tools with the original) ?
I mean if that is a reproduction it shall not depend on what you like or not like... the shall be some dose of a formal approach.
