I am trying to put this all into context for color balancing digital photos
and art, to be "printed" via A] a traditional EP2 lab{RBG} and B} offset
lithography {CMYK in brochures,catalogues,etc.}. At this point I am not
relying on the monitor to see color{ I have a spyder package on order} but
rather the RBG/CMYK values of the GretagColor Checker. I will expand my
questions for a moment based on the above:
1.I should assume then, that I should be handling the images in the color
spaces relative to each of these output suppliers.
...if so, in capturing the image, should the initial capture{digital} be
handled and saved in these respective space..and/.or is it of any
consequence to capture and save the file in another space and allow
photoshop to convert it?
2. Although I have not tried this, would it be of benefit to capture & color
balance the images in LAB mode...and then convert to there respective
spaces?
3.I understand that any defined SPACE represents different gamut of color{I
think this is a correct statement} but why doesn't the SAME color{ie. from
this chart} have any absoulte value{color temp?,etc} that represents itself
in all platforms? How can OUT of Gamut colors be "defined" if their readings
are different in various spaces? Other to say that this given space cannot
reproduce this color...it still must be defined in some absolute, meaningful
cross space manner.? I am still having a hard time understanding how a grey
value of 30/30/30 {for instance} will or even should be different depending
on the working space.
4. In attempting to color balance these shots, what would the consequence be
of manipulating/retoutching the shots prior to conversion to the final
working soace? I have been converting the CMYK shaot BEFORE i do any
manipulation
