Hello Edward,
in this sector, there are manly two guidelines: FADGI (American guidelines) and
Metamorphose (from Nederlands).
FADGI<http://www.digitizationguidelines.gov/guidelines/FADGI%20Federal%2…
suggests Adobe1998, ProPhoto or ECIRGBv2 while
Metamorphose<https://www.metamorfoze.nl/sites/default/files/publicatie_documenten/Metamorfoze_Preservation_Imaging_Guidelines_1.0.pdf#page=9>
only ECIRGBv2. I am not sure regarding the rationale of these choices.
So the first point is that ECIRGBv2 is the only one that is accepted from both.
I would like to use the large gamut of ProPhoto but because these master files will be
24-bit images (8-bit per channel) so using ProPhoto could result in posterization effects
furthermore is not well established.
Adobe1998 would be quite a good choice because of its larger adoption, but in the case of
manuscripts that have many red inks a larger gamut in the red I think could be
beneficial.
Regarding the equipment, we are deciding between some scanners e.g.
Metis<https://www.metis-group.com/product/drs-1300-dcs-heritage> DRS-13000 and Phase
ONE cameras.
Let me know if you think there is something I have missed!
Thank you for your interest!
Giacomo

Hello,
I am a technologist at the University of Verona, I am implementing a workflow for
digitizing the rare book collection of the Capitolare library in Verona. I am deciding
which color space to use for the master files of the digitized manuscripts. I am trying to
decide between Adobe 1998 and eciRGB_v2.
interteresting topic: what brought you to a decision between those two spaces, in
particular? if i may ask, what type of equipment do you intend to use for capture?
regards,
edward
I would like to use eciRGB_v2 but I can't find the specification of eciRGB_v2 on ECI
website, in particular how to convert RGB to normalized XYZ values, while the
specification of Adobe 1998 is available online and seems more documented regarding these
aspects.
I would like to ask you if eciRGB_v2 specifications are available for free? And if there
are any documents or guideline for the adoption of the eciRGB_v2 in artwork
digitalization projects?
Thanks a lot!
Best regards,
Giacomo Marchioro
