Hello C. David,
thanks for your reply; I guess that according to your considerations, using Adobe RGB should be a good decision, also because I understand, it is easy a color space easy to handle.
However I heard that also Joe RGB, or the so called Ekta Space PS 5, Holmes, is a very good choice.
So, at this point, I will be very much interested what is your opinion, knowing that I represent a historical archive; I need to preserve my color images for very good color fidelity and gamut, but of course at the same time I do not want to create files and color space that can become not so easy to handle/convert/manage to my end users, end users that are from many countries and where they will use my images, later on, on various fields: pre press, home decoration, publications, poster reproductions, etc, etc.
So I need something with very good and accurate color gamut but at the same time easy to handle since I do not have too much time to spend in very selective color conversion. Thanks in advance!
Andrea

AppleRGB is not really a serious contender these days, and AdobeRGB has the

Its a balancing act that requires understanding all the factors and
