The ultimate point I'm trying to solve here is - is there any point in scanning printed photos with a wider gamut than sRGB?
I'm assuming such as standard analogue Kodak negative film printed to appropriate Kodak paper. Is this anything like CMYK or is it something entirely different?
Is the gamut similar to CMYK even if the process is arrived at from a different direction?
Side question: Does this also apply to slides, positives?
My google-fu has failed me on this, as everything I find relates to 'modern' printing from digital to inkjet, giclée, laser etc, so any search I try is buried in modern structures.
