I think at the moment where we are entering a second dark ages due to digital we need to make sure what we do will survive. This isn't a dig at the digi's but from many years experience in IT digital prints have never lasted more than a few years and RC at the moment is still unproven. If any pictures of our current times are to be guaranteed to survive then proven materials need to be used. Hope that makes some kind of sense, my brain is getting tired.
