Hi Brian!

      That's really smart to have 3 back media, but not many
do or will.  It's the same with archival analog.  The best way
to preserve a color image is to have it stored on 3 color
black and white separation negatives.  It's a lot of labor
and those who attempt it find that it's not easy to get
the color balance and registration but it can be done.
But once you have the three color separations negatives
it's child's play to make additional color prints, like
it's only really difficult.


      And about the twentieth centuries images, it's the
earlier part when black and white was used that's the
more archival, compared to the drugstore color prints
and all the slides except Kodachrome.  Will the geniuses
running with stream cease making it in a few years?  I
hope not!!  Kodachomre 25 died just recent.

I suspect that if I die before a truly archival technology comes along, my children will have no trouble reading any of the archival media and continuing this tradition of copying should that be what they want.
