As far as I can figure out, although I may not be up on the latest.
Apologies if I'm wrong on anything.:
HABS quality, black and white archivally processed fiber based paper and
archivally processed negatives:
There are negatives and prints 100+ years old - proven archival.
Average black and white prints, not HABS type - I understand that machine
processing usually doesn't rinse B&W enough. RC paper may be holding up fairly
well archivally by now, since it's been around for a while.
Note: It's becoming harder and harder to get supplies to take and process
these. Almost *all* the photography stores are closing. I may have to order by
mail from New York.
Color prints:
They will fade eventually. I don't know the latest. Your best bet is
probably Cibachrome prints from slides, more expensive.
Color slides:
Kodachrome has had an edge on Ektachrome. Ektachrome has gotten better in
the last how many years, though. I don't know about the new slide film with
different ASA ratings (some research needed - I'm always suspicious).
Digital computer files:
How many of you can read a 15 year old file on a 5.25 in. floppy? My Win 98
computer won't read a Win XP CD, although there may be a program that will let
me do it (I haven't looked for one). It takes the CD into the drive, tries to
read it, and spits it right back out. I can read them on an XP computer. It's
not the program but the format of the CD.
In even 10-20 years, are we going to be able to read and print the files
we're making now? Are we going to continually redo *everything* in the archive
with each new format? Which of the picture formats now available do we save
them in now?
Printers:
Laser on archival paper is supposed to be archival but they print terrible
photos. Laser is, I believe, powder not a dye.
Inkjet - see previous message.
Basically, dyes tend to fade. Silver negatives and prints, Laser type prints
and copier prints hold up if the paper is archival because they're not printed
with dyes. Film (slides and negatives) using dyes, will probably fade. It does
look like they may eventually be making the dye processes a lot more archival
and some aren't bad now.
