Where will B&W be in 5, 10, 20, 50, 100 .... years

Forecast the future of B&W.

Where do you think it will be in:

5 years?

10 years?

20 years?

50 years?

If there is enough participation the average of the
predictions often turns out to be pretty accurate.

They already do if you print using platinum and acid free
paper.

According to the Image Permanence Institute 500 years
is an acceptable estimate for an archivally processed
and selenium toned gelatin silver print as well.

Black and white silver imaging will always be practiced
as an art form. Plus in 1000 years when all those digital
files stored on hard drives and CDs have disappeared,
photos on film (any film) will still be here. Difference
between having a real bird in hand vs two cyberbush birds
that don't really exist to begin with.

Images from digital files can be archivally printed too. Why do you
think that photos from color film will be around in 1000 years? I've got
color prints that have already faded; there's no way they will last 100
years, let alone 1000.

Agreed. Color and BW printing (both traditional and
inkjet) are qualitatively different.

I'll put my money on pigment inks, but dyes are
inherently less stable. The only hope for dye ink
longevity is a very compatible substrate that can
prevent oxidation of the inks. I don't know how
one might prevent the breakdown of dye molecules
from simple photon energy. Gelatin and swellable
polymer substrates seem to be the key to dye ink
longevity.

I'm particularly interested in the archival qualites of color laser
printout. I have a feeling that the prints will last as long as the
paper, but I don't know with certainty. They don't seem to be impacted
by UV.

Those are _silver_ based images (assuming you're talking about
lightjets, etc.) Inks and pigments have to be sprayed. You're
mixing up a lot of terms and printing technologies here...

Bob, I thought this thread was about b&w...

_Film_ can easily last 1000 years, color or b&w. Ever hear
of transparencies? No digital file will ever come close; in
a 1000 years you probably won't even be able to read the
media it's stored on even if the data hasn't yet corrupted
(fat chance.) These issues and facts have been discussed ad
nauseam (at least in in r.p.dakroom), so I guess you just
haven't read the info. Plus, the very real likelihood/danger
is _all_ digital information may disappear (big article
recently in the NY Times on this...) except that diligently
maintained by the government (after all, they have to spy on
somebody...)

BTW, inkjets are not photographs, they're reproductions from
stored computer data. There is no photograph in the digital
process. It's all regenerated data (electrons - voltage -
digital signals - magnetic data bits - screen pixels) until
output as an reproduction from a digital file (i.e., drops of
ink sprayed onto paper.) Sprayed ink is not a photograph; it's
fancy newsprint

Now, when those repro images on fancy giclee newsprint have
been around as long as real silver photographs (almost 200
years and counting), get back to me and we'll talk about
inkjet longevity ;-)

I've got
color prints that have already faded; there's no way they will last 100
years, let alone 1000.

In fact, typical color dye prints today do have a display life
of at least 100 years. Color technology is more advanced than
when I'm guessing you printed those. OTOH, it's _all_ a matter
of storage and display with color materials. All color dyes,
inks, etc will fade if not stored or displayed properly. If
your prints have faded, I doubt it's the print's fault. I have
ciba's on my wall that look like the day I printed then 30
years ago.
