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. -- Nicholas O.

They already do if you print using platinum and acid free paper. -- LF Website @ http://members.verizon.net/~gregoryblank "To announce that there must be no criticism of the President, or that we are to stand by the President, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public."--Theodore Roosevelt, May 7, 1918 |

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. "Nicholas O. Lindan" wrote: Forecast the future of B&W.

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. Bob |

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. rafe b. http://www.terrapinphoto.com |

I don't know how 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. Bob |

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... |

Why do you think that photos from color film will be around in 1000 years? 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. |
