Archival inksets for inkjet printers.
Don't know of any 200 year old photographs either colour or B&W, mainly
cause photography wasn't invented until the 1840's. But there are colour prints that are 100 years old and still looking good. Look up "Carbro Process" and "Autochrome." The Autochrome process produced prints before 1910 that are still vibrant today. http://www.institut-lumiere.org/engl...utochrome.html http://toosvanholstein.nl/greatwar/kleur/kleur.html Of course, for truly archival colour photography today one can take the camera original and from it create tri-colour separation B&W gelatin-silver negatives on glass plates processed and stored archivally. There are a number of top-ticket professional labs and museums that do exactly that. "Rafe B." wrote in message ... On Sat, 27 Dec 2003 00:08:36 -0700, Tom Phillips ....snip... May not outlast silver and gelatin, but with care can eaisily outlast most conventional color photogrraphic prints. So where are the 200 year old color photograhic prints and where can I see them? rafe b. http://www.terrapinphoto.com |

I believe one of Nicephore Niepce's photographs from about 1826 is still around, and he started work around 1816, and apparently got some results as early as 1819. That 1826 one will probably last "forever" as it is etched into a metal plate. -- .~.

Yep- sounds about right - date rounding error grin

Look up "Carbro Process" and "Autochrome." 1839 was the first "commercial" introduction of photography, not when photography was invented. The earliest extant permanant photograph dates from 1827 (Niepce.) Thomas Wedgwood actually made the first known photographic images about 1802, but didn't know how to fix the images. The first successful color experiements date from about 1861, and the earliest extant color prints (carbon) also date from the 1860s.

Have you actually seen any vibrant autochromes? I ask because the ones
I've seen look pretty pastel to me. The life expectancy of the common lab print - 99% of all colour prints being made today - is 20 years and a lot look pretty bad in only one or two years. -- http://www.chapelhillnoir.com home of The Camera-ist's Manifesto The Improved Links Pages are at http://www.chapelhillnoir.com/links/mlinks00.html A sample chapter from my novel "Haight-Ashbury" is at http://www.chapelhillnoir.com/writ/hait/hatitl.html "Steve House" wrote in message ...

Any organic dye will fall prey to oxygen and UV given enough time. Metallic colorants are quite stable, silver for instance. If metal salts were used for coloring an Autochrome's starch grains then the colors should last a long time. Red ochre (rust), calcium white (chalk) and bone black (burnt bone) have demonstrated lifetimes greater than 10,000 years. Not in the slightest affected by UV. I remember having Prussian blue (Iron cyanide), cadmium orange (cadmium sulfide), cerulean blue (cobalt/tin), cobalt green (cobalt/zinc) and a whole host of others in a paint set when I was young. The old stable pigments were still available from Russian art supply houses last time I looked. Or you can scrape them off the floor at a metal plating plant. If you want stable ink-jet colors, I am afraid EPA America may not be the place to find them. -- Nicholas O. Lindan, Cleveland, Ohio Consulting Engineer: Electronics; Informatics; Photonics. |

Look around you at nature - mostly pastel as well, with notable
exceptions. "Vibrant" does not necessarily mean the super-saturated colours of advertising photography and video game graphics. I think of it as meaning closer to "alive" and when applied to artwork as meaning "retaining the spirit of the creator as put into the work when originally created." A print by Weston or Cunningham is vibrant without any colour at all. "Tony Spadaro" wrote in message om... Have you actually seen any vibrant autochromes?

Then let me make it plainer. Unless they were always much paler than
reality, or the reproduction (in books that seem to get everything more recent correct) wis poor, there are a lot of really faded autochromes out there. Yes there are many pastel colours in nature, but there are many more in old colour photographs. -- http://www.chapelhillnoir.com home of The Camera-ist's Manifesto The Improved Links Pages are at http://www.chapelhillnoir.com/links/mlinks00.html A sample chapter from my novel "Haight-Ashbury" is at http://www.chapelhillnoir.com/writ/hait/hatitl.html "Steve House" wrote in message ...

An autochrome is made by attaching tiny red, green and blue filters to
the surface of black and white film, reversal processing the film (leaving the filters in place) and projecting the resulting colored slide. Polacolor (Polaroids instant color slide film) is a lenticular Autochrome process and is still in production. US patent 822,532 French industrial patent 339,223 EPO classification G03C7/08 describe Lumiere's original technology. Though they are rather vague on the fine points of sprinkling potato starch on pitch, as the manufacturing process had not been worked out when the patent was filed, what one man can do, so can another. As the process existed until the '30's it should be possible to find factory workers who still remember the details of the manufacturing process. The Lumiere company stopped making Autochrome in the 1930's. Lumiere was acquired by Ilford's parent company of the time, Ciba - of Cibachrome fame, in the 60's and merged with Ilford, long after Autochrome production ceased. Since the pigments in an autochrome are only used for filtering the light, any color absorbing material can be used, and the process is not limited to (generally) organic dyes that can couple with silver grains. There are many other color processes that do not rely on dye couplers, the most common being 4 color lithography; another common method is ink jet printing. There is no technical reason that metallic pigments can not be used in an ink-jet printer. OTOH, the color gamut of metallic compounds is fixed and the accuracy of color reproduction will be reduced -- but this limited color gamut serves painters very well. -- Nicholas O.
