This is contrary to popular belief and the tests carried out?

There is obviously a lot of different opinions here because I have also heard a school of throught which says cibas will out last FB monochrome materials.....
Who knows what to believe.
I'm with Matt here.
I'll enjoy the aesthetics for now, and if my great great grandchildren get a mostly BW version, then it will be really cool and actually worth something!
I agree. I think it is widely accepted that Ilfochromes are stable. Any testing data out there is controversial, as it can only be accelerated testing, and therefore a "best guess" that is dependent on the assumptions made and technologies used. I only posted the comment to question whether it is the most stable color medium out there.

Ultimately, choosing a material to work with should primarily be based on aesthetics unless the material is known to be ephemeral, IMHO.
Also there is the fun factor!!!
Internegative films were discontinued years ago. 99.44% of printing of slides is done digitally, I'd say.
Dang! You guys are making me feel guilty, I've got a CAP-40 processor gathering dust and I just threw out an expired, unused 5-liter kit. I'm in the process of converting to B/W.
If I ever wondered if it was worth it, I would check out Christopher Burkett. I saw a couple of his shows, truely amazing stuff, ciba reds and yellows seem to
I have also heard that the azo dyes are extremely stable. Per Krause and Shull; "The expected life of unprotected Cibachrome prints under fluorescent or tungsten illumination is from 25 to 50 years, assuming that the lamps are operated for 12 hours a day. The permissible change in dye density ranges from 10% to 15%."**
They also claim that under museum quality dark storage,"...they'll have archival permanence. It is estimated that they will not change for up to 1000 years!"**

Recently I tried slides for the first time. Wow. I was very surprised. Exactly that are the results I never got with colornegativefilm.
For printing the best slides on paper, I finally decided to search a lab which does this job for me. Printing BW just is time consuming enough to me.
