Rollei Digibase CR200 - Dwayne's refusal to process

[wogster]

Acetate slides can degrade after 40+ years, and convert back to vinegar,
but polyester slides will be around for centuries 1000+ years.

Polyester as a film base, has not been around long enough to know how long it lasts, it may last 1000 years, it may only last 20, nobody really knows. Funny thing is, I have an old B&W negative of my Grandparents, it's safety film, so acetate, it's also old enough to collect an old age pension. It has not been well stored, but acetate can last a lot longer then 40 years, if stored properly, and sometimes not so properly. Heck there are still millions of images on nitrate film, still in excellent condition, even though it hasn't been used since the 1940's, for still use.

PET base long term stability of at least 500 years has been proved by the Rochester Institute of Technology.
The YCM Separation Archival Master the way A.M.P.A.S define it is black-and-white polyester film stock.

This kind of testing, is called accelerated age testing, it could be right, it could be wrong, the only for sure way to tell, is to take a piece, let it sit for 500 years, then look at it. Realistically though, beyond my (potential) grandchildren, few people will care about my work, so if my images last another 100 years or so, that's good enough.... I have some 40 year old B&W acetate images, that are like new, so and like I said, an image of my grandparents is ~65 years old, and although it's grainy and the focus isn't great it was probably like that when new, they were farmers, so simple box cameras would have been the rule.

Once I had a roll of CR200 that had apparently jammed in the lab's machines. It came back uncut and wound on a spool. The film was crumpled towards the end of the roll. All other rolls of CR200 were fine.

10 Years after this thread and there are several PET Films on the market in 135. Has ANYONE experienced breakage feared? Any data, actual or anecdotal, out there? I haven't been able to find anything looking through forums and Reddit and the like!

No, Arthur, I have never heard of any serious problems or broken cameras in the last 20 years.
And I am using PET base films regularly for a similar time span (used it first in the 80ies, but not regularly at that time).
The only problems I've ever heard of were those with former Ilford HP5 "Autowinder" 72exp. film. They were documented as they were the reason why Ilford discontinued that film quite shortly after its introduction (see my post in the other thread).

Best regards,
Henning

My processor grumbles when I hand them PET film (color plus); he says their minilab can't cut the film and he must do it manually. Otherwise I like it, the thinner film slides thru my OM4ti easier and rewinds nice.
