Rob, Pardon my late response, but there's been such an avalanche of blather lately that some worthwhile posts are falling between the cracks.
Before C41 process came out, Kodak had C22 which was very stable but used environmentally unacceptable chemistry. AFAIK only Kodak films used C22, other brands had their own proprietory processes for colour negs and weren't interchangeable. When Kodak launched C41 in the 1970s most other manufacturers chose to come on board with C41 compatible films, rather than take the independent approach of the past. Consequently, the archivalness of colour neg films became more or less equal between brands, after a few unsettled years where C41 films would noticeably lose saturation and colour purity in as little as 12 months. regards, Anthony Farr ----- Original Message ----- From: "Rob Studdert" <[EMAIL PROTECTED]> > On 11 Jul 2004 at 21:34, Bill Owens wrote: > > > I've been using Agfa films, both slide and negative, since the early 1960's.
