Mick Fagan said:PE, does this mean that when I develop Portra films, I don't need to do the stabiliser bath?
As I sometimes develop Kodak and Fuji C41 in the same bath I would then use a stabiliser bath anyway, but if I'm only doing Portra it would appear that the stabiliser isn't required.
Or, is it a combination of the new films being manufactured differently along with the newer C41 processes having the stabiliser inserted in another solution(s)?

Mick;
I'm sorry but you really have to use the stabilzer designed for the specific film. At this point, I believe that EK and Fuji have diverged somewhat in stabilzer formulation and that EK is using a proprietary stabilzer.
This is particularly true of E6 chemistry where the pre-bleach contains some of the stabilzing chemistry.
There are comments on the respective manufacturers web pages, so I refer you to them for full information. There is also a recent post regarding this on PN. Dan Sapper, a product engineer at EK has answered some of this in detail and I don't wish to just cut and paste his comments out of the context of the entire thread over there.
