Kodak Portra 100 400

Marvin · Jan 3, 2011

I have some Portra 100 and 400 in the freezer from 2003-2004 and was wondering it it would need the old stabilizer or the new rinse. Some in 120 some in 35mm.

I'm interested too. I've ordered the Tetenal kit and have some expired in 2005ish Portra 160 and 400 and I'm wondering can I use the Stabilizer in the Tetenal kit?

either will work for film of that vintage IIRC.

I believe the change was made in ~2001/2002 from the use of "stabilizer" to the now-current "final-rinse" as the last step in c-41 processing.

Just don't use the final rinse with older films from before 01/02. It isn't backwards compatible. However, newer films can be used with either final rinse OR stabilizer, but its advised for "greater archival stability" to use the more current FINAL RINSE. It has added ingredients to aid with dye stabilization and better protectants for the gelatin emulsion(which is liked by bugs )

Portra is the first Kodak professional film of the generation not needing stabilization with Formaldehyde. Vericolor III is the last of the old generation.

Martin, you should have no problem since it has been in the freezer.

New films, like that Portra you have, work with Stabilizer or Final Rinse. Old films need Stabilizer. From what I have gathered here on A.P.U.G., what exactly constitutes a new film versus an old film seems to have more to do with design rather than with a certain cutoff date, and thus far, I have yet to see anybody post a list of which films are OK with Final Rinse. I do know that Portra is OK with Final Rinse and Vericolor is not, though. I haven't the slightest idea when it comes to Fujicolor films.

I think you mean old films need Stabilizer, not Final Rinse.

Thanks, and I have corrected the slip. I had it correct at the end, but wrote Final Rinse in the beginning for some reason. I have seven bottles of the Stabilizer stockpiled for use on expired film, so I shouldn't have done that....

As I recall, PE mentioned on a thread here that you can make stabilizer out of Final Rinse by adding a certain amount of Formalin. Not sure where that thread is at the moment though...

Interesting. So that implies that there is no need to add Photo Flo to the old stabilizer, it is already there?

Think about it, the stabiliser/final rinse has to be the last wet stage of film processing. Otherwise, if you used a wetting agent as the final wet stage, the stabiliser/final rinse would be washed away. So, it had to have a wetting agent.

I meant that I've read some people suggest adding some PhotoFlo to the stabilizer solution but that implied to me that there wasn't any in there already.

Stabilizer and Final Rinse both do their stabilizing stuff to the dye and act as wetting agents. They feel just like Photo Flo, though they smell a bit different.
