first c41 roll processed! wow! stab problem

danzyc · Jan 20, 2009

hello friend! it s very beautifull ! i have used tetenal c41 rapid kit!

after the processing i have seen that my stab is slightly pink....this would be no proper washing after blix???

could i reuse the stab? how many film could i make with this ?

when a c41 negative is not processed properly should i have strange cyan or magenta cast??

thanks for all!

There is a three minute wash between the BX and the STAB, so you should have got rid of all the BX. But there could be a little remaining. I wouldn't be concerned with a slight pink tinge, but would maybe use it only one more time.

This depends on the type of film, independent of washing time. I don't think you would notice the blix color in the stabilizer unless your wash had been less than a few seconds, and if so it would be brown. If you use a prewash as well you will notice this pink dye come out then as well.

I don't know what it is, but it is present in various amounts on most films and doesn't seem to be a problem.

If your stabilzer is pink, it is due to blix carryover. The wash was too short or the flow rate of water was too slow. If the stabilzer is pink, it has an iron based oxidant in it which is NOT good for image stability over the long run and also is not good for the formalin based stabilizers.

Myself? I would rewash and stabilze the film in fresh stabilzer after tossing the pink version!

If the temperature of the first developer was off, or you under or overdeveloped, it is possible that caused the color casts you are seeing. It could also be from the type of light the film was shot under. Almost all color films are balanced for daylight (5500 K). Using light of another color temperature can create color casts, and fluorescent and vapor lamps often emit an uneven spectra of light (more likely culprits in this case, assuming the film was developed properly).

I have the same problem - pink tinted stabilizer. I am using Kodak Flexicolor one shot in a Jobo processor following Kodak Z-131 for processing steps & times. Z-131 has no mention of a wash between bleach and fix. I increased the wash in a Wat-Air film washer at 95 degrees F to 12 minutes and I still get a pink tint to the stabilizer. I am processing Fuji films. I would think that 4x the recommended 3 minutes would wash all of the bleach & fix off of the film. Any ideas? Thank you in advance!

I use a wash after the bleach and one after the fix. I then remove the film reels and rinse with running watr using the Jobo film washer to do a final rinse. I no longer have pink stabilzer.

Having done image stability tests on film and paper, I know what this pink material can do. It will slightly degrade stability and cause an increase in the dmin. If you have pink stabilzer, you have a wash problem.

The wash between bleach and fix was in the original C-41 process.

I see the same thing in the presoak as I see in the stabilizer.

The presoak color is the absorber or acutance dye(s) added to the film to increase sharpness and trim speed.

The standard C-41 process program in my Jobo ATL-2300 doesn't include a pre-soak, although the outside of the tank is pre-warmed by rotation in the upper water bath.

Is there any way some of that could be left by the stabilizer? I only see the color with some films and my wash is fairly consistent.

I can't answer that without running tests.
