C-41 troubleshooting

[markbarendt]

Yeah, its unnecessary if you use the normal kodak bleach. I'm just too poor to buy the real stuff.

I don't know what you consider expensive or where you live but it looks like for about $60 bucks plus shipping you can get 2x 2.7liters of Kodak's C-41 SM bleach at Liberty.

Just found Sonman. http://www.sonman.com/products/KODAK...n-order-2.html even cheaper at about $41 plus shipping.

That should be enough to do about 800 rolls if I read the Kodak's instructions right.

I have always used a prewet in my Jobo. This has been my practice for years and I get on-aim results, I assure you.

Kodak specifies pre-wet for C41, but not E6.

Seriously, eBay bargain bleach is the way to go.

I've been looking for a while but I've been unable to find any.

The lowest I've found previously was a little over $100. I seem to be bad at googling. Thanks.

Nicholas,

See the Kodak pub on this: http://www.kodak.com/global/plugins/...ls/z131_03.pdf

"Adjustment. Do
not immerse the film in a warm water pre-soak. Warm-up step is
done by warming the outside of the tube with hot air or in a
tempered water bath.

Sorry that must have been the Tetenal C41 sheet I was thinking of. I've always used it.

No you are not bad at Googling, don't fool yourself it took a significant amount of time to figure this out.

The biggest frustration I have with C-41, is not the process; it's the mystery and myths that surround it.

We end up doing chemical back-flips like you were trying from a simple lack of knowing what our options are.

P E: I have used Digibase C41 for a long time. Now im having a big batch of Flexicolor LORR Replenisher developer ill try to match Digibase. First i mix one litre replenisher solution who then is mixed down to tank solution with water and starter. Used in a JOBO for 3:15 6 min bleac (RA) Then C41 RA fix. All wash cycles.

I have done some densitometer readings. Looks like i add to much water, but following KODAKs advices from their tech pub on it, Can you see out from my added curves whats wrong?

The density readings are from machbet/x-rite colorscheckers neutral steps.

[Photo Engineer]

I cannot begin to evaluate this spread sheet. It is totally alien to me in overall format and content. Sorry.

I'm not sure what the problem is, if any. I don't know if the Digibase results are OK or not for starters, and then by comparison IDK what is wrong with the EK kit.

What I need is a plot of Density (y axis) vs Log Exposure (x axis) for each process. This will clearly show me dmin, relative speeds and contrast with crossover.

Thanks.

I have purchased from Liberty and can say they are a good place from which to obtain these chemicals.
