Tetenal E6 kit

[rowghani]

Whats the most amount of rolls you've gotten out of a litre of mixed solution? The manual says 16. Anybody gone higher?

Follow Tetenal's directions. They know more about their product than anyone else.

I was thinking of E6 before and at the end I have decided to let it do a local lab regardless the price they ask and the time needed to wait for.
My impression was that E6 is a slippery slope unless you do exactly as it prescribed by the manufacturers.

So I would not go over 16.
Also look seriously at the self life. For E6 its horrendously fast.

My current tetenal e-6 kit is 2 years old. It means I've unsealed it 2 years ago and I still use it. I reuse each batch 4 times. That yelds 16 rolls. Manual says 12.

i have never used the 1l but have used many of the 5l kits and have gotten the prescribed 72 rolls from it, so I guess that means about 14 rolls per liter. I have no need to go more as quality is much more important. no difference between roll 1 and roll 14.

i also have kept the concentrate for over a year, I usually mix 1 liter at a time. i have had no issues with concentrates with 16+ months bottle life giving perfect results.

I do 6 rolls per 500ml so 12.

I recall weeks for the self life of the diluted working liquids.

16 should be right with no push pull processing involved.

Long-term storage of open concentrates

To JaZ99 and destroya: How do you keep the concentrates for so long? I have issues with the kit: The FD forms crystals, starting after some 6 months the latest (and growing slowly and steadily); the Blix part 2 starts yellowing (sulfur) after 6-8 Months; both strictly kept under protective gas (original Protectan, since 4 ys camping or ronson gas). None of the 5 5L-kits I've used so far remained usable for a full year.
Re. reuse: My experience: 1 immediate reuse is ok (with fresh solutions from ok concentrates!); storage between uses and even another 3rd use as suggested by Tetenal is already stretching things to a point where some may not be happy anymore with the results. I don't think I'm alone with this observation. (BTW, Tetenal now advertises 12 rolls/L; a whopping 16 rolls was years back in the olden days - Kodak and Fuji cautiously limited and limit their suggestions to 10.)
Would be glad to learn how to keep this expensive stuff a bit longer!!
Cheers, P.

I've gotten 16 with fine results and a friend of mine says he gets 22 from 1 litres. I do shoot a lot so the solution doesn't sit there for too long.

The trick is to pour enough gas to remove the oxygen. 10-15 seconds at least. And I use the silver-gray waterproof tape to re-seal the bottle.

I simply develop 4 runs day after day over the weekend. And I protect the chemistry with the gas, too. And I use lab grade bottles designed for storing chemicals (those with wide opening and secondary cap under the main cap).

 

[destroya]

i use propane that i get at home depot. Like jazz I use a little more than necessary to be safe. I store in a place thats dark and cool and it seems to work fine.

Thanks for your notes! Doing the same things - no idea why in my place the stuff isn't that fantastic. May be thin air at above 6k feet???
Cheers & good light! P.

This is good to hear. I am thinking of saving some dough on processing by going the Tetnal 5L route to soup about 70 rolls of Provia 400X from a single trip to Cuba in May. I will be using my Jobo CPP3 and might be pushing some of it no more than 1 stop.

How does this kit do with pushing?

Also, it has been awhile since I have souped E6, outside of the included chemistry, what other steps do I have? Not too concerned with chemistry shelf life since this will all get done in one weekend.

I would test myself with a smaller volume first.
I cannot think of color processing as anything to do with pushing.
How would you hang 70 rolls over one weekend?

Absolutely on the testing first. I am betting pushing will be fairly straightforward as the CPP3 has it pre-programed, just want to know if the chemistry does well with it. Drying not a problem, I have two Jobo Mistral drying cabinets.

For me pushing means some level of degradation for an arguable benefit of a single stop whereas slides are more for perfection.

 

[destroya]

ive pushed provia 400x in 120 up to 1200 with no issues whatever. works fine. just follow the directions.

Perfect, that is the answer I was looking for, thanks!
