tetenal c-41 doubt

[voland]

hi,

I have bought a "tetenal colortec c-41 negative kit rapid", but there's no clear instructions about how often do I rotate the tank during the development in manual mode, I don't have any hobo proccessor.

thanks for your help in advance.

cheers!

I just used the agitator stick and go as constantly as I can keep up for the 3min15seconds. A *j*obo processor is constantly rotating so that's why I try to just go for as constant as I can.

Voland,

The manual agitating procedure for use with small tanks is to be found in some of their tech sheets (at least in the German ones):

For E-6:

-) constantly for the first 15sec (1.dev, c-dev, blix)

-) one tilt-cycle every 15sec


For C-41:
(They only state it for the tablet and powder kit, but should be apt for the liquid kits too)

-) constantly for the first 30sec (c-dev, blix)

-) one tilt-cycle every 15sec


Keep in mind it's not about a rotating maneuver but a `tilting the tank upside down and back´ cycle (like you most probably do when processing traditional b&w films).

I now use a Jobo for my C-41 - I find it much less hassle than inverting the tank by hand.

Before I got that, I used a small tank in a water bath, and inverted it once every 15 seconds. The results were as good as they are from the Jobo, but a lot more hassle

[voland]

thanks a lot for the information!
I'll try one tilt-cycle every 15sec.

only one more question... do you use Stop bath before the Bleach Fix bath ? I think this is optional.

[AgX]

Tetenal does not refer to a stop-bath in their C-41 processing schemes (E-6 employs rinse steps), but states in the text that for C-41 a stop-bath would give greater security against failures of the Blix, in case the latter should be re-used for a next run.

[Akki14]

If you use a stopbath, make sure it's at the same temperture as everything else (obviously) and keep it only for c-41. Don't mix it with your B&W stuff, just to be on the safe side.

If you use a stop bath, be sure to give it a quick wash, especially if you use the "blix" (bleach-fix) hack.

Also, if you use a separate bleach & fix step, don't use the fix for B&W film after it has been used for color (C-41 or E-6), since contaminants (I forget which) will affect the longevity of the B&W film.

Tip of the hat to Photo Engineer, who gave me this warning last year.

I thought the fix for c-41 was a completely different chemical than for B&W fixing ... I don't know, I have blix which is scary red and i'd never use it for anything but its intended purpose.
