tetenal
I have done it again , I have bought something I have never used before and its got me confused (that's not hard)anyway bought a bottle of Tetenal ultrafin negative developer and I cannot understand the instructions ,for example I want to develop a roll Ilford FP4,1x10 dilution ,there are two dev times A and B , A says 5min and B says 8min,then at the bottom it says inversion agitation rhythm A=3sec. B=1min. I have always agitated the last 10seconds of every minute .any help ???.also whats it like is it any good ,I would like your opinion as well as your help..PS I have just looked at the massive chart for HP5 and it says continuous agitation at 4.5mins now I am stumped...

I couldn't agree more Paul!
If I were you, I would go with the times in the Ilford data sheets which states 7mins 30secs HP5 and 7mins for FP4. I would do agitation as you do normally and go from there. And the products I've used from Tetenal, I've been very pleased with. Ilford data sheet links www.ilfordphoto.com/Webfiles/20106281054152313.pdf www.ilfordphoto.com/Webfiles/2010712125850702.pdf

thanks Marty I had a look and took some notes I have been looking at other sites for other film dev times ,these are the films I am using at the moment and the developing times I have found HP5=7mins30sec.. FP4=7mins.. Tmax 400=7mins... Fomapan 200=7mins30sec ... . And all these times are with Tetenal ultrafin , diluted 1x10 at 20c .
I have put the Ilford site on my favourites ,I did not think of looking there ,its funny that all the times seem similar just 30sec different. I can probably trust the Ilford times but not sure about the others.. www.essexcockney.com |

I wonder what the explanation is? Maybe our German friends whose command of English is superb can help? I am curious about this matter now. Mike |

I always use my standard inversion method no matter what film developer I use apart from PMK Pyro and it has not let me down. When in doubt stick with what you know.

Tetenal
I have found a few anomolies with Tetenal in the past. My last encounter with a 'strange' instruction was with one of their E6 kits where the 1st development time for E6 film was, if I remember correctly 6.5 mins, but if it was a film made by Fuji then it had to have a 5% increase.
This was just after the reintroduced Agfa Precisia hit the shops - was it a Fuji film in disguise or made elsewhere. At the time no one would or could say with any authority so I processed it as a non Fuji film and it was fine. |

The answer seems to here:
https://www.fotografie-in-schwarz-we...-bewegung.html Paragraph 4 talks about inversion rhythm (kipprythmus): 3 sec. rhythm means once every 3 seconds 1 min. rhythm means continuous for first 30 sec., then 3 times every minute thereafter. I looked through the Tetenal data sheets and there is no explanation of this at all in the German text. I presume this is the same tech doc you were referring to: http://www.tetenal.com/imaging_shop/images/00001809.pdf Table 1d....right? Hope this helps. Let know if you need any other translation Cheers, Svend |

One inversion every 3 secs is a little less that continuous agitation speed on a Jobo processor so maybe that accounts for the difference but my "gut feeling" still says that if 8 mins is correct for inversion type B then 5 mins for inversion type A might leave negs a little thin We need someone to try both methods and times. Any volunteers? Mike |

Interesting that this is written in a general guide to developing technique, and not in Tetenal's literature. And that it differs slightly from methods in the English-speaking world. Makes one wonder how the method came about in Germany - as generally accepted practice by the community, or from manufacturers like Tetenal? Maybe our German friends can tell us... Me, I'm just a transplanted German living across the pond .

thanks for all your help ,you would think that Tetenal would put some times to some films Ilford do , and Ilford's times are quite good ,this has surprised me ,but I will try it and see how it goes. the problem at the moment is as I haven't been well for a while and I haven't been out on my disability scooter to shoot any film ,but I am having a birthday party this Sunday at home so I will take some photos then ,its the big sixty ,at lest I get my medication for free . more money for film.:-)
