Hello everyone,
I’d like to develop my very first roll of film and have already read up on the subject extensively and sought advice from friends. Today, the Rodinax 60 I bought at auction arrived – a fine piece from the 1950s. However, the chart included regarding films, developers, etc. is correspondingly old (my instruction manual is in English).
Of course, only Agfa products are listed, so I’m unfortunately stuck with my Ilfosol and Ilford FP4. For example, it states Rodinal 1:75 / Isopan ISS (100 ASA) = 14–18 minutes at 20 degrees. How do I work out the corresponding Ilfosol figures? Should I simply go by the specifications (mixing ratio/time) on the developer? Or even better – does any of you have experience with the Rodinax 60 and can give me some tips and help regarding chemicals and times?
I’m not sure now whether I’ve perhaps asked a ‘silly’ question, as I’ve really never done any development before. But I’d love to get started right away :-)
Best regards, Maike

You can find the development times for Ilford products here:

I don’t think the development times in a Rodinax 60 canister differ from those in a ‘modern’ canister – just give it a go...

I'd be interested to know that too – do they calculate it based on the tilting motion or the rotation?
Regards, Woifi :D

Hi, I’m also interested in the Rodinax 35.

Hello,
I’m only vaguely familiar with Rondinax bottles.
In principle, however, it works like this:
- ‘Tilting’ means that the spiral is moved vigorously through the liquid for a short time (or the liquid is swirled around the spiral), followed by a longer period of rest, and then it is moved again at the start of the next interval (30 or 60 seconds).
- Rotation is a relatively steady, continuous movement.
So, if you only move the spiral briefly once per interval, you are tilting; if you keep turning the handle continuously, you are rotating.
The times are usually just guidelines to serve as a starting point anyway. The best time will then emerge as you carry out your ‘trials’.
Swinging regards,
Henning

Hello Maike,
I use a Rondinax 35 myself. The development times for Rodinal developer listed in the table are fine as they are; I think you can leave the others as they are for your first attempt too. With the Rondinax cans, it’s important not to rotate them continuously. The instructions say to give a third of a turn every 1–2 seconds, in short jerks in the direction of the arrow. It doesn’t matter that part of the spiral is always outside the solution; other developing machines like the Colenta or Metorette work the same way.
Best regards, Jürgen
