Agfa Rondinax: how to use it?

greenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread

I have find an old tank for the development of the negative of the Agfa: the Rondinax. Someone can explain me how to use it and the amount of the liquids to use ?? (sorry for my bad English!) TIA

re; Agfa Rondinax: how to use it?

Is it Rodinal or Rodinax.

I use Agfa Rodinal, a 100 (ore more) years old formula, but in an unconventional way. Used as recommended by Agfa - produces high graing but excelent tonal range.

If it is Rodinal - I will share with you my technique.

Rodinal

I would like to know what your technique is.

...hem...sorry, but the Rondinax is an old tank, not a chemical.

I have used Rodinal exclusively since the middle seventies. Thanks to Bill Pierce here is the formula that works for me. For normal contrast negatives: Dilute 1:75 add approx 50grm Sodium Sulfite

I should have added to my note about Rodinal and Tri-X that this combination gives an Exposure Index of 400. The above formula is for normal contrast negatives. You can lower contrast by changeing the dilution to 1:85, or increase contrast with a dilution of 1:50. Development time remains 11min. 30sec. @ 68 degrees. For an Exposure Index of 800, dillute 1:50 and increase development to 15min. @ 68 degrees.

Sorry to continually refine my answer, but I want the answer to be compete and usable. I normally develop 2 rolls of film at a time. The 50 grams of sodium Sulfite is for 2 rolls of film. i.e. use about 25 grams of Sodium Sulfite per roll of film you are developing. That's all, honest!
