APH 09

APH09_NEW

 

Sharpness enhancing film developer

 

Manufactured acording to the ORWO R09 original recipe.

Rodinal is the world´s oldest photochemical patent. Momme Andresen first mixed this developer 1891 in Berlin and thus founded the photographical department of Agfa.

1945 Germany was divided and Rodinal walked off with a group of scientists and engineers to Leverkusen. In Eastern Germany the remainings of Agfa were converted into ORWO and Rodinal “east” was now called ORWO R09. It remained the most popular liquid developer in both parts of Germany.

Agfa in West Germany improved their Rodinal a few times and gave it better keeping properties and a slightly finer grain producing additive while R09 stayed more or less the same as it was in 1945.

This is why we offer two versions of Rodinal today. They are similar but not identical.

The developing times may be interchanged though.
