It might seem odd during a period of so much innovation and advancement in photographic technology deveooper a film developer formulated in the 19th century should be so popular with photographers and printers in the 21st century.
But the world famous Rodinal, at well over years in production, is just that. Formulated in Germany by Dr.
Momme Andresen, and introduced commercially inthe Para-Amidophenol Hydrochloride developer was first used in highly concentrated form for rapid development of plate films.
It was only when Leica cameras started to gain popularity in the s that the developer was also found to be very agva for giving high acutance and sharpness at much higher dilutions with the new miniature films… thus a legend was born.
Whereas many modem formulations claim to do one special thing or another, i. Most importantly it will give rodinaal negatives to work from with as much gradation of tone as can be reproduced on modern printing papers. Because the recommended dilutions for Rodinal are between 1: It also has an extremely long shelf-fife and loses none of its potency even when turning from its original pale straw colour when new to the colour of strong tea after a year or more.
Pros and Cons of Agfa Rodinal ?
One anecdote relates that a bottle of Rodinal, found in the ruins of a building in Germany after the World War II blitz, was perfectly usable after 30 years!
At the high dilution of 1: Average exposure and development would give a high contrast negative which would need manipulation at the printing stage to show shadow and highlight detail in the finished print. In the above image of the church in Market Lavington, Wiltshire, the contrast was high… strong late afternoon sun lighting the gravestone with the church in shadow and many mid-tones in the trampled snow.
It is not the finest-grain developer around but it does, at these high dilutions, produce extremely sharp grain and negative images with a real bite to work from. Because modern emulsions are much finer-grained than those produced years ago Rodinal now gives discerning photographers, both amateur and professional, printed results that were not possible when the developer was invented.
Flattery indeed… other manufacturers should follow suit. With different rolls being exposed to several subjects of different contrasts, this is still possible with APX and Rodinal if the developer is used at different dilutions. Because over-development, or an increase in developer strength, cannot appreciably raise the density of the exposed shadow areas in the region of lightly exposed silver halides there is almost nothing to actually over-developthe developer strength or developing time can be varied to lower or increase the highlight areas.
If the subject contrast is very flat the dilution of Rodinal can be reduced to 1: Both these developing manipulations should produce corresponding negatives with tonal ranges which have a ratio of 1: Negatives within this contrast ratio will produce good prints without manipulation and show a black, white and a balanced scale of grays in between.
It can then be repeated again and again with guaranteed results every time. Nevertheless it has many qualities that other modern developers have only recently caught up with. Rodinal is undoubtedly a classic in every sense of the word and the many photographers who continue to use it, or indeed who have only recently discovered it, never look back… their results probably speak for themselves.
