Rodinal black and white film developer was patented by Dr. Momme Andresen in 1891. Rodinal was the first product produced by Agfa and the oldest continuously-produced developer formula in the world. Formally manufactured by Agfa, it was sold to Connect Chemicals (Ratingen, Germany.) in 2008.
It’s a one shot liquid developer usually used in high dilutions of 1+25, 1+50, 1+100, 1+200. My favorite dilution/film combination being 1+100 using stand development (no agitation) for 50 minutes.
It has a very long storage life, mine is over 2 year’s old and is still producing great negatives.
It is usually suited to low film speeds based on the high acutance properties and the coarse grain this developer produces. A solvent (such as sodium sulfate) can be added to soften the granularity. However, I find that films shot at high speed such as Fuji Neopan 1600 and Kodak Tri-X (rated at 16000 iso) look beautiful.
A must try for anyone interested in black and white film development and a great starting developer for anyone thinking of developing their own film.
It’s readily available to buy in the UK with an average price of £12.
