Rodinal Special is usually hard to find, particularly in USA. It is a better developer than Rodinal. Rodinal even diluted to 1+100 is rather grainy, to reduce the grain, people usually must add small amount of sodium sulphite as grain dissolver. Rodinal Special is Agfa's modified Rodinal, it produced finer grain then Rodinal + sodium sulphite. I use Rodinal Special for development of my Minox 8x11mm BW film ( Agfapan APX 25, Kodak Technical Pan and Ilford Pan F+ ) for enlargement of 25x to 30x. In fact, right at this, I just finish development of a roll of Technical Pan film taken at the ski resort town Whistler in British Colombia last week, the film is still in the fixer. For Techpan, I use 1+80 dilution, 20 degree Celsius, 15 minutes. Grade 2 paper level contrast.(posted 8511 days ago)
