For many years I used Rodinal for medium and fast speed films by
diluting it with a 7.5% solution of sodium sulfite instead of water.
Developing times were reduced by approximately 20%. Grain and gradation
were improved.

Formulary Paraminophenol is a p-aminophenol hydrochloride film
developer that is economical and excellent for slower speed films (ASA
32-200). Unless graininess is desired, Formulary Rodinal is not
recommended for faster films. Formulary Rodinal produces very good
sharpness, high acutance and fine grain when used to develop modern,
ultra fine-grain emulsions. The contrast is variable and depends upon
dilution and development times. The chemicals in the kit are used to
prepare a stock solution, which is diluted 1:50 or 1:100 to yield up to
100 liters of working solution. The shelf life of the stock solution is
six months. The working solution is used once and then discarded.
Because the developer is used at very high dilution, it has a
compensating action that prevents blocked highlights and brings out
shadow detail.
This is an old Agfa formula but we are uncertain how similar it is to
the most recent liquid version they had out. As with all new developers
we recommend that you do your own tests.
