Response to Will I get finer grain if I have more metol and less hydroquinon in D-76?

I seem to remember that the original D-76 was formulated to give the optimum Metol/Hydroquinone ratio for maximum superadditivity effect. This means that it has the highest activity for the least amount of developing agent, and therefore gives the fullest film speed compatible with fine grain. Altering the ratio may well give finer grain, but you'll almost certainly pay for it in terms of film speed, gradation and development time.
