I am trying to figure out how to under develop with rodinal. This has a very specific application and it will not be for all, most, or some circumstances. I use semi stand development with reasonable success. I have been using increasingly dilute solutions but still have not crossed the threshold at which the film becomes underdeveloped. Currently I am experimenting with 3ml Rodinal to 1000ml H2O for 1 4x5 sheet. This yields a normal development. I have tried developing 2 sheets in the same dilution and yet again the result was normal development. Does anyone know the absolute minimum amount of Rodinal per 4x5 sheet?

I am trying to restrain glaring highlights, an extremely dilute solution may achieve the results I am looking for. My next step is to try 2ml Rodinal to 1000ml H2O.
