Rodinal has a very well-deserved reputation for brilliance, gradation, and sharpness.
WebbThe precursor method achieves mixing at the atomic level by forming a solid compound, the precursor, in which the metals of the desired compound are present in the correct stoichiometry. For example if an oxide MM 204 is required, a mixed salt of an oxyacid such as an acetate containing M and M in the ratio of 1 2 is formed.
