| This formula is probably the ancestor to Microphen. I'd imagine that Microphen has more Phenidone and slightly different amounts of alkali and will develop slightly better film speed but all in all they should perform very similarly. Dilute this developer 1:1 for good quality, fine grain and a high degree of sharpness. | |
