Finding no source in the US for several of the chemicals needed for making the developer recommended by Orwo (e.g. pentasodiumtriphosphate), I am wondering if anybody has used D-19 for reversal processing of Orwo 54 film. I use Lomo and Morse tanks for 16mm. I need suggested development times as well as some comment on the quality of results. Or perhaps someone has used other developers such as those suggested by Ilford and can provide time required for first developer. I am asking about home processing only since after laboriously gathering together all of the elusive chemicals required for developing Kodak 7266 I decided that the 60sec times are possible only with machine processing and went back to using D-19.
