bljkasfdljkasfdljskfa Posted February 14, 2006 Share Posted February 14, 2006 This developer turns dark-ink-blue used with HP5+ and Neopan and darkgreen with Fortepan, etc. Xtol didn't do this. I know it's harmless,but just curious what kind of chemical reactions happen. Link to comment Share on other sites More sharing options...
jay_de_fehr Posted February 15, 2006 Share Posted February 15, 2006 Hi Dan. PC-TEA is sulfite-free, and sulfite clears many of the AH and other backing dyes which can color the used developer. Jay Link to comment Share on other sites More sharing options...
jordan_w. Posted February 15, 2006 Share Posted February 15, 2006 Jay is right. You are seeing the anti-halation dye present in many 120 films (not sure about 35mm). In some developers they "come out" visibly tinted, in others they don't. It's probably the sulfite and the alkalinity that matter. Link to comment Share on other sites More sharing options...
chris_waller Posted February 15, 2006 Share Posted February 15, 2006 Ditto the above, it's the A-H dyes dissolving. In some films the A-H dyes wash out (even in a plain water pre-soak), in some they wash out in the alkaline dev and in some they clear in the fixer. I had one film which turned Jacobson pyrocat deep yellow. Link to comment Share on other sites More sharing options...
