    APX + Rodinal: Exit Color

    I've noticed that whenever I process APX in Rodinal, be it 100 or 400, I get a very dense eggplant colored solution when I dump it out. This is not new news by any matter and it doesn't concern me. But the reason I throw it out there is that I noticed I rarely get this level of purple/pink/etc. with APX and other developers. I can't remember D-76 nor XTOL ever giving me the same overall purple vibe even after fixing, washing, etc. - and dev solution is always clear/yellow-tinge. Even during each wash cycle I do not get an overall purple tinge to the dump water either.

    Is there something specific about the anti-halation layer of APX that specifically reacts with Rodinal to effectively dissolve it in just the dev? Or are we just dealing with Rodinal's propensity for surprising colors after the dev cycle?

    Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.

    I've noticed this with any film that I've developed in Rodinal. The stronger the developer, the stronger the color.

    See, that's just the thing. I don't notice it with every film with Rodinal. In fact I just recently processed some SS and Acros and can't remember anything but a clear wash. Negs were fine and developed fully. 1+50.

    I think it is the film, rather than the developer. I notice the same red colour (not as distinct as yours) when developing APX100 in Rodinal. FP4+ in Rodinal turned (if I remember correctly) the develper brown/red, and Fomapan 100 in 120 format went blue! A bit odd, since Fomapan 100 in 135 format does not colour the developer. Guess there was some residue left from the tape or backing paper on the 120 roll.

    Really? I've developed and have seen others develop quite a lot of films in Rodinal, but nothing from Fuji. Everything turned used developer from magenta to purple. I can remember TriX, HP5+, Delta 100, APX100, TMX and there could be more.
