    Heavy purple cast on pushed T-max 3200

    So i have put hundreds of films through rodinal 1+100 stand for an hour and they have all come out fine, i have never pushed with rodinal but since it was the only developer i had i thought "why not" so i googled and put it in 1+25 for 10.5 minutes with standard 5 seconds every 30 seconds agitation. I rinsed, washed and fixed using Champion rapid fix for the same amount of time i usually fix for (ashamed to say ive never measured the time)

    i pulled it out only to find a pretty heavy purple cast over the film, the negs have pretty good detail and should print ok im just wondering what caused such an intense cast ?

    Rodinal is usually really good for lifting out dyes and ive never had a noticable cast on previous 1+100 negs

    any input would be appreciated

    many thanks
    Samuel

    oh, i have attached a really rubbish picture of the negs i took with my phone just to give you an idea of the colour

    Looks like one of the dyes was not removed properly.

    What fixer did you use, and did you use a wash aid?

    I would guess a rinse in Sodium Sulfite would remove the dye.

    Nothing to do with being pushed, everything to do with your fixer.

    When you say "same amount of time you've always fixed for" do you mean always fixed for TMZ? I ask because T-grain films need fixing for twice as long as non t-grain films and you can't use the same times as other films.

    For me, anti-halation dye that won't clear is usually the first sign of fixer getting weak. It's recommended that one fixes this film for a minimum of 5 minutes, more normally 7 minutes, and preferred 2 separate fixes of 5 minutes each. HCA will also help to remove this dye, as will a long water-soak (both too late now).
    Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.

    Clayne;

    Forgot the fixer connection. Thanks. I'm getting old!

    As for being too late, maybe not with the Sulfite. It can destroy dye. There are some other treatments that might work too, but re-fixing and washing followed by a wassh aid and a rinse might do the trick.
