    does that not dirty your fixer badly? I'm sure there would be some variation caused leaving developer on film with the fixer no?

    I do a wash between the baths, just no stop. Even that wash isn't really neccessary anyway, I use my fixer one-shot for the most part so not really concerned about contamination.

    ah well thats what i kinda meant by stop, i chuck it into a water bath for 5-10 mins between fix and dev, dont add chemicals or nothing to strip the paper coating

    to strip the what ??!? If you're talking 120 here, You know you're only meant to put the FILM on the reel, right ?!:D

    Honestly I don't really know what he's talking about here with his "chemical negative destruction". Skipping the stop bath won't do a thing, and as I said above, you'd have to fix for a long long time to see any appreciable effect from it. I don't think that that shot would have looked in any way different if it had been developed normally.

    hummm, so these apparent technique is just extended fixing with no washing between dev and fix?

    that's all he's mentioned all right. There is a shot there that looks as though he's melted the negative or something. That certainly ain't gonna happen just by fixing it too much ...

    I do recall that during the same time I soaked a test strip of developed negatives in Ilford Hypam at the 1:4 dilution for over a week, then washed and dried normally. A year later there was no observable difference between that test strip and the baseline strip from the same roll of film that was fixed for the normal few minutes.

    a week :D
