    Just going through some old exposed films and processing them. Put the bleach and fix in the wrong jugs and swapped them - doh! Is it possible to go back and re-bleach them now? They are too thick to even scan unfortunately.

    Thanks!

    Bleach and then proceed in the common order.

    The concept behind the saying "measure twice, cut once" applies to things other than carpentry. Label all containers and check the label twice before doing anything. It's also a good idea to include the mix date and other information such as times used on the label.

    Not all mistakes are as easily corrected. Some mistakes can be dangerous or expensive.

    Yes. You've done what's called a bleach bypass. The film will scan, but will probably give you a gritty '300' (the movie) kind of look. Like AgX said, just bleach/fix/stabilize again.

    Great. I was hoping for the bleach bypass look - but for some reason it's not scanning.

    Bleach bypass often involves a shortened time in the bleach but not to completion.

    You have to turn off ICE (infrared light based dust&scratch removal) - the retained Silver won't let the infrared light through, messing up the algorithms.

    Preachy, but non-responsive.

    I am trained as a chemist and the darkroom can be as dangerous as any lab. Perhaps even more dangerous since those doing their own processing often have no training whatsoever. Showing someone how to be careful is far from being "preachy."

    Let me be preachy too:

    Line up the marked stock solution bottles in the sequence they will be used with the respective beakers in front of them. Or even better, just the beakers alone, but marked then, in that sequence.

    That's what I do. Line them up to the left of my 'processing center' (sink) and then move them to the right as they are used.

    Also, I have a habit of smelling each stage. Bleach smells like decaying apples, fixer smells like ammonia and rotten eggs (sort of) and developer usually doesn't smell like much at all (to me).

    BLIX is obvious since it's deep blood red and smells the worst.
