    Fixing: Too Much Agitation?

    Is it possible to over agitate your film during mixing? I dont think so but want to make sure that I'm not missing something key.

    I like to error on the higher side of agitation for fixing if there is no down side.

    Thanks!

    I think it's possible. I have never tried this but I believe that if you agitate in violent bursts of very short and quick jerks and do it during the whole fixing period that you will over agitate.

    On a serious note, I don't pay much attention to agitation during fixing. I do a bit in the beginning (say 20ish seconds, not more) and then here and there when the mood strikes me, and sometimes it doesn't strike me at all. Never seen any difference. I am pretty sure you are safe, so long as you are a sane person.

    I agitate continuously for 5 minutes in 2 baths, admittedly overkill. Never had a problem. You'd probably have to agitate for an hour+ to see an issue.
    Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.

    Doesn't Kodak recommend constant agitation?

    Doesn't Ilford recommend the same agitation scheme as when developing?

    I prefer to irritate my film when it's in the fixer bath. I kinda stare at it and keep poking it and asking, "Are we done yet? Huh? Are we done yet?"

    When I was in college, I would constantly call the film in the drum my art professors name. One day she walked in and heard me doing this and asked what I was doing, "agitating the film" I replied.

    I don't know, let's look it up:

    Ilford: "then agitate, as during development, until fixation is complete,"

    http://www.ilfordphoto.com/Webfiles/200629163442455.pdf (page 9)

    Kodak: "Agitate continuously for the first 30 seconds and at 30-second intervals after that with a hardening fixer"

    http://www.kodak.com/global/en/profe...dbwf/edbwf.pdf (page 5)


    Agitation similar to developing: Yes. Constant agitation: No.

    I agitate in fix constantly for the first minute then just leave it alone for the remainder of the fixing time, normally a total of 3 minutes in rapid fixer diluted 1/5, so agitate for the first minute then leave it alone has worked fine for me for ever, following the suggestion from Johnsons of Hendon when I was a child, a firm now long gone
