    Agitation without inversion

    Since the beginning I have used the inversion technique for agitation but recently I have noticed that my Krokus tank is starting to leak like crazy and was wondering how effective turning the stick in the center of the tank is for agitation?

    I am really clueless on this technique.

    When I used plastic tanks, I always used the washing-machine-twiddle-stick method of agitation. It always worked fine; I always had leaks when I tried to invert my plastic tank.
    f/22 and be there.

    As the last poster says the twidle stick works just as well, in a small tank - one or two spirals..

    It also can do wonders in exteding the life of the developer. I use this when I want to run say 6 rolls of C-41 in my 4 reel tank. I mix c-41 1L at a time, and I usually consider it good for up to 12 rolls if they are all processed soon after the ingredients are mixed, but it does not keep well past two weeks, particularly if a few rolls were processed in it when it was first mixed.

    It does oxidize quickly to aerial exposure. So just spinning means that I can run three reels, re-bottle the develper, and then run the second batch of three reels.

    I have tried using it with inversion agitaion in a apaterson tank, and it is oxidised off after the first round of films.
    my real name, imagine that.

    My own experience is that it can work, but I have trouble sometimes getting an agitation pattern that's right -- it's easy to get underdevelopment or streaks on negatives if you agitate too little, too much, or otherwise wrong. I recommend you set aside a few test rolls to see how it works for you. Include a range of films that require different development times.

    I always have dark edges on my negatives with the twiddle stick in AP and Paterson tanks. I tried slow, fast, right, left both ways. I never use it to agitate except initial agitation, stop and fix steps..

    If you want anti-anal results..this should work.

    Hello, I would suggest trying this technique. I can't give you any exact zone system answer that will give you high-light and shadow retention...but, will work fine.

    Keep you tank on the counter and move it in a continuos figure eight pattern. It also would be OK to use a figure nine, three, or four. If you use a figure one or two pattern,be sure to turn your tank clock-wise a quarter turn each time you move back and forth. Do this motion for the entire time. If you think it is to much agitation...pause- breath- relax and continue when you feel it is appropriate. and Yes, you can read a little humor in this post.....the idea is to slosh around the developer. Ofcourse, none of us real photographers would ever think of doing this approach..much toooo unpredictable. ;~))

    Have fun, good luck!...let us all know how it all turns out.

    I've always used the twiddle stick, and never had any problems developing up to 5 rolls in a tank.

    Ditto. If there is a center post on a plastic tank, use it rather than invert the tank. That is what it is there for.

    Same here when I use plastic. Never thought of inversion with those tanks......
