    @Michael This sounds good. I will have to shoot, soup a roll and report back.

    An excellent point to remember.

    I bought a white two gallon plastic paint pail ($4 at Home Depot) that I fill with water for a water bath. After processing, I use the water to wash the film, then when empty, I use it to store all the graduates, etc.

    Well everyone. After testing -- simply inverting the tank (metal reel tank) and alternating the axis of rotation every 90 degrees every other flip worked MUCH better than torodial agitation. The negs looked indistinguishable from beginning to end.

    Thanks for the Help,

    used this method - 20 years+, may be wrong but works for me too!!!

    someone else said, "don't overthink" - good advice.

    Everybody knows my method is the best! Anybody who does it differently and gets good results is just plain lucky. Sure, a figure eight might work good for you, but that's only because you are probably swirling it fast enough to generate random Von Karman vortices. Not everyone has your forearm strength, you know, and studies have shown that Von Karman vortices, while setting up sufficient agitation, can in fact introduce micro-reticulation in certain maniform sections of carbon based films, particularly if one does not consider the weak anthropic principle. Fool! I can't believe I even hang around here!


    Oh wait, were talking about agitation, not agitating. Sorry John. I've been monitoring some threads that are pretty much like that.



    ...Seriously, I think there are probably as many ways to agitate as there are agitated analog photographers. The one that you find works for you, is the right one. Probably because everybody is different. A unique snowflake.

    Jeez, now Jason is calling me a snowflake. (I'm sure it was a personal attack even though I haven't posted in the thread. I can just tell these things.)

    Damn, where are the moderators when you need them.

    Oh wait, he is one.

    Well, my purpose for posting the original question was met. How do I agitate a spiral tank to get even development. I now know.
