    Gentle agitation

    In the rodinal semi stand disaster thread Gainer asked what is the definition of GENTLE agitation and what is its virtue. I have not got a clue ,but this is what I do: (1) I gently invert my paterson tank letting the developer flow smoothly through the reels just fast enough so that the dev does not froth or splash about. (2) I then swirl the tank anti-clockwice twice (3) The tank is returned upright and inverted again, this time I swirl it twice clockwise. (4) Once the tank is upright again I rap it twice on my worktop to remove air bubbles. I have always done this. Have I been missing something? Is there any good reason not to continue doing this?

    If you are consistent with your methods and happy with your results, then you got it made! I usually miss a cycle somewhere along the line, trying to find my bottle of beer.

    One should never have consumable beverages in the dark room anyway. Picking up the wrong vessel in the dark or semi-dark can be very dangerous.

    I figured that he loaded the film in a changing bag and was processing in the kitchen with the lights on. That way he could safely drink the beer and be close to the source.

    "I figured that he (...) was processing in the kitchen with the lights on. That way he could safely drink the beer and be close to the source."

    Is there any other way???

    Not sure of the real definition of "gentle agitation" either. I invert twice every 30 seconds, rap the tank on the table, give it a little turn...and have a sip of beer.

    Extra edge density on roll film can occur:

    For semi stand,where I obtained extra edge density with gentle inversion,I am going to try twirling with the spin stick.

    If I kept my selenium toner in a wine glass, I would worry.

    I tend to do the drinking BEFORE developing or deciding to develop. I'm always surprised when I don't screw up
