Re: Pyro and rotary agitation question



I was just talking to a friend about processing roll films in pyro about 10 
minutes ago! She was taught to fill the tank with developer, and with the 
film rolled loosely, lift the middle end (does that make sense) of the film 
strip out of the solution and keep dunking it for the duration of the dev 
time. -Lifting all of the film in and out of course, but keeping it in a 
spiral shape. This is all obviously done in complete darkness.
Don't know how effective it is yet. I'm about to start doing tests with pyro 
in a week or two...
