Rodinal and Tmax, or Help me get my process under control!

I am curious - if you have always had great results in your Jobo, why change? IMHO Jobo's agitation is about as controlled as you are going to get.

Jobo's agitation is full agitation. It's agitation is extremely consistent, but it can't be "turned off". My goal is to be able to use, for example, highly dilute rodinal, and do, for example, stand development. That's not possible with the Jobo.

When I say I've had great results, I have - but within the constraints of the Jobo. I love the consistency with E6, for example. But I am beginning to understand the lack of control (perhaps I should say lack of optimization techniques) I have with B&W development in the Jobo.

I think I understand. Are you proposing this technique for normal development or is this to help you with high contrast situations?

If you want a complete control of your inversion development, specially with developers like: Rodinal, Tanol, AM50, CG512 and there are some more, I can only recommend the Heiland TAS processor. Tanks from Jobo 1500/2500, Kindermann, Paterson can be used in that automated inversion system.

Also the longer developing times are not boring anymore. The system is also compensating in time the temperature deviation.

Further Rodinal is more or less a better choice for classical lower speed films. Same like AM50.
But the choice of a film/developer combination is more or less a personal preference.

Best regards,

Robert
