Is there information on how to test for recriprocity failure of my film and developer combination? I have just upgraded to the new Plotter and Expodev, so I now have the ability to set these variables, but I don't have any information on how to test for these.
I am using a fairly uncommon developer that is a bit of a 'homebrew' developed by Sandy King, Pyrocat HD, so it is unlikely that there will ever be recommendations for this developer.
The BTZS book has some information on reciprocity testing, but I don't see how that applies to the correction factors built into the Plotter/Expodev.
Thanks,
---Michael
