I have just obtained a Jobo expert tank to develop 5 x 4 film with a CPA2 processor. On reading the instructions(!) Jobo recommend a pre-wash I am using Silverprint Pyro I have never used a pre-wash with this developer or any other developers i Have used in the 40 odd years of processing film.
So before I test whether to use a pre-wash can you advise me if I should use one or not.
I notice in this recent thread http://www.largeformatphotography.in...en-development that someone recommends 2 pre-washes.
I will also occasionally be using E6 and C41 processes should I pre-wash these?
I would pre-wash using distilled water
Thanks in advance for any of your observations.
