Hi - I am currently using 5x4 film (Foma 100 and HP5+) and developing in an HP Combi? sheet film tank using Diaphine.
I wish to use the 5x4 negatives for Alternate Process contact printing with Cyanotypes, Vandyke Browns, and later on Gum Bichromates.
Most of the negatives I have processed so far are very flat and seem to have more than the fog level I am used to. I chose Diaphine because the above tank takes me at least 45 seconds to fill / empty and the Diaphine seems to be fairly time tolerant.
And so can anyone recommend a developer that I could try that has a fairly long development time (say 10 Minutes), so I don't get uneven development, and will also give me a decent contrast for the above processes?. It would be really nice if I could develop both types of film I use at the same time but this is not essential. But I would like to be able to just have the one solution for both films. I would prefer to mix a large amount of stock solution and dilute for 1 shot use if possible.
Sorry to be a bit particular
Thank you all in advance for any replies
