Hi all,
I have been developing 4x5 sheets of FP4 souped in highly diluted Pyrocat HD with Extreme Minimal Agitation technique. I built the Steve Sherman's developing tubes with 500ml capacity.
Now, I want to make a tube to develop same FP4 but 8x10 sheet in proper size so that I could apply my personal process time and dilutions of 4x5 directly to 8x10. I assume that how much chemical for how much square inches of film is important with this technique.
If I do a simple math; [4x5 (20 sq inches) with 500ml] equals [8x10 (80 sq inches) with 2000ml]
So I can build 2000ml sized tube for 8x10 then I could develop in same manner as 4x5 sheets, without the whole new developing tests for 8x10.
Does it sounds correct to you folks?
