I bought a pack of 4x5 Arista.edu ISO 200. I couldnt find the development times ANYWHERE!! : (
digitaltruth's chart says to use the same time as agfa apx films.. is this true? Should I dare try to develop with anything but sprint? (I have rodinal that I might want to try with 4x5)
Currently it is Fortepan 200. Nice film. I would try it in Rodinal 1+100 for 30 minutes at 20C with 2 inversions every 2-3 minutes (for silver printing). My favorite soup for it is Pyrocat HD.
I agree with the variation comment. I've not used the Arista.edu 200, but have used about 20 rolls of both the 100 and the 400.
I love the 400, it's great. The 400 was about as fast as the 100 and just all over the map as far as defects and contrast went
Just my experience, may certainly not be yours.
