Wow, what a great read. Thanks Steve, Ian, and those who have contributed!
As a side note, I've been using Acros 100 and Neopan 400 for about 7-8 years exclusively with Pyrocat, but whence I switched to 4x5 recently I decided to give FP4 and HP5 a try. The tonality of my prints jump off the page...what a difference! This is with semi-stand development of the two, at box speed, for 13 min.
Might have to give this method a try. Thanks again!
