I really love this combination and it has finally given me the look I wanted :-)
That is the main thing. I had been playing about with Rodinal at 1:100 with minimal agitation and gave FP4 something like 20 minutes with 5 secs agitation every 3 minutes ! Mostly floral pics and got nice negs although I have not printed any yet. Oh, I forgot to say that the developer was a few years old and the film well out of date !
