My main films are all Kodak - easy to get where I live (and cheaper...)
PX @200 and TX @500 in ascorbate dev (Yes, I've done Zone 1 tests; this is OK for my lighmeters/cameras combo).
TX @1250 in Diafine clone for available darkness shots.
In the past, I've used mostly FP-4.
Curitiba - nice place to live, if you don't care about the weather...
I don't ever remember being particularly enamored with Panatomic X back when it was available. Finer grain than Plus X was about all that recomended it. I always used Ilford Pan F as my slow, fine B&W film. I don't know whether it is the reformulations over the years but I am even more impressed with it's grain and tone now. I rate it at 50 which is fine for general use in most outdoor situations, even hand held.
That is called grain. It is supposed to be there.
Been using FP4+ and HP5 myself which I really enjoy. PanF also when I was shooting more 35mm. The reason I asked is that I've never tried Tri-X (I know!!!) and several people have recommended getting a box so was interested to see who really favours it.
mobtown you'll notice I've changed my avatar - didn't want to tread on your turf and get caught out down town! (thinking about trying your film though).
