Raghu, thanks for your latest post and information. Alas! I've not yet made it out to the great outdoors due to a combination of events, a bitterly cold spell here in Tasmania, 'flu, and some unexpected business to be dealt with (and sadly, paid for). At my age, I enjoy the delights of long, leisurely (okay, slow) rambles in the countryside (we call it "bush" here, however rural it is) with a not-too-heavy camera (Rollei) in hand and some not too difficult film to work with. Which XP2 certainly looks to be.
I will definitely get out and about this coming weekend and I plan to shoot at least two test 120 rolls then. Going by the good advice of Mick Fagan and others, I will initially shoot a series of same shots at ISO 400, 200, 100 and 50, and then continue my trek into the wilderness at ISO 200 which from what I've read, appears to be the sweet spot for this film/developer combo.
I have the scales and raw chemicals at home to mix up a potful of Adox MQ Borax developer and in fact I've long wanted to test out this developer which many here, notably Ian Grant whose good advice I have long been following, have recommended. So be it. XP2 at 200 and Adox MQ Borax it will be. A new enlightenment dawns.
I have just now spotted another thread by you, Raghu, on archival stability of XP2 processed in B&W chems and I will be reading it as soon as I finish this one and send it off into the universe. So I may yet have more to comment, tho' I'm inclined to wait until I've shot and processed my test rolls before opening my mouth yet again.
So "a bientot", as my French Canadian ancestors would have said. And again, many thanks.
