Here's the deal: In about a month and a half I will be taking a trip to northeastern Brazil, like I did in 2002, and plan on shooting LOTS of film. Last time I was there I found two labs that processed B/W, one was a small business which used hc-110, the other was a bigger lab which used XTOL. Being familiar with hc-110, I used the small lab at the time, which was also very cheap. I quickly learned why. Most my negs were over way developed, and I later learned that they had NO temp control. Very scary. So this time I'm leaning towards the bigger lab, if they are still in business (cant see why not, though). The problem is I have absolutely no experience with XTOL. For the past year or so all I've used was d-76 1:1 How do tri-x and the Macophot (efke 100?) compare in these two? I ask because I tested the tri-x and began to test the Macophot Up-100, and have found the true E.I for both (or at least got close on the Maco). It is irrelevant what the E.I. was, since it relates mostly to my meter and how I use it (well, tri-x at 200, Maco at 80), but I want to know how to rate these films when I'm there. I know, the correct thing to do would be test them, but I can't process film at home as of yet, and being a college student who works his butt off as well, I simply don't have the time. so, if anyone has experience with either film in XTOL and D-76, or even just XTOL, I would appreciate it if you share. I just don't want to lose any pictures... Worst case scenario, I'll just keep rating both at 200 and 80.
