If you want more contrast, you're in luck. Pushing EI400 to higher EIs does just that. I can't advise you on what the best film/dev combination is currently, but lots of people swear by Tri-X in D76 or Xtol (e.g. Anchell + Troop in "The Film Development Cookbook")(posted 8311 days ago)If you send your film out, some development in excess of the standard time for the EI400 film would, of course, be necessary.
