I was in Warsaw about 7 months ago for a conference, and found time to do the Stodola show and to visit Czarno Biale. I didn't find anything of particular interest at the show, though I was tempted by a few Russian lenses. But who doesn't like going to a camera show, if only to see what's going on locally and meet some people? I don't speak Polish, and the lady in C-B didn't have strong English, but we managed to communicate just fine, and I walked away with some developers, including a pouch of D-74 by Calbe -- haven't tried it yet.
I also managed to catch a concert at the national concert hall, and drink some terribly rich chocolate. All in all, I enjoyed the visit!
