I'm spending 3 weeks in Europe in September, travelling from Colorado where I live. Roughly 1 week each in Amsterdam, Barcelona, and near Siena. I'll be taking a ton of digital vacation photos as the assigned chronicler of our trip, but I'll also be dragging around a 6 x 6 pinhole camera (my converted Voigtlander Brillant). I just wonder what other folks experience is with pinholing on vacation, and any things to worry about while doing the slow photo method while someplace far away from home. Issues people have run in to, and things that work. Also, any suggestions to must see for photographer places would be appreciated...
