These pictures are the result of a kind of "madmen's" project: shooting pinhole at night-time. After some good tips of Eddie Gunks and others, I finally settled on TMax 400 with these results. This film has a relatively low reciprocity failure, limiting exposure times to acceptable levels.
My MP3 player with downloaded Italian radio RAI podcasts (I'm learning Italian) is a very patient friend. Besides that, an occasional curious passer by causes some distraction... and just watch the look on peoples faces if you have a wooden pinhole installed on your tripod ;-)...
