Using my light meter set at 6 ASA/ISO, the exposure time can be read at f/45. On a bright but cloudy day this is about 4 seconds. This is too short for my liking (people are still visible), so I'm going to cover the pinhole with a Neutral Density filter, better still a (circular) polarising filter.
