Exposures can go from 2 seconds to XXX minutes on a pinhole camera. Don't sweat over "long" exposures. Who cares about reciprocity. A pinhole photograph will not be perfect, but it will be a very nice artistic variation on the bog standard photography of SLRs, digital, and anything else you can think of. Be it noted that the nature of pinhole cameras is to record the image in time often a lot of it. DaVinci took 5 weeks to record the Sun's movement in the Tower of Winds using the first known pinhole!
