I think we're dealing with the inherent resolution of the pinhole itself. Still, reducing the exposure time could be beneficial for lots of reasons. Or undesirable for others; some people use pinholes as a way to make very long exposures possible. -- David Dyer-Bennet, dd-b@xxxxxxxx; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info
