On a 6MP camera there are 6 million photosites. Either that or there are no 35mm-derived 6MP cameras, but in that case you're arguing for a variant set of definitions which, while sensible in its way, is incompatible with the wya everybody in the field uses the language. -- David Dyer-Bennet, <mailto:dd-b@xxxxxxxx>, <http://www.dd-b.net/dd-b/> RKBA: <http://www.dd-b.net/carry/> Pics: <http://dd-b.lighthunters.net/> <http://www.dd-b.net/dd-b/SnapshotAlbum/> Dragaera/Steven Brust: <http://dragaera.info/>
