As a general rule of thumb, my answer is "15 megapixels". This is because very very few people ever make prints large enough for 15 megapixels to be less than adequate, but people often do shoot at high enough ISOs for any gain there to be of value. But that's just a rule of thumb. Also, the difference between 15 and 18 is small enough, for both issues, that the other answer is "Doesn't much matter." -- 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
