Or possibly it says that in my White Lightning docs, but I hardly ever look at those, so I'm pretty sure it's in the camera manual. This makes no sense to me, and I have not attempted to experiment with it and see if it's true, or in what ways it fails. I'm away from the manual just at the moment (those pesky day-jobs), I'll try to remember to check to night exactly what it says. -- 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
