It's pretty much permanent, some other camera makers provide a hot pixel mapping service Pentax seems not to. They happen because not all of the pixels have the same characteristics, some are inherently more noisy or just plain broken. The ones that are more noisy saturate due to self noise much earlier than the ones surrounding them, some are just stuck on permanently and occasionally some just don't work at all, they are dead pixels. > I don't have this problem with the DS2 as yet, and I don't want to. How do I > avoid it? It may develop over time, I know my *ist D was delivered with hot pixels and is a bit worse than when I bought it. It's a bit of a pain when I'm shooting using slow shutter speeds on a light table but other than that they aren't a great problem. You may find the program FlameOut useful though it's only available for Windows. http://www.nightwatchsoftware.com/flam/flam.htm Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://members.ozemail.com.au/~distudio/publications/ Pentax user since 1986, PDMLer since 1998
