Thanks for all your help guys, I can't wait for my cam to come to try this all out.

Does anyone know how long an exposure the 1Ds MkIII can do at ISO 1600 before some of the dark pixels start to turn bright, as in making the final picture look like it has tiny, single pixel specks that are red or white in it even if it is a shot in the dark with lens cap on? These pixels are fully bright but disappear in shorter exposures.

I use magic lantern to do intravalometer exposures, its free. Definitely give it a try!

Ditto on Magic Lantern, it's free and available to a large portion of Canon cameras
