I've been using the Digital Rebel for a couple of weeks and I can't find a way to just cut the flash off. I shoot a lot of wildlife in low light and when that thing pops up it often spooks the subject. I'd rather have an underexposure than have that flash jump up. Plus, if you go ahead and shoot something like a deer with the flash you wind up with a glowing "demon eyed" deer and red eye doesn't help for that. Is there a way to just cut the flash off?
