Hello everyone! I just got a new camera, the canon 30d and am having trouble figuring out how to take a picture outdoors without my flash going off, so I can use the natural light, and also at night to take silhouettes...I've practiced with different manual modes and the darn thing goes off everytime...this hasn't happened to me often....any suggestions would be greatly appreciated!!!

If I was the OP I'd already be on the phone to Canon.
