Hello I have an Olympus C2040 digital camera and I have been attempting to shoot night picture without a flash, in order to capture the appropriate mood. Mainly taking pictures of Xmas lights for the holiday season. I notice when I do this though I get slight blurring to the lights themselves. Could it be because I am not shooting with a tripod and the camera is moving ever so slightly when I shoot? I am shooting with a with an open apature so the picture isn't so too dark. Any suggestions? Thanks, Michael
