It turns out our biggest problem has been the fact that we tend to use a flash (because, dur, it's night-time). According to photographer Linda Russell, who compiled this list of tips for the Orlando Sentinel, you should "Turn off your flash and use a tripod or even the back of a chair to stabilize your camera and use a slow shutter speed to photograph your child by jack-o-lantern or candle light." (She doesn't mention how to get your adrenaline-and-sugar-fuelled subject to sit still while the shutter closes, so you're on your own there.)
Other tips include going for the classic flashlight-under-the-chin shot and remembering to take a photo of the Halloween candy haul. Read the full article here.
