I'm a big believer in crisp, tight framing. My usual advice is to get in close, eliminate the clutter, and focus on your subject, leaving no doubt what your photo is about.
Christmas morning demands a different approach, though. When the children are unwrapping presents, go wide. Include the clutter, because it's part of the story. Take the picture from floor level, so you retain the wrapping paper, empty boxes, and other debris crowded around the kids, for example. Or climb up a flight of stairs and shoot an aerial view of the holiday in progress. Photos like these capture the spirit of the day. Chaos and clutter: It's endearing.
