We had so much fun "painting" with light! The room was buzzing with creativity. If you want to light paint at home, find a dark room, put a digital camera into manual mode, change the shutter speed to 15 seconds or long exposure setting, and use bright flashlights with focused light to "paint" in the air. It's that easy! Try out light painting at home and make sure to share your photos with the librarians!
