cute idea for a Christmas card
Christmas Baby Photo ... the trick is not to do it in full darkness. Get the room dark enough to see the lights well and set up a "bounce card"...we used a white "presentation" board...one of those fold out white cardboard paper things that's about 4x6? Put that next to the baby but out of frame and it will bounce light back onto the baby.
How to take awesome pictures of lighted things (like a christmas tree). "We gave this tip last year, but it’s worth repeating! Turn off your flash, along with all the other lights in your house, crank up your ISO, use your tripod, and meter on the light from the tree."
