Keep it Simple
Aim for a soft-looking background, such as a puffy, light colored comforter. Create a continuous background behind the baby, avoiding lines formed by the edge of a blanket or change from couch to wall. Babies are happiest when held; a draped parent can serve as the background.
Zoom In
A single-focus camera simply cannot capture a baby's details like a close-up shot. One of your best new baby investments will be a camera with a zoom lens. An auto-focus, auto-flash, zoom camera can yield wonderful results.
Lighten Up
Fill the room with light. Open blinds, drapes, and curtains. Use room lights to shine into any dark areas. If you use a flash, step back and zoom in before taking the shot.
Be Willing to Wait
The appearance of newborn babies improves significantly after the first few days. You will get the best shots after the first week, when the temporary imperfections from the birth have disappeared.
Warm and dry
While your baby is sleeping, set up your photo area. After your baby is awake, warm, fed, and dry, position her and start photographing. Be sure to reduce stimulations like noise from the radio and television. Repeat this process over several days to get different expressions.
Position, Position, Position
If you've seen a pose you like, copy it. Try to keep the arms close to the body and hands near the face if possible. Use mom or dad's hand under a blanket to hold him up from the back. Get down on the floor and shoot at eye level.
Photographing twins or triplets? The closer together the babies are, the better. Avoid spaces between the babies. Nestle them with their heads touching. For triplets, consider placing the babies head to head with their bodies extending out from the center like spokes of a wheel.
If you want to photograph an older sibling with your baby, avoid the "big sister holding baby brother" shot. The older child dominates the photo and steals attention away from the newborn. Instead, place the child and baby's heads close together to create a balanced focus. Take a few photos with the sibling looking at the baby instead of the camera.
