One of the best ways to improve your photographs is to get down to the level of your subject, especially if those subjects are children. The bird's eye view of the baby in the crib, or on the floor is okay, but not always the best or most engaging. Aim for eye level, and as I mentioned before... fill the frame!
When I am out shooting weddings, people are often surprised at the various positions I will get into to take a photograph. Don't be afraid to lie on the ground or stand up on something to discover a new angle. How about vertical shots? Did you know that you can rotate that baby (the camera) and take a pic with the narrow end up? Vertical shots are especially good for single subjects.
Also, try this one... take a photograph on an angle. It can add motion and an artsy feel to what you have captured.
Always be generous in your picture-taking. This is the digital world! Take LOTS of photos in LOTS of different ways and don't delete a one of them until you have downloaded and worked with it. Buy a large memory card and carry a spare. You won't regret it.
As usual, have fun! And don't forget to post some pics! I don't mind if you enter more than one photo for the contest! That $25 gift certificate and interview has your name written all over it! So post some now, and post some later. :-)
