Have you ever seen a row of professional photographers kneeling down on a sideline? They sure are lazy. Or maybe they know what they are doing. What about somebody you've paid to photograph your kids - did he or she kneel down?
Lots of times we can improve our photographs by getting on the same level as our subject. This is particularly true when photographing kids. While I have seen lots of pros getting their knees dirty, I don't see moms do it very often. But if you kneel, squat or sit, I think you'll like the results.
Getting on your kids' level makes your photographs seem much more personal. It makes the viewer feel like part of the scene instead of like an outside observer. Check out the difference it makes in these pictures:
