I take tons of pictures of my kids. Seriously. Sometimes when we go to the park I'll take 170 pictures. The Sarah school of photography says that if you take 100 pictures at least two of them will be really good. It isn't the most efficient process, but my digital camera allows me to do this cheaply.
This morning I found much better advice on taking great photos of your kids. JMadigan posted 5 tips on taking better pictures of your children. Jamie Madigan has beautiful pictures of his daughter and he has really effective suggestions like getting down and close to your subject, paying more attention to your background, and keeping an eye on where your child is placed within the frame of the picture.
Even better: don't be afraid to stage a shot. While we all love candid pictures of our kids, sometimes creating a planned picture can be really adorable. Go check out his site, I had never been to his site before this morning, but I'll be going back.
