If it is a child or a group of children, there are certain elements that need to be considered.
If you take pictures small children, you'll want to pre-focus on first. In most modern digital cameras, it is done by pressing the shutter button halfway. Then you have to move yourself forward and back with the child to keep a snapshot of attention. Another great tip is to take a child easier to get to the level that you seem less intimidating. To get an even better and more interesting shot, especially if you have a group shot of children to distract them just before shooting their attention away from the camera, it will cause a lot of nature photography.
Using some of the tips above should allow you to capture more interesting pictures of your child or children in a way that would be more interesting to the group, and then capture the fun of childhood.
