This is the easiest way to bring a smile to your child's face...let them use your camera. Yes, it's a little scary. Make sure you are in a safe area, lots of grass - minimal pavement (in case of dropping). I passed the camera to my 5 year old the other day and asked her to go and take 10 pictures. Her pride was blooming, and she took some pretty good pictures.
Funnily enough, when I looked at the pictures I wasn't even sure where she had taken some of them! A whole different perspective on our very familiar park.
