My niece has been doing some photography on Aunty Allie Tuesdays. I have an extremely childproof point-and-shoot camera (waterproof and therefore ideal for three-year-old usage), and I've found that photography is a great way to get the kids outside and running around, looking for things to photograph.
I think children's photography is incredibly interesting - a glimpse of their point of view of the world, which was ours once upon a time and which we've forgotten. How they see the world and what they think is important. So here are some 3-year-old-Niece's shots, for your viewing pleasure.
