Just like Newton had his laws of motion, photography has its rules as well. There are the Rule of Thirds, the Rule of Space, and others. Among these steadfast rules is the celebrated Duck Rule of Photography: "If you see a duck, you must shoot it."* No one who sees a duck while carrying a camera can avoid obeying this simple but powerful rule.
*Applies to geese, swans, llamas, and carousel horses as well
We saw this mother duck and her brood while walking the dogs.
