Alex and her mom, two scruffy dogs, are packing for their New York City trip when they realize mom’s camera is lost. While searching for the camera, Alex asks her mom "How does a camera work?" Alex learns through everyday objects like a mirror, magnifying glass, and even the pupil of her eye. Mom shows Alex her NYC photos while explaining key photography concepts like aperture, shutter speed, zoom, composition, portrait and landscape orientations, and long exposure photography.
