A cinematic slow-motion underwater shot of a happy dog diving toward the camera with playful energy. The camera captures from below as sunlight refracts through the rippling surface, illuminating the dog's fur and bubbles swirling around. Water particles and reflections move dynamically, the dog paddles joyfully with its paws, mouth open in excitement, and air bubbles trail behind it. The shot transitions between slow and fast motion for a dynamic cinematic feel. Ultra-realistic underwater lighting, wide-angle lens, crisp water clarity, joyful mood, 4K cinematic realism
