Split-View Tropical Sea and Sunny Shoreline with Underwater Scenery

Ultra-clear tropical sea on a bright sunny day, cinematic split-view camera angle — top half above water showing blue sky with a few fluffy clouds, distant palm trees and a peaceful shoreline, bottom half underwater revealing white sandy seabed with gentle ripples and light refractions dancing on the ocean floor. Crystal-clear turquoise water, small bubbles and sun rays penetrating through the surface. No people. Serene, photorealistic, high-detail, nature documentary aesthetic. Shot on ARRI Alexa 35, vibrant lighting, soft shadows, slow summer mood.
