PROMPT:
Create a breathtakingly realistic underwater scene on a bright sunny day, teeming with vibrant turquoise, electric blue, sunshine yellow, and emerald green hues. Capture the intricate details of a vast, ancient coral reef, awash with schools of rainbow-colored fish darting through the waving sea fans and giant kelp. A majestic sea turtle swims serenely in the foreground, its shell glistening with dew-kissed droplets. The sunlight filters down from above, casting an ethereal glow on the undulating waves, while the ocean floor is littered with glittering treasures and mysterious artifacts. Incorporate air bubbles, seaweed, and other organic elements to enhance the photorealistic texture and sense of depth.
