A photo of a fantastical underwater city, captured with a Nikon D850 camera, f/5.6 aperture, 16mm focal length. Towering, futuristic structures made of gleaming metal and glass rise up from the ocean floor, surrounded by schools of brightly colored fish. Intricate, bioluminescent lighting systems illuminate the city, casting an otherworldly glow. Kelp forests and coral reefs stretch out in the distance, creating a lush, alien environment. The water is a deep, azure blue, with shafts of sunlight filtering down from the surface above.
