A dramatic, low-key lit, cinematic photo of the deep blue sea

A dramatic, low-key lit, cinematic photo of the deep blue sea, capturing the vibrant colors of a thriving underwater ecosystem, with a vast array of coral species, including brain coral, fan coral, and staghorn coral, swaying gently in the ocean current, surrounded by a kaleidoscope of fish, including angelfish, butterflyfish, and parrotfish, their iridescent scales shimmering in the faint sunlight that filters down from above, the overall mood evoking a sense of tranquility and wonder, with the camera positioned close to the seafloor, looking upwards, creating a sense of depth and immersion, the image framed by the undulating curves of the coral reef, with the blue water gradient fading into darkness at the top, and a subtle mist effect adding to the sense of atmosphere.
