A deep-sea coral reef scene, a tropical underwater world dominated by blue, with a large area of healthy and prosperous colorful live corals, including branch corals, brain corals, disc corals and soft sea fan corals, with a large number of tropical fish naturally shuttled among them. The close-up view is clear and vivid, while the distant view gradually turns bluer and grayer, and the contrast weakens. The natural light above is filtered by the seawater to form a soft volumetric light. There are small suspended particles and a slight sense of flow in the seawater. 8-12 of various sizes. The umbrella-shaped body has a soft bioluminescence effect, the tentacles flutter gently with the waves, and there are faint purple light spots at the ends of the tentacles. The size of the jellyfish is in proportion to the corals and fish, and the luminous effect is soft and non-glaring, forming dreamy spots of light on the dark seawater background. The movement of the jellyfish swarm is natural, in a slowly rising spiral, and some jellyfish swim past the front of the lens, creating a slight lens flare effect. Keeping the blue-toned lighting underwater, the glow of the jellyfish coexists harmoniously with the faint reflections of the surrounding corals. During the swimming process of the jellyfish group, bubbles were generated, and the bubbles floated up, forming the word "Seedance" in the sea.
