햇살 속의 고래상어

Create a realistic wide-angle underwater wildlife photograph of a {argument name="main animal" default="whale shark"} swimming diagonally through deep blue ocean water, viewed from slightly above and in front so its broad spotted head dominates the lower-left foreground and its tapering body and tail recede toward the lower-right. The whale shark should have accurate white polka-dot and stripe markings across gray-blue skin, visible gill slits, pectoral fins, dorsal fins, and a graceful slow-swimming posture. A single scuba diver silhouette with fins and tank appears far above the shark near the upper center, small for scale. A warm golden sunbeam cuts diagonally from the upper-right toward the lower-left, illuminating suspended particles, bubbles, and plankton in the water. Use natural light, deep turquoise-to-navy color grading, soft underwater haze, realistic caustic glow, cinematic depth, subtle motion blur in drifting particles, and an immersive documentary feel. No text, no borders, no artificial aquarium setting.
