Man studying giant fish under headlamp by dark water

A man wearing a blue button-down shirt, white gloves, and a headlamp with a light beam illuminating the scene, carefully examines a massive Goliath Grouper. The fish is partially submerged in shallow, dark water, its scales glistening under the artificial light. The background is predominantly dark, with faint, distant lights suggesting a shoreline or town at night. The overall mood is one of awe and focused observation, captured in a realistic, documentary-style aesthetic with dramatic, low-key lighting. The shot is framed from a low angle, emphasizing the immense size of the fish. Shallow depth of field blurs the distant background, drawing attention to the man and the fish. High detail, realistic rendering, naturalistic color palette, cinematic feel.
