Subject and action A male soldier with clear muscles and strong physique stood straight in the helicopter cabin with a calm expression. He is wearing a well-made tactical military uniform, and his face has extremely fine and realistic skin texture, with fine pores and natural skin tone texture visible. Composition and Lens The front is centered on the composition and a 16mm wide-angle lens is used to shoot. The edge of the lens presents slight perspective distortion, which enhances the sense of depth in the space and the sense of on-the-spot pressure. Light, shadow and atmosphere Light naturally shines in through the helicopter window, showing the contrast between the cool natural light and the shadows in the cabin, creating a calm and restrained military atmosphere. The air is filled with the coldness of metal and the faint smell of engine oil, and fuzzy clouds and high-altitude vision can be vaguely seen in the background. visual style The overall style is biased towards a realistic film sense. Referring to Christopher Doyle's lens language, it emphasizes high dynamic range and texture performance, and color restraint, presenting a delicate graininess like Kodak Vision3 500T film. constraints No text, Logo or watermark shall appear on the screen.
