Cinematic Alien Ocean Astronaut IMAX Vertical Shot

Cinematic photorealistic medium wide shot of a single male astronaut walking forward through knee-deep shallow ocean water on an alien planet, centered in frame, wearing a detailed white futuristic space suit inspired by Interstellar, with a fully transparent visor clearly revealing his focused and serious expression. Subtle water splashes form naturally around his legs as he moves with determination.

Behind him in the mid-ground stands K-47 Sentinel Unit, a tall monolithic rectangular robot with articulated segmented panels and a dark matte metallic gray surface, partially reflected in the water. In the distant background, a sleek futuristic spacecraft rests on the endless shallow ocean surface under a heavy overcast sky. Vast flat horizon, muted cloudy atmosphere, cool desaturated blue and gray tones, soft diffused daylight, natural skin tones, realistic water ripples, atmospheric perspective, subtle film grain, high dynamic range, cinematic depth of field, ultra high definition textures. Shot with ARRI Alexa Mini LF, 40mm anamorphic lens, ISO 200, aperture f/5.6, vertical 9:16 aspect ratio.
