An enormous abandoned military submarine half-sunken in a foggy temperate forest swamp, hull scarred, rusted and dented, covered in moss, vines and fungi, broken bow revealing a dark circular interior, periscope tower and antennae protruding above tall slender trees, shallow water pooled with lily pads and reflective puddles around fallen logs, soft diffused morning light and volumetric mist filtering through branches, cinematic moody atmosphere, photorealistic ultra-detailed textures of wet metal, peeling paint, algae, mossy bark and saturated wet ground, fine raindrops and dripping water, subtle biofilm and barnacle-like growths, high dynamic range, muted greens and desaturated teal color grading, low-angle wide shot with strong leading lines along the hull, 35mm perspective, high resolution, extremely detailed, hyperreal, filmic grain, long depth of field, atmospheric, hauntingly beautiful composition.
