Generate Himalayan Whiteout Summit Selfies

A hyper-photorealistic selfie portrait taken standing on a narrow exposed rock fin at the summit of a Himalayan peak during a white-out storm, the subject holding the camera toward themselves with a wall of blowing snow and near-zero visibility pressing in from every direction behind them. The light is entirely diffused — a flat, directionless 7500K storm-white ambient coming from all sides simultaneously, the snowstorm acting as a perfect diffusion panel that destroys all shadow geometry on the face. Within this brutal flatness, the only contrast comes from the subject themselves — subsurface scattering renders cold-shocked skin with biological urgency: capillaries fully constricted, the nose bridge and cheekbones showing the first grey-white traces of frostbite beneath the skin surface, lip edges cyanotic. Ice has built up asymmetrically across the face — one eyebrow completely rimed, one partially clear — and each ice crystal is rendered with full spectral refraction. Exhaled breath and moisture from inside the clothing create a dense volumetric fog cloud around the head, immediately shredded by wind and refracting the diffused storm light. Their clothing — whatever they are wearing — is remapped into a high-altitude mountaineering shell: Gore-Tex outer layer with ice-encrusted surface, wind-battered nylon BRDF, oxygen mask hanging loose at the neck. Expression: past fear, past pain — pure survival cognition. Hasselblad X2D 100C, XCD 21mm wide-angle at f/5.6, ISO 3200. Spectral path tracing, full-diffusion storm ambient D7500K. Volumetric blowing snow and breath vapor simulation. ProPhoto RGB, 16-bit linear gamma TIFF, 600 PPI. No stylization, no post-enhancement, no bloom. 2:3 portrait aspect ratio.
