Generate Claustrophobic Caver POV Selfies

A claustrophobic, chest-mounted POV selfie of a caver squeezing through a tight limestone 'birth canal' restriction deep underground. The frame is filled with wet, dripping rock walls inches from the face. Their face is smeared with wet clay. The only light comes from their headlamp, which blows out the rock texture directly in front of them and casts deep, scary shadows behind. Technical Specs: Captured with a Phase One IQ4 150MP, 14mm ultra-wide lens (to fit the tight space). ISO 1600 (high ISO grain is acceptable and adds realism). Lighting is single-source harsh LED (5000K). Real geological texture: flowstone, dripping water, and wet mud. Skin texture is pale, cold, and wet. 8K resolution, raw optical realism.
