High-Fidelity Sauna Portrait

High-fidelity 8K cinematic portrait. The subject is in an ultra-luxury Finnish sauna, her skin drenched in a heavy, glistening layer of sweat and condensed steam. Physiological details: A deep heat-induced flush across her décolletage and cheeks, chest rising and falling from the humidity. She is wearing a thick white terry-cloth towel, wrapped precariously low and damp to the touch, clinging to her silhouette. Lighting: Low-key amber lighting from beneath cedar benches, creating sharp rim-lights on her wet shoulders and collarbones. High-gloss lips, slightly parted. 35mm f/1.4 lens, intense direct eye contact, volumetric steam swirling around her body.
