Serene Monochrome: Elegant Beach Portrait

An elegant black-and-white portrait of a woman relaxing on a pristine beach. She sits gracefully on soft sand with the ocean at her back, wind lifting her hair. She wears a flowing dress or chic swimsuit with a light shawl, creating a timeless silhouette. Monochrome lighting with cinematic contrast, soft diffused sunlight creating gentle shadows on the cheekbones and collarbones; a subtle backlight along the hairline for a delicate rim. High contrast between light skin and dark clothing, with subtle film grain. Shallow depth of field keeps the woman sharp while the sea is softly blurred. Composition uses rule of thirds, the subject angled slightly, gaze directed toward the distance, conveying serenity and style. Shot with an 85mm lens at wide aperture, 1/200s, ISO 100, natural beach ambiance.
