Thoughtful Woman Against a Rock in Classic B&W

Create a classic black-and-white portrait of a thoughtful woman leaning against a rugged rock outdoors. She wears a vintage mid-20th-century blouse with a soft collar and a knee-length skirt; her hair is softly waved and pinned in a retro 1940s style. The lighting is Rembrandt: directional light from the side creates a warm highlight on the cheek and deep shadows on the opposite side, with high contrast and subtle film grain. Compose with an 85mm portrait look and shallow depth of field so the subject is sharply in focus against a softly blurred rocky background. The mood is timeless, elegant, and introspective as she gazes off-camera or into the distance, with one hand resting lightly on the rock and an upright, graceful posture. The scene should feel like a classic studio portrait captured in natural outdoor light, preserving textures of the rock and fabric in monochrome.
