Realistic seaside portrait photography, near 7:10 vertical. An adult East Asian woman with her back to the camera, slender figure, model height, facing the open sea, standing on ground where seaside grass and light brown bare soil interleave. She is positioned slightly left of center; generous sea and sky space is kept above her head; framing from the crown of her head to near the ankles, with shoes naturally cropped. The horizon sits at about one-sixth from the top of the frame, her head around the middle of the frame without disturbing her silhouette; blue-green-toned seawater fills the middle background. Her head and torso face the sea in a pure back view — face and features completely invisible, no head turn. Legs naturally apart, fairly straight with relaxed knees. Leg lines appear slender, thighs naturally tapering toward the knees. Arms close to the torso, right elbow slightly out, hands kept hidden in front of the body.
Deep brown-near-black naturally loose long hair falls to around the waist and back, strands with varied density and layers, some hair blown by the sea breeze toward the left of the frame, sunlit parts warm brown, the hair at the center of the back keeping deeper dark shadow.
Inner layer: a pure white thin-strap camisole top, soft opaque fabric; outer layer: a pure white sheer gauze garment. The outer gauze is light, semi-transparent, naturally draped; the camisole back panel and short skirt silhouette can be partially discerned through the gauze; layered and folded areas look denser white, single-layer edges reveal the colors of the sea and legs through the fabric. Loose cuffs and the two long side hems sway gently toward the left of the frame with the sea breeze, keeping a restrained amplitude. Bottom: a white short pleated skirt, hem at upper thigh, pleats distinct; white vertical-ribbed cotton socks near the ankles. The figure always keeps her back to the camera, never turning around to show the camisole.
Foreground keeps uneven grass, dry hay and light brown soil clumps; on the left a few rough stones, and near the coast at the right rear a low white railing. The sea has continuous fine ripples, broken white foam and local reflections; the distance has a slight atmospheric layering; the sky is light blue, slightly pale-white near the horizon.
Bright natural daylight effect: the left-side hair strands, cloth and legs are brighter, shadows transition to the right, ground shadows extend toward the right of the frame. Preserve the see-through layering of the white gauze and the dark areas of the dark hair; do not blow out the white clothes into textureless pure white blocks. The face-side illumination is consistent with the scene environment, keeping natural light-dark transitions and shadows, no extra fill light or separate face brightening.
The lens shoots at eye level from behind the figure, natural perspective; her hair, gauze folds, skirt hem and leg contours are clear, the waves keep discernible detail, the distance is naturally slightly soft, no heavy background blur. Overall keep the natural color relationship among light blue, blue-green, grass-earth tones and the white clothes.
Output target: 4K resolution at the specified vertical ratio. Quality requirements: prioritize stable figure silhouette and fabric structure; hair strands, gauze layers, knit ribs and water texture clear and natural; visible leg skin keeps fine texture and natural light-shadow transitions appropriate to the framing. Avoid over-smoothing, smeared look, over-sharpening, fake HDR, white edge halos, blocky texture and fabricated detail; do not draw in the hidden face, hands or the cropped shoes; mind the light-and-shadow hierarchy, no unnecessary extra lights.
