Vertical 9:16, extremely bright and clean photorealistic beauty portrait shot in a white interior. A fictional adult Japanese woman, appearing to be {argument name="age" default="23-28 years old"}. Large face placement in the center, a tight close-up from the top of the head to the upper chest. Shoulders tilted slightly to the right, neck slightly to the left, looking directly at the camera. Forehead, eyes, nose, mouth, and jaw all within the frame, with hair flowing long on both sides filling the vertical composition. {argument name="hair style" default="Glossy long hair close to black"}, extending below the chest, parted slightly left of center. Thin, airy see-through bangs on the forehead, a few delicate strands by the cheeks, and loose waves at the ends. Moderate-sized dark brown eyes, natural double eyelids, delicate upper and lower lashes, peach-beige eye makeup, and light coral blush. A natural smile with the mouth slightly open, showing even upper teeth. Glossy pale pink lips. Rounded cheeks and a smooth jawline, healthy bright skin. Preserve details like pores, fine facial hair, lip lines, and iris details. Outfit is a {argument name="clothing" default="white to ivory soft cotton blouse"} with a round neckline, fine gathers at the chest, and small white buttons. No accessories. The background is not pure white, but a very faint gray where the white wall and window light blend. Soft backlight from the subject's back right, with the front of the face evenly filled by a large white reflector. High-key but without blowing out highlights, preserving the black of the hair and the eye contours. Equivalent to 85-105mm, f/2.2, eye-level, priority focus on the pupils. Background blurred smoothly without distorting facial perspective. Balances the precision of a beauty ad with the intimacy of a natural light portrait. No text, logos, watermarks, accessories, flashy nails, extra teeth, mismatched pupils, overly huge eyes, wax-doll skin, heavy contouring, illustrative feel, or 3DCG look.
