镜前解开黑色丝带的二十岁女性

▼Theme
Night of untying a black ribbon in front of a mirror

▼Subject
An adult woman in her twenties. Standing in front of an ivory-white wall and a vertically long mirror, with both arms raised above her head. The head is located slightly above the center of the frame, the chest is centered, and the torso to the waist extends diagonally toward the bottom left, with the body slightly leaning back. The body is angled toward the camera, and the mirror on the right side of the frame reflects the back of the head, arms, back, and side of the abdomen. Captured down to below the waist, with legs and toes outside the frame.

▼Person・Expression
Small oval face, short and thin chin, small nose tip. Horizontally long light grayish-brown eyes, glossy pink lips. Long dark brown straight hair, with forehead bangs thinly parted. Bright ivory base color with pale peach skin, cheeks with a thin flush, and light facial shadows. Lips slightly parted, gazing at the camera with a calm and sweet expression. Hair naturally flows to the chest and shoulders, with a portion hanging down along the sides of the cheeks.

▼Clothing・Pose
Black thin satin-style slip dress. Thin shoulder straps, shallow cowl neck at the chest, a large opening from the underarms to the back, with soft diagonal folds on the fabric fitting the torso. The hem of the skirt is outside the frame, no bottom wear added. Wearing small gold openwork dangling earrings. The right arm extends upward on the left side of the frame, the left arm is raised high at the elbow on the right side of the frame, with the forearm crossing over the top of the head. Wide black satin ribbons are wrapped around both wrists, with long ends of the knots hanging down toward both sides of the head. The right hand has fingers slightly bent near the top, the left hand is placed above the top of the head near the right wrist, with fingertips of both hands included in the frame. The lower body maintains a standing posture, legs and toes are not photographed.

▼Background・Lighting
On the left side of the frame is a pale ivory-white wall, with a seam of a vertical wall panel at the left end, a slender vertical decorative strip at the rear left, and a white rectangular switch panel in the center left, with a gray square switch at its center; a vertically long mirror and a thin boundary line are visible on the right side of the frame. The mirror reflects the raised arms, hands, back of the head, back, and the black clothing, with the bright wall in the background highlighting the black clothing. Warm indoor light is cast from the top left of the front, and the reflected light from the mirror on the right and the pale wall softens the shadows of the arms and underarms. There is no strong backlight, preserving a delicate reflective brightness at the silhouette on the mirror side.

▼Composition・Lens
Vertical 3:4. The camera is placed at the height of the person's chest to face, photographed almost horizontally from a position slightly to the left of the front. Included in the frame from the fingertips at the top of the head to below the waist, leaving negative space above the fingertips. A large portion of the person occupies most of the frame, with space for the switch panel on the left and the width of the mirror reflection on the right.

▼Texture・Style
A natural indoor live-action photograph with a main color palette of warm ivory and black. The low-key luster of the satin, the creases of the ribbon, the metal earrings, and the reflection of the mirror are all meticulously depicted and distinguished. Focused on the eyes, preserving natural skin texture. The skin has a smooth gradient tone with small highlights, fine backlight glow at the edges of hair strands, catchlights in the pupils, and the eyes are in focus.

▼Must Comply
Show fingertips above the head and the negative space above them; maintain the configuration of the black clothing with the bright wall and the mirror reflection on the right.
