Japanese Modern Back Portrait with Shoji Lighting Prompt

Subject:
{argument name="theme" default="Back view with Japanese lighting"}

Main Subject:
A vertical photo-style portrait. In the center of the frame, a single adult woman sits on a chair with her back to the camera. Her upper body down to her thighs is featured prominently, occupying more than half of the screen. A calm moment in the center of a quiet Japanese room, enveloped in low lighting and soft brightness through a shoji screen.

Person/Expression:
A woman with a delicate and elegant atmosphere, her long black hair flowing naturally. Her face is mostly hidden, focusing on the back of her head. Her head is tilted slightly to the right at an angle that beautifully shows the line from her neck to her shoulders and spine. Although her expression is not directly visible, a quiet and lingering presence is conveyed.

Clothing/Pose:
{argument name="clothing" default="A deep wine-red satin slip dress"}. Thin straps and a low-back design that is wide open at the back. The fabric creates natural drapes and glossy wrinkles from the waist to the seat. The woman sits on a chair with her legs folded and lightly spread to the left and right, and her arms drawn gently across her chest. A posture where the line of the back, shoulder blades, and the drop of the waist look natural.

Background/Light:
{argument name="background" default="A calm Japanese-modern interior"}. Tatami floor, dark wood frames, a shoji window on the right, and a hanging scroll on the back wall. In the back left, there is a vase with thin branches and leaves and a small indirect light; on the right, a wooden desk and a small vase with a single red flower. Include a bit of a low bed or the edge of a sleeping platform in the bottom left. The primary light is soft diffused light coming from the shoji on the right, and the fill light is warm indirect lighting from the back left. The overall tone is slightly bright but maintains quiet shadows. The light on the skin gently touches the shoulders, center of the back, and upper waist, with shadows being natural and not too deep.

Composition/Camera:
2:3 vertical orientation. The camera is almost directly facing the person's back, at a height slightly lower than eye level to mid-level. The person is placed in the center, creating a stable composition with the left and right wooden frames and background elements. The focus is on the back to the waist and the drape of the dress. The background is lightly organized but left enough to feel the atmosphere of the Japanese room. Natural compression typical of a medium-telephoto lens, with a depth of field that is not too shallow to keep the person clear while the background is slightly soft.

Texture/Style:
Realistic photographic expression. The skin is smooth but avoids excessive correction to maintain a natural texture. The satin is rendered with elegant luster and deep red gradations. The textures of wood, tatami, shoji paper, and vases are also natural. The overall style is cinematic, high-quality, and tranquil Japanese-modern photography.

Negative:
Unnatural spine or shoulder shapes, extra fingers, missing fingers, fused limbs, unnatural leg angles, poor contact with props, floating sensation, unnatural gravity, overexposure, plastic-like skin, shadows inconsistent with light sources, gibberish text, logos, watermarks.
