逆光中绽放的笑容

Theme:
A smile blooming in backlighting

Subject:
A close-up portrait of a young woman in a white spaghetti strap dress turning her head and smiling in intense sunlight through tree shadows. The character's face and upper body are largely positioned in the center-right of the frame, overlaid with white backlighting on the left, golden translucent hair, and green circular bokeh.

Character · Expression:
A slightly oval melon-seed face with a small rounded chin, face facing directly forward. Large brown almond-shaped eyes, thin and soft arched eyebrows, a thin straight nose bridge and a small nose tip, pale coral glossy lips, a gentle smile showing teeth. Bright skin tone, light pink blush, and understated eye makeup. Chest-length chestnut hair with thin bangs and strands around the face, blown to the right side of the frame by the wind.

Clothing · Pose:
White spaghetti strap dress. The chest has a deep curved neckline, with visible thin patterned weave and a high waistline seam below the chest. The upper body leans forward while twisting towards the left of the frame, with the right shoulder raised forward, only turning the face back to the camera.

Background · Lighting:
The background consists of overall yellow-green leaves and large circular bokeh, with bright sunlight blown out to white on the left side of the frame, and deep green remaining in the upper right. Warm and soft backlighting from the back-left of the frame outlines the hair and shoulders with golden edges, creating lens flare and a light haze.

Composition · Lens:
Vertical 3:4. Level perspective at shoulder height, capturing a close-up from the top of the head to below the chest. The face is largely placed in the upper center, the back of the head and hair are placed at the right end, the chest is cropped at the bottom, and the left half is left as empty space with bright light. Focus on both eyes, with the background heavily blurred.

Texture · Style:
A high-definition realistic photo dominated by white, gold, and yellow-green tones. Realistically depicting natural skin texture, glossy lips, translucent hair strands, thin white fabric, soft backlighting, and circular bokeh.

Negative Prompt:
Significantly changing facial features; do not weaken the intense backlighting on the left
