[Image Quality & Photography Style]
Light-Structure Realism. Ultra-photorealistic, authentic RAW photography.
A highly realistic, natural snapshot taken from a very close distance with a smartphone beside an outdoor swimming pool in midsummer.
Vertical 3:4 composition. Shot with an iPhone's standard wide-angle camera, equivalent to a 24–26mm focal length, featuring natural wide-angle perspective.
The relatively deep depth of field characteristic of smartphone photography keeps the subject sharply in focus while preserving natural details in the background swimming pool and trees.
Avoid excessive portrait-mode background blur, cinematic artificial lighting, extreme HDR, and excessive retouching.
[Subject & Facial Features]
A completely fictional, beautiful Japanese adult woman in her early twenties.
She has a small oval-shaped face, a short midface, softly rounded cheeks, a naturally shaped chin, a small well-proportioned nose, and softly full, slightly pink lips.
Her eyes are large, slightly elongated, almond-shaped, and a subdued grayish-brown color.
Natural double eyelids, delicate eyeliner, long eyelashes, and subtle beige-toned eyeshadow.
A small beauty mark just below one eye.
Her lips are slightly parted, with a natural, relaxed facial expression.
Her gaze is slightly languid, cool, confident, and effortlessly composed.
She raises her chin slightly and looks down toward the camera, which is positioned somewhat below her eye level.
[Hairstyle & Accessories]
Bright champagne-blonde to pale honey-blonde hair.
A loosely gathered updo resembling a short bob, with the hair ends casually collected at the back of her head.
Her bangs are thin, wispy, and irregularly separated, with delicate strands naturally falling across her forehead.
Longer loose strands frame both sides of her face, and fine individual hairs are gently lifted by the warm midsummer breeze.
A large black ribbon hair accessory is positioned on the left side of the back of her head.
Part of the ribbon forms a triangular silhouette resembling cat ears.
She wears small gold hoop earrings and delicate, elongated dangling gold accessories.
[Outfit & Fabric Materials]
A black, extremely small triangle halter-neck bikini.
Thin black straps connect behind the neck.
Small gold metal fittings and delicate decorative elements hang from the center of the bikini top.
The bikini fabric is matte black, with subtle reflections appearing only on wet areas.
Realistically reproduce the shape of the bikini cups, fabric tension, and naturally occurring wrinkles.
The bikini features a deep V-shaped neckline, faithfully representing the body's three-dimensional contours and the natural curves created by gravity.
Over the bikini, she casually wears a lightweight, thin, oversized white button-up shirt.
The shirt has slipped significantly off her shoulders, with the sleeves and fabric loosely gathered around both arms.
Her right shoulder is largely exposed, while the shirt's collar and sleeves flow backward toward her back.
Strong sunlight creates bright highlights on the white shirt, contrasted with deep shadows within the overlapping fabric folds.
Accurately reproduce the fine fabric weave, stitching, buttons, and natural wrinkles.
At the lower-right waist area of the frame, a thin side string from the black bikini bottom is visibly tied.
[HIGHEST PRIORITY: Composition Lock — Strict Composition Preservation]
Vertical 3:4 composition.
A very close-range medium close-up prominently framing the subject from the chest area down to part of the waist.
The camera is positioned slightly below the subject's chest level, looking gently upward from a low angle.
The subject is positioned near the center of the frame, slightly toward the left.
She leans her upper body slightly forward while shifting her hips backward.
Her body is angled diagonally relative to the camera, emphasizing the three-dimensional depth of her shoulders and chest.
Her face is positioned near the upper-left portion of the frame, with her head slightly tilted.
Her chin is raised slightly, and her gaze is directed toward the camera.
The shoulder on the right side of the frame is closer to the camera and appears significantly larger in the foreground.
Natural wide-angle perspective is maintained from the shoulder through the upper arm, chest, and waist.
The white shirt occupies a large portion of the right half of the frame, flowing diagonally from the shoulder toward the waist.
At the bottom edge of the image, parts of the torso and white shirt naturally extend beyond the frame.
Preserve the original image's angles, positions, and spatial relationships of the head, neck, shoulders, chest, torso, and waist as faithfully as possible.
[Background — Midsummer Outdoor Swimming Pool]
A luxurious outdoor resort swimming pool beneath a clear midsummer sky.
Most of the background is occupied by a large swimming pool glowing in vibrant turquoise blue under direct sunlight.
Fine ripples spread across the water surface.
Blue tile patterns on the pool floor appear irregularly distorted by the natural refraction of sunlight through the moving water.
A horizontal pool edge extends behind the subject.
In the lower-left corner of the frame, a bright beige pool deck and a long, narrow drainage grate are visible.
The distant background contains white parasols, white pool lounge chairs, dense dark-green hedges, summer trees, and white resort-style architecture.
The upper portion of the frame shows a clear blue sky with a few faint white clouds.
Tropical palm leaves extend into the upper-right corner.
The background must resemble a genuine outdoor poolside environment, without any artificial compositing appearance.
[MOST IMPORTANT: Light-Structure Realism — Intense Direct Midsummer Sunlight]
A nearly cloudless midsummer day, around noon.
Extremely strong natural sunlight shines down from a high solar position.
The sunlight travels diagonally from the upper-left toward the lower-right of the frame.
It creates strong, clearly defined highlights on the hair, forehead, bridge of the nose, cheeks, shoulders, collarbones, chest, and white shirt.
The shoulder closest to the camera receives particularly intense, clearly visible direct sunlight.
Highlights transition naturally across the rounded surface of the skin.
Wispy bangs cast delicate, irregular shadows across the forehead and eye area.
Physically consistent shadows appear beneath the nose, under the chin, along the neck, across the chest, and within the folds of the shirt.
Subtle bluish-white reflected light from the swimming pool naturally reaches the shadowed areas of the body and white shirt.
The lighting direction, shadow angles, color temperature, and exposure must remain completely consistent between the subject and the background.
Do not use artificial fill lighting that unnaturally brightens only the face.
Do not introduce unexplained rim lighting or any lighting that cannot be physically justified by the scene.
[Skin Texture & Surface Realism]
Extremely realistic adult female skin.
The skin surface shows fine pores, natural skin grain, subtle redness, delicate vellus hairs, and slight natural variations in pigmentation.
A thin layer of perspiration caused by the midsummer heat and small poolside water droplets are scattered across her shoulders and décolletage.
The droplets naturally adhere to the curved surfaces of the skin, creating tiny sparkling reflections under the intense sunlight.
Her skin is smooth but not flawless.
Preserve the subtle surface irregularities, micro-shadows, and authentic lifelike textures visible in real smartphone photography.
No porcelain skin, plastic-looking skin, excessive beauty filters, or artificially exaggerated skin gloss.
[Authentic Smartphone Photography Finish]
Authentic handheld smartphone photography.
Natural smartphone exposure control, mild digital sharpening, fine image noise, and realistic dynamic range.
Allow slight highlight clipping on the brightly illuminated white shirt and shoulders due to the intense direct sunlight.
The blue swimming pool should appear vibrant but without excessive saturation enhancement.
The entire image conveys the intense sunlight, summer heat, and natural atmosphere of a genuine midsummer day.
This must not resemble professional studio photography.
Instead, it should look like a realistic, spontaneous photograph casually taken by a friend holding a smartphone beside a sunlit outdoor swimming pool.
