Create a wide horizontal color photograph of a quiet classroom in daytime, with a natural realistic photographic look, soft detail, and a calm studious atmosphere. Keep the image fully photographic, not illustrated, not stylized, not cinematic, and not studio-like. Use a frame ratio close to 640:349.

The composition must be a moderate-wide environmental classroom view, not a close portrait. Show one single female student seated slightly right of center, leaving a large visible classroom environment around her. Keep a large bright window mass on the left side of the frame, a dark green chalkboard mass on the right side, and a softly blurred cropped school desk crossing the lower foreground.

The student is the only person in the image. She is seated alone in the middle ground at a school desk, quietly studying and writing. Her head is bowed slightly forward and angled toward the writing surface. Her eyes look downward at the notebook. Her mouth is closed, with a small neutral concentrated expression. She must not look at the camera, smile, or pose.

She has a short black bob haircut ending around the jaw and upper neck, with compact side hair framing both cheeks. Straight separated bangs fall across the forehead in narrow dark strands. Let a subtle warm highlight catch the outer left edge of her hair from the window light.

Her clothing is a white collared long-sleeve shirt under a beige knitted sleeveless V-neck vest. The vest should look soft and natural, with visible knitted fabric character, and the V-neck opening clearly showing the white shirt collar.

Her writing action must be physically clear and believable. One hand holds a slim pale pen and writes on an open notebook in front of her, with the pen tip touching the page near the left-center area of the notebook. Her other hand rests gently across the open notebook, with relaxed fingers touching the pages. The notebook sits centered on the desk directly beneath both hands. Immediately to the right of the notebook, place a thicker open textbook with visible page thickness and a darker outer edge. Add a few loose pale papers overlapping the near edge of the desk and extending toward the lower center of the frame.

The classroom must remain clearly visible and spacious. The left half of the frame is dominated by a bank of tall metal-framed windows with large vertical panes. Through the glass, show pale blue-gray daylight and a softly distant city skyline. Near the inner edge of the window area, include a cream curtain hanging in a soft vertical fold. Along the windowsill, place several potted green plants at different heights, with some leaves extending visibly into the bright window area.

On the right side of the upper background, place a dark green chalkboard reaching toward the right frame edge. Scatter soft white handwritten mathematical notation across the chalkboard in several loose clusters. Between the window zone and the chalkboard zone, include a narrow gray bulletin-board strip or wall area with several small blue-and-white school notices pinned up.

Use repeated warm orange-brown laminated school desks and brown-backed chairs on simple dark metal frames throughout the room. Keep one large foreground desk cropped across much of the bottom of the frame and slightly softer than the subject. Let additional empty desks and chair backs recede in staggered rows through the middle and background, creating a calm, quiet, unoccupied classroom depth.

Lighting must come naturally from the windows on the left. The left side of the image should be brighter and softer, while the chalkboard side on the right should remain slightly darker and cooler. Maintain a clear but gentle bright-left to dark-right luminance gradient across the frame. Use soft daylight with cool sky fill, plus restrained warm highlights on the student’s window-side cheek, hair edge, shirt sleeve, notebook, paper, and wooden desk surfaces.

Keep the color palette natural and balanced: pale blue-gray daylight, muted green plants and chalkboard, beige knit fabric, pale paper, and warm brown wood. Do not over-saturate any element. The student’s face, hands, notebook, and nearby textbook should carry the clearest local detail. The nearest foreground desk and far background classroom structures should be gently softer but still clearly recognizable.

The overall photographic rendering should feel like a softly polished natural digital photograph: smooth tonal rolloff, moderate local contrast, moderate depth separation, ordinary classroom materials, restrained retouching, and believable skin texture. Skin must look soft and natural with gentle tonal variation across cheek, nose, and chin, without plastic smoothing or glossy beauty-retouch effects.

Do not turn the image into a centered close-up portrait, beauty shot, fashion shot, or social-media pose. Do not add classmates, teachers, or any extra human subject. Do not replace the classroom with an office, café, studio set, or minimalist room. Do not remove the tall windows, plants, cream curtain, chalkboard, repeated desks, or the visible lower foreground desk. Do not reverse the light direction. Do not make the background hyper-sharp or the depth of field extremely shallow.

Avoid frontal beauty lighting, colored rim light, orange-teal grading, heavy cinematic contrast, hard oversharpening, aggressive HDR, extreme saturation, plastic skin, heavy airbrushing, floating pen, disconnected hands, closed notebook, closed textbook, displaced book placement, or any pose where the student faces the camera.

Add a very small white four-point sparkle near the lower-right corner as a subtle overlay detail only.  否定词：close-up portrait, centered face, beauty shot, glamour photography, studio lighting, frontal beauty light, direct eye contact, smiling at camera, posed model, fashion editorial, long hair, different hairstyle, different clothing, blazer, cardigan, crowd of students, teacher, multiple people, office, cafe, studio backdrop, blank wall, missing windows, missing chalkboard, missing desks, missing plants, missing curtain, reversed lighting, strong orange teal grade, cinematic color grading, heavy HDR, oversharpened, extreme saturation, plastic skin, excessive smoothing, glossy skin, illustration, anime, painting, 3D render, CGI, hyper shallow depth of field, extreme bokeh, floating pen, hidden hands, closed notebook, closed textbook, misplaced textbook, logo, watermark, large graphic symbol
