GPT Image 2.0 プロンプト - 冷たい窓明かりの半写実アニメ調セーラー襟ポートレート

{ "subject": { "description": "A youthful, feminine-presenting character close beside a window, body turned sideways and face turned back to look up at the camera. A short black bob, white blouse with a navy sailor collar, and foliage-obscured close framing establish the identity of this semi-realistic, anime-influenced digital portrait.", "mirror_rules": "Not a mirror selfie. The subject looks toward the camera position. Do not add a phone, mirror, or reflection-based reversal; keep the window frame on image right.", "age": "Youthful appearance, but an exact age cannot be determined from the stylized face. Preserve the reference's apparent age without making the character more childlike.", "expression": { "eyes": { "look": "Relatively large, rounded almond-shaped eyes with dark brown-to-hazel irises and cool reflected window highlights. Defined upper lashes, fine separated lower lashes, and loose hair crossing the eye area.", "energy": "Quiet attention, a little alertness, and a thoughtful, interrupted quality.", "direction": "Looking upward toward the elevated camera, establishing direct eye contact." }, "mouth": { "position": "Lips relaxed and faintly parted, without an obvious smile.", "energy": "A restrained, unspoken moment; muted rose-coral lips with a few small glossy highlights." }, "overall": "A brief pause while turning back, rather than exaggerated surprise or a conventional portrait smile." }, "face": { "preserve_original": "Retain the reference's relatively large eyes, small nose, short midface, tapered but rounded chin, and subtle facial asymmetry. Preserve the semi-realistic character proportions without substituting a celebrity likeness or enlarging the eyes further.", "makeup": "Soft, low-contrast natural makeup: fine brown-black lash definition, individually separated lashes, gentle warm-brown eyelid shading, faint peach cheek color, and lightly glossy rose-coral lips. The brows are largely obscured by hair; do not invent dramatic arches or heavy contouring." } }, "hair": { "color": "Black to cool near-black, with steel-blue and silver-gray reflections on illuminated strands. These are highlights, not blue or silver dyed hair.", "style": "A layered bob between jaw and above-shoulder length, with a roughly central but asymmetric part. Voluminous crown, long wispy bangs across the forehead and eyes, and outward-turning side pieces and ends.", "effect": "Directional strands and narrow reflective highlights, with some piecey separation but no dripping-wet appearance. Keep flyaways above the crown, along the right outline, and across the face rather than creating a perfectly groomed helmet shape." }, "body": { "frame": "Only the head, shoulders, and part of the upper body are visible. The visible outline is slender, but clothing, pose, and cropping prevent reliable inference of full-body proportions.", "waist": "Not clearly visible. Do not introduce waist shaping or exposed midriff.", "chest": "Covered by the white blouse and navy sailor collar. Do not introduce cleavage or emphasize chest anatomy.", "legs": "Entirely outside the frame; do not add them.", "skin": { "visible_areas": [ "Face, jaw, and a small amount of neck above the collar", "A small portion of the ear on image left, partly obscured by hair", "A partially visible bare arm between the torso and the right-side window, plus skin near the wrist at lower right; fingers and joint positions are not fully readable", "The shoulder is covered by the sleeve; the waist, hips, legs, back, and buttocks are covered or outside the frame" ], "tone": "Light ivory with a soft peach-beige undertone. The image-left cheek appears warmer, while window-side facial half-tones carry cool blue-gray light; do not mistake the lighting difference for a change in underlying skin tone.", "texture": "Visually smooth and fine, suggesting a soft matte-to-satin surface. Almost no individually resolved pores, consistent with the semi-realistic illustrated finish. Small highlights are localized to the lips and nose, not spread as oily shine over the face.", "lighting_effect": "Most of the face remains in gentle shade. Narrow highlights describe the nose, while warm reflected color meets cooler window illumination across the cheeks. The visible arm is modeled by side light and nearby occlusion." } }, "pose": { "position": "The body is close to the window on image right, torso angled toward it, with the head turned back and slightly raised toward the camera. The nearer shoulder occupies the lower-left portion of the composition.", "base": "The lower body and primary support are cropped out, so the exact seated arrangement is uncertain. One bent arm occupies the narrow space between the torso and window; do not invent a fully visible hand gesture.", "overall": "A gentle counter-rotation between window-facing torso and camera-facing head. Slight head tilt toward the window, sloping shoulders, and a compact, asymmetric posture." }, "clothing": { "top": { "type": "Short-sleeved white sailor-style blouse with a broad navy collar.", "color": "White fabric, deep navy collar panels, and several narrow parallel white stripes along the collar edges.", "details": "Lightweight cotton-like fabric with visible shoulder seams and natural creases. Slightly loose sleeves, bright illuminated fabric, and pale blue-gray fold shadows. The navy collar spreads across the upper back and shoulders and folds toward the front.", "effect": "Preserve the relaxed, lightly wrinkled fit and the strong contrast between the dark collar and bright sleeve. Avoid a pressed, catalog-uniform presentation." }, "bottom": { "type": "Outside the frame.", "color": "Not determinable.", "details": "Maintain the close crop without inventing a skirt, trousers, or visible legs." } }, "accessories": { "jewelry": [ "Small silver-toned hoop-like and bead-like ear ornaments visible on image left, partly hidden by hair; their exact number and design are not certain.", "A reflective silver-white round-bead bracelet near the wrist at lower right; the image does not reliably distinguish metallic beads from a pearl-like material." ] }, "photography": { "camera_style": "A semi-realistic digital illustration or CG-like portrait built around photographic close-portrait optics. For reconstruction, suggest approximately a 50–85mm full-frame-equivalent lens and an f/1.8–f/2.8 depth-of-field impression. These are visual equivalents, not confirmed equipment or exposure metadata.", "angle": "Clearly above eye level, looking downward, revealing a substantial portion of the crown while the subject looks up. Avoid an eye-level frontal portrait or a low-angle view.", "shot_type": "Tight vertical head-and-shoulders to partial-upper-body portrait. Hair approaches the top edge, the face sits slightly right of center, the white sleeve fills the lower left, and the right-side window frame creates a slightly slanted vertical. Foreground leaves interrupt the top, left, and lower-left edges without obscuring the eyes.", "aspect_ratio": "Approximately 3:4 portrait orientation; the supplied reference is about 736:977.", "texture": "Detailed hair strands and cloth folds contrasted with smoother facial shading and subtly drawn contours. A clean finish without heavy film grain, aggressive HDR, or excessive sharpening.", "lighting": "Daylight motivated by the window on image right and slightly above. Cool silver-blue highlights trace the crown and right-side hair edges; the white sleeve and bracelet catch stronger bright patches, while the face stays comparatively shaded. Warm reflection from the wooden surroundings can reproduce the warmer image-left cheek. Preserve uneven illumination instead of adding symmetrical studio beauty fill.", "depth_of_field": "Focus concentrated on the eyes and face. Very close foreground leaves dissolve into broad soft green shapes. Hair and nearby fabric retain detail, while the wood and window frame soften without losing their recognizable structure." }, "background": { "setting": "A narrow window-side space with warm wooden interior surfaces. It can suggest a vintage carriage or a wood-lined interior nook, but the exact location is not identifiable.", "wall_color": "Warm brown and honey-colored wood mixed with deep shadow; dark blue to blue-gray window framing on image right. No complete wall is exposed.", "elements": [ "A close blue window frame and bright glass area on image right", "Warm wooden vertical trim alongside the window", "Darker wooden surfaces and partial horizontal edges behind the subject", "Heavily defocused green foliage close to the lens along the upper, left, and lower-left edges" ], "atmosphere": "Quiet and spatially enclosed, with a brighter exterior and the subject positioned at the boundary between interior shade and window light.", "lighting": "Cool natural window illumination mixed with warmer reflected color from wood. Uneven background brightness, retaining both deep occlusion and a bright window-side strip." }, "the_vibe": { "energy": "Low-key and still, with alert attention carried by the returning gaze.", "mood": "A suspended moment with curiosity and mild pensiveness, not overt sadness.", "aesthetic": "Semi-realistic anime-influenced portraiture combining natural window light, navy-and-white clothing, and soft green foreground foliage.", "authenticity": "Believability comes from asymmetric hair, ordinary fabric creases, partial obstruction, and irregular light. Preserve the digitally illustrated facial treatment rather than presenting the image as an untouched real photograph.", "intimacy": "The tight camera distance and direct gaze create a brief sense of presence without suggestive posing or body emphasis.", "story": "As though the subject had been looking outside, has just turned toward a sound, and may look away again a moment later.", "caption_energy": "Quiet, brief, and slightly unfinished, such as 'The second I turned back.' Do not render the caption inside the image." }, "constraints": { "must_keep": [ "Semi-realistic digital portrait treatment and reference facial proportions", "Layered black bob, eye-crossing wisps, and cool silver-blue strand highlights", "Elevated camera angle paired with an upward returning gaze", "White short-sleeved blouse, navy sailor collar, and narrow white stripes", "Right-side blue window frame, warm wood, and defocused foreground greenery", "Shaded face with brighter hair and sleeve highlights", "Tight vertical framing, slightly right-offset face, and cropped lower body", "Visible small silver-toned ear ornaments and round-bead bracelet" ], "avoid": [ "Changing the scene into a mirror selfie, phone selfie, or frontal ID-style portrait", "Changing the hair length or turning reflected highlights into blue or silver hair", "Inventing unseen anatomy, lower garments, fingers, or support positions", "Adding exposed skin, a low neckline, or exaggerated body curves", "Replacing the restrained glance with a broad smile, exaggerated surprise, or seductive expression", "Even studio lighting, excessive glow, or perfectly symmetrical composition", "Flat cel-shaded anime, an excessively plastic 3D doll, or a generic live-action studio portrait" ] }, "negative_prompt": [ "mirror selfie", "visible phone", "eye-level frontal view", "full-body framing", "long hair", "silver dyed hair", "further enlarged eyes", "heavy stage makeup", "broad grin", "added skin exposure", "extra fingers", "malformed arms", "oily plastic skin", "flat studio lighting", "excessive HDR", "heavy grain", "text", "watermark" ] }
