第 1 步:两张原始人像分别约束脸部身份与身体比例,生成角色母版 v1(原始人像不展示)。第 2 步:只上传 v1,将炭灰长裤调整为米白色,得到页面所示的 v2。以下是两次独立请求,不能合并成一次执行。
STEP 1 — Create the character reference (v1)
Create one square 2-by-2 casting reference sheet. Use Image 1 as the exact primary facial-identity reference. Use Image 2 only as the supporting full-body proportion and hair-length reference; Image 2 must not override the face from Image 1.
Scene:
A clean 2-by-2 grid on a uniform warm-neutral gray studio background (#D8D3CC), with narrow even gutters and no outer decorative border. Soft, broad, neutral daylight comes from camera-left with gentle fill from camera-right. Lighting direction, white balance, exposure, skin tone, background, and wardrobe remain identical in all four panels.
Subject:
The exact same recognizable East Asian woman from Image 1 appears once in each panel. Preserve her real facial identity from Image 1: the same slim oval face, almond-shaped dark eyes, natural eyebrow shape, nose structure, lips, jawline, warm natural skin tone, hairline, age, and individual asymmetries. Use Image 2 to preserve realistic shoulder-to-waist, leg-length, height, and long-hair proportions. Dress her consistently in a lightly structured warm-ivory blazer over an ivory matte blouse, charcoal straight-leg trousers, simple dark flat shoes, and small understated stud earrings. Natural minimal makeup; visible real skin texture.
Important Details:
Top-left panel: head-and-shoulders front view, face perpendicular to camera, direct eye contact only for identity inspection, closed lips, calm neutral expression, hair resting naturally behind one shoulder.
Top-right panel: head-and-shoulders three-quarter view turned approximately 35 degrees toward frame-right, eyes looking slightly beyond camera, closed lips, calm attentive expression.
Bottom-left panel: waist-up clean side profile facing frame-right, both eyes and nose silhouette physically coherent, head level, shoulders relaxed, closed lips.
Bottom-right panel: full-body front three-quarter standing view, feet fully visible on the same neutral floor, arms relaxed naturally at her sides, balanced posture, realistic body proportions and garment drape.
All four panels depict one person during the same studio session. Keep the exact same face, hairstyle, hair length, earrings, wardrobe colors, garment cut, body proportions, and lighting. Leave enough resolution on the three face panels to inspect eyes, nose, lips, jawline, hairline, ears, and natural skin texture. The full-body panel is functional wardrobe and proportion reference, not a fashion pose.
Use Case:
Private production identity reference for deriving consistent photorealistic stills across a workplace short film. This sheet is not a final movie frame and contains no story environment.
Constraints:
One sheet with exactly four panels and exactly one instance of the same woman in each panel. Image 1 has priority for every facial feature; Image 2 contributes only body proportions and hair length. Do not blend, average, beautify, age-shift, ethnicity-shift, slim, reshape, stylize, or reinterpret her face or body. Keep lips closed in all panels. Keep hair length, part, texture, and color consistent. Keep the same blazer, blouse, trousers, shoes, and earrings in every panel. Ignore the pink striped top, jeans, beige sweater, leather skirt, handbag, tall boots, large flower earrings, yacht, lake, trees, and all hand gestures from the references. No labels, captions, names, measurements, height lines, logos, watermark, jewelry changes, glasses, handbag, phone, vehicle, office, outdoor scenery, dramatic colored light, glamour retouching, airbrushed skin, exaggerated smile, duplicate limbs, extra fingers, cropped feet, or additional people.
STEP 2 — Update the trousers (v1 → v2)
Edit the supplied 2-by-2 character reference sheet in place. This is a small wardrobe continuity update to an established character master, not a new character sheet. Change only the existing charcoal trousers in the bottom-right full-body panel to warm ivory suiting fabric. Return one complete square 2-by-2 sheet, with all four existing panels kept in the same positions and proportions.
Change:
In the bottom-right full-body panel, recolor the existing high-waisted straight-leg trousers to a restrained warm off-white that harmonizes with the woman's existing cream blazer and ivory blouse. Preserve the same matte woven suiting texture, original waistband, tailoring, folds, leg width, hem height and ankle exposure. Retain visible creases and softly shaded folds, so the trousers keep their volume and do not become a flat white patch. Use the same neutral studio light already present in the source image. The update should read as a coordinated ivory outfit, not pure overexposed white, glossy satin or yellow fabric.
Preserve:
Keep the top-left front portrait, top-right three-quarter portrait and bottom-left side portrait unchanged in identity, facial features, expression, pose, hairstyle, clothing, lighting and framing. Preserve the bottom-right woman's exact face, age, hair, earrings, body proportions, shoulder width, waist, leg length, hands, standing pose and foot positions. Keep the original cream blazer, ivory blouse and dark flat shoes exactly as they are. Preserve the neutral studio background, floor shadows, camera perspectives, panel sizes, narrow dividers, white balance and overall exposure. Do not re-style, beautify, slim or elongate the character. The original master is the only authority for identity and anatomy.
Constraints:
Only the trouser color changes. Do not add high heels, new shoes, jewelry, makeup, a new nail design, labels, text, logos, measurements, a new pose, an extra person or additional panels. Do not turn any portrait into a full-body image or reveal clothing that was outside its existing crop. Do not replace the sheet with a different casting photo. Do not brighten the whole image or repaint the woman's skin in order to make the trousers lighter. All four panels must remain the same established woman; use the original panel content rather than inventing a new face. No collage comparison or before-and-after arrangement beyond the original four-panel reference layout.
