1. 电商主图：陶瓷滤杯

参数：1:1 · 2K · 2048×2048

A clean e-commerce product photograph of a matte ceramic pour-over coffee dripper in soft sage green, centered on a light oak tabletop against a plain warm-white wall. Shot at a slight three-quarter angle from just above the object, 85mm lens, shallow depth of field with the dripper fully in focus. Soft window light from the left creates a gentle gradient on the glaze and a short, soft shadow on the table. Visible fine glaze texture and crisp edges; the shape and proportions are accurate and symmetrical. Minimal styling: one folded linen napkin at the lower right, nothing else. Leave open space above the product for later copy. No text, no logos, no watermark, no extra objects, no distorted shapes.

换成你的产品，改三处就够：产品名和颜色（matte ceramic pour-over coffee dripper in soft sage green）、台面和墙面、右下角那件配角道具。Leave open space above the product 这句保留，主图上方的留白正好放卖点文案。

2. 活动海报：BREW DAY

参数：3:4 · 2K · 1792×2400

A vertical poster for a small neighborhood coffee festival. Warm cream background with a large flat illustration of a coffee cup in terracotta and deep green at the center.

Three text lines only, left-to-right, high contrast, centered, generous margins. Balanced composition with clear space between the headline and the illustration. No other text, no logos, no watermark.

三行英文一次全部拼对，靠的是把每行字放进引号，再写清位置和字重。换成你的活动，只替换三组引号里的文字和中间的插画主体，结尾的 No other text 留着收住多余文字。

3. 时装大片：海岸露台

参数：16:9 · 2K · 2752×1536

A fashion editorial photograph on a sunlit white-stucco terrace above the Mediterranean, shot at eye level with a 50mm lens. One adult woman in her late twenties is walking naturally toward the camera at the right-center of the composition, her head turned slightly toward the sea with a relaxed confident expression. She wears an oversized ivory linen blazer over a deep burgundy silk camisole, high-waisted navy tailored trousers, and simple leather sandals. Wind lifts a few strands of her dark shoulder-length hair and gently moves the blazer hem. A cobalt-blue glazed ceramic bench occupies the left foreground; beyond it, crisp ivory architecture frames a bright turquoise sea and a small distant headland. Directional late-afternoon sunlight reveals real skin texture, linen weave and silk highlights, with clean architectural shadows and controlled reflections. Rich but restrained cobalt, burgundy, ivory and warm skin tones, sophisticated magazine photography, believable proportions and hands, beautifully resolved clothing, candid physical movement, subtle film grain. The woman is the clear visual focus, with the surrounding terrace providing depth. No lettering, no logos, no watermark, no illustration, no CGI appearance, no airbrushed plastic skin.

这条提示词的顺序是：人物和动作 → 每件衣服的颜色与面料 → 两三件场景道具 → 镜头和光线。换模特、换服装时按这个顺序替换对应句子；最后一行排除项保留，用来去掉文字、水印和塑料感皮肤。

4. 模特换装：只换一件外套

参数：参考图 1 张（上一张时装大片） · 2K · 2752×1536

先在模型页上传原图作为参考图（API 里放进 image_input），再运行这条编辑提示词：

Edit this exact fashion photograph. Replace only the woman's oversized ivory linen blazer with a beautifully fitted deep-burgundy soft leather jacket, worn open over the existing silk camisole. Give the jacket realistic fine leather grain, subtle natural highlights and believable folds that follow her current body and walking pose. Preserve the exact woman, face, expression, hair, skin tone, hands, body proportions, pose, navy trousers, sandals, camera framing, cobalt ceramic bench, terrace architecture, sea, sky and every background object. Maintain the existing directional sunlight and shadows; adapt only the jacket's light and reflections to its leather material. This is a garment replacement in the original photograph, not a new scene. Keep the photograph natural and editorial, with no text, no logos and no watermark.

要点是把「改什么」和「保留什么」分成两句：Replace only 后面写新衣服，Preserve the exact 后面逐项列出不能动的东西。套到你自己的图上，用这个句式：

Edit this exact photograph. Replace only the [要改的对象] with [新的样子，写清颜色、面料、版型]. Preserve the exact [人物 / 产品], [脸、发型、姿态、比例], [其他不能动的衣物或物体], camera framing and every background object. Maintain the existing lighting; adapt only the [被改对象] light and reflections to its new material. This is an edit of the original photograph, not a new scene.

5. 家居空间：午后客厅

参数：4:3 · 2K · 2400×1792

An architectural interiors photograph of a carefully curated modern living space, viewed at seated eye level with a 35mm lens. A sculptural walnut lounge chair with a burnt-orange velvet seat stands in the right foreground on warm ivory limestone flooring. Beside it is a low chrome side table holding a clear glass vase with a single white calla lily and an open large-format design book. A softly curved white plaster wall frames the scene; a floor-to-ceiling window at the left reveals a leafy courtyard. Late-afternoon sunlight enters from the left, creating a precise diagonal patch of warm light across the floor and grazing the velvet and curved wood, with gentle room bounce light preserving shadow detail. Clearly visible walnut grain, fine velvet pile, brushed metal reflections, imperfect hand-finished plaster and stone texture. Balanced asymmetrical composition, quiet generosity of space, high-end contemporary interiors magazine photography, natural perspective, warm-neutral palette with one controlled orange accent. No people, no readable lettering, no logos, no watermark, no computer-rendered appearance, no excessive props.

换成你的家具：改主角那把椅子、边桌上的两件配饰和窗外景色。镜头高度和光线方向那两句保留，画面的空间感和质感主要来自它们。

通用写法

按「主体 → 环境 → 镜头 → 光线 → 细节」写，最后一句列出不要的东西。
写具体材质（亚麻织纹、绒面、釉面反光），比"高级""精美"有用得多。
编辑图时，改动项和保留项分开写，保留项逐项列出。
