## Prompt

- Model: GPT Image 2

```text
Please turn each photo I upload into a separate premium design poster, no multi-photo stitching, each photo output individually. The layout uses a 3:4 vertical composition, with the top and bottom regions strictly at a 1:1 height ratio, each occupying 50% of the canvas.

The upper part preserves the original photo, keeping the subject's identity, structure, posture, authentic texture, natural lighting, and original color mood, undergoing only subtle premium color grading to match the aesthetic quality of an art magazine and exhibition imagery. To fit the frame, the environmental background can be naturally extended, but the core subject must not be stretched, distorted, or modified.

The lower part extracts only the most recognizable **subject, silhouette, structure, posture, and narrative relationship** from the photo; do not copy the photo completely, do not retain all objects, and do not perform line-by-line tracing. Proactively strip away most irrelevant backgrounds and details, keeping only the core information that best represents the original theme, and apply updated artistic discretion. Even if the original composition is poor, the background is chaotic, or the subject is small, it must be re-directed into a successful standalone piece through omission, reorganization, cropping, scale variations, and white space.

The aesthetic logic of the lower half is reconstructed as a **Stylized Isometric 3D Architectural Diorama / Orthographic Axonometric 3D Render**. It utilizes an **orthographic camera + three-quarter top-down axonometric perspective**, around a 30°–40° tilt down and a 45° horizontal rotation, viewing the front, side, and top simultaneously to project a model, sandbox, miniature world-like spatial dimension. Do not make it a realistic photographic perspective, nor a flat map or blueprint elevation.

Reconstruct the core subject into a **stylized 3D miniature scene**: centering on the subject, retain only a small amount of necessary environmental context such as terrain, roads, bodies of water, platforms, plants, architecture, or objects to form a complete but highly simplified small world. The style is strictly **stylized 3D**, neither low-poly nor realistic CG; emphasizing clean geometry, moderate rounded corners, simplified materials, toy-like proportions, clean blocks, delicate layers, and soft illumination, with fine details possible but never crowded or complex.

The composition maintains a **small-scale subject + a vast amount of intentional white space**. The miniature scene does not have to be centered; it can be arranged freely based on the subject's orientation, proportion, and visual center of gravity, allowing for eccentric, edge-aligned, or partially cropped placement. The white space is not an empty background, but an integral part of the layout, co-creating a sense of breathing room, space, and premium order with the subject. Less is more.

Extract **2-4 of the most vital, memorable colors** from the photo above to re-blend, moderately brightening, purifying, and removing gray tones to create a crisper, cleaner, and more healing color relationship. The overall palette stays vivid but not piercing, warm but not overly sweet, converting naturally into refreshing palettes like sky blue, lake cyan, foliage green, cream yellow; avoid muddy grays, dark dullness, antiquated tones, neon colors, and cheap plastic looks.

Text should feature only minimal editorial intervention with no language restrictions. According to the subject, location, action, mood, or metaphor, freely generate a small amount of headings, short sentences, or annotations to sit quietly in the white space, forming an elegant type-image relationship.

The final output presents a high-end visual result driven by a **stylized axonometric 3D miniature scene, clear spatial definition, fine model-like texture, vibrant colors, massive artistic white space, and editorial layout typography**. Avoid direct cloning of the original image, complicated stacking, realistic perspective, poor low-poly, cheap game vibes, plasticky feel, filled frames, and templated effects.

```text
请将我上传的每一张照片分别制作成一张独立的高级设计海报，不多图拼接，每张照片单独输出。整体采用 3:4 竖版构图，上下两个区域高度严格 1:1，各占画面 50%。

上半部分保留原始照片，保持主体身份、结构、姿态、真实质感、自然光影和原有色彩氛围，仅进行轻微高级调色，使其具有艺术杂志与展览图像质感。为适配画幅，可自然扩展环境背景，但不得拉伸、扭曲或改变主体。

下半部分只提取照片中最具识别性的**主体、轮廓、结构、姿态与叙事关系**，不要完整复制照片，不要保留所有对象，不要逐物转绘；主动删去大部分无关背景与细节，只保留最能代表原始主题的核心信息，并重新做美术判断。哪怕原图构图差、背景乱、主体小，也要通过删减、重组、裁切、尺度变化和留白，把它重新导演成一张成立的作品。

下半部分的美学逻辑重构为 **Stylized Isometric 3D Architectural Diorama / Orthographic Axonometric 3D Render**。采用**正交相机 + 四分之三俯视轴测视角**，大约 30°–40° 俯视、45° 左右水平旋转，同时看到正面、侧面和顶部，呈现模型、沙盘、微缩世界般的空间感。不要做成真实摄影透视，也不要做成纯地图或立面图。

将主体重构为一个**风格化 3D 微缩场景**：以主体为核心，只保留少量必要的环境线索，如地形、道路、水体、平台、植物、建筑或器物，使其组成一个完整但高度概括的小世界。整体是 **stylized 3D**，不是 low-poly，也不是写实 CG；强调规整几何、适度圆角、简化材质、玩具化比例、干净体块、细腻层次与柔和光照，可有精致细节，但不能复杂拥挤。

构图保持**小尺度主体 + 超大量有意识的留白**。微缩场景不必居中，可根据主体方向、比例和视觉重心自由安排，可偏心、贴边或局部裁切。留白不是空背景，而是画面的一部分，要与主体共同形成呼吸感、空间感和高级秩序。宁可少，不要满。

配色从上方照片中提取 **2–4 种最有生命力、最有记忆点的颜色**重新调制，适度提亮、提纯、去灰，形成更明快、干净、治愈的综合色关系。整体保持鲜活但不刺眼，温暖但不甜腻，可自然转化为天空蓝、湖水青、草木绿、奶油黄等清爽色系；避免灰脏、暗沉、陈旧、荧光色和廉价塑料感。

文字只作极少量编辑性介入，不限制语种。可根据主体、地点、动作、情绪或隐喻，自由生成少量标题、短句或注记，安静地落在留白区域，与画面形成精致的图文关系。

整体呈现**风格化轴测 3D 微缩场景、清晰空间关系、精致模型感、鲜活配色、超大量艺术留白与编辑式排版**共同构成的高级视觉效果。避免完整复制原图、复杂堆积、写实透视、低质 low-poly、廉价游戏感、塑料感、画面填满和模板化效果。
