为 [CITY] 创作一张精致的 3:4 竖版高端旅行海报。

Create a refined 3:4 vertical premium travel poster for [CITY]. First identify the city, country, architecture, landscape, climate, cultural character, and visual identity. Select ONE iconic and highly recognizable real-world landmark or subject as the HERO. Establish one believable photographic viewpoint and ensure every environmental element logically belongs to that location. Do not create a collage of unrelated landmarks. COMPOSITION: Divide the poster into two perfectly equal sections: 50% top and 50% bottom. Use a warm beige, ivory, or soft-white background with generous negative space and precise alignment. TOP — HERO PHOTOGRAPH: Create an ultra-realistic, high-end editorial photograph of the chosen landmark from a believable real-world viewpoint. Preserve accurate architecture, proportions, materials, surrounding environment, natural lighting, shadows, atmosphere, and geographic character. The scene should feel like premium architectural photography or a museum-quality travel photograph, with realistic textures and sophisticated cinematic composition. BOTTOM — GRAPHIC INTERPRETATION: Reinterpret the same hero landmark as a sophisticated flat graphic design. Extract its most recognizable silhouette, contours, structural details, proportions, and distinctive architectural elements. Simplify them into elegant geometric shapes, flat color blocks, thin lines, restrained divisions, and generous negative space. The landmark must remain instantly recognizable without becoming a realistic illustration, 3D render, cartoon, or game graphic. COLOR & TYPOGRAPHY: Derive a restrained palette of approximately 4–6 colors from the city's architecture, environment, and hero photograph. Keep the palette sophisticated with slightly muted saturation. Add minimal geometric accents only when they improve the composition. Use limited, elegant typography such as: [CITY] [COUNTRY] ARCHITECTURAL STUDY 2026 Use Swiss/international graphic design, architectural exhibition posters, luxury editorial design, and museum visual identity as the aesthetic reference. Keep typography subtle, with generous letter spacing and strong visual hierarchy. FINAL AESTHETIC: Sophisticated, minimal, contemporary, culturally authentic, artistic, and premium. The photographic upper half and graphic lower half should feel like two expressions of the same visual identity. The final result should resemble a world-class gallery poster, collector's travel print, architectural exhibition artwork, or luxury brand campaign. Avoid landmark collages, inaccurate architecture, invented structures, excessive text, tourist-brochure aesthetics, neon, flashy effects, heavy gradients, glossy 3D rendering, cartoon styling, game UI, clutter, excessive decoration, and generic AI-generated cityscapes.

为 [CITY] 创作一张精致的 3:4 竖版高端旅行海报。 首先识别该城市、所属国家、建筑风格、地形地貌、气候特征、文化特质与视觉识别。选取 ONE 个标志性的、辨识度极高的真实世界地标或主体作为 HERO（核心主角）。确定一个可信的摄影视角，确保每一处环境元素都合理地属于该地点。不要拼贴无关的地标。 构图：将海报划分为两个完全相等的区域：上部 50%，下部 50%。使用暖米色、象牙白或柔白色作为背景，留有充足的负空间，并保持精确的对齐。 上部 —— HERO 摄影：以可信的真实世界视角，创作该地标的超写实高端编辑级照片。保留准确的建筑、比例、材质、周边环境、自然光影、阴影、氛围与地理特征。画面应呈现高端建筑摄影或博物馆级旅行照片的感觉，具有真实的质感与精致的电影级构图。 下部 —— 图形演绎：以精致的扁平图形设计重新诠释同一核心地标。提取其最具辨识度的轮廓、形态、结构细节、比例与独特的建筑元素。将其简化为优雅的几何形状、扁平色块、纤细线条、克制的分割与充足的负空间。地标必须保持一眼可辨，但不要变成写实插画、3D 渲染、卡通或游戏美术。 色彩与字体：从城市的建筑、环境与主照片中提炼一组克制的调色板，约 4–6 种颜色。保持色调精致，饱和度略微降低。仅在能够提升构图时，加入极简的几何点缀。 使用有限而优雅的字体，例如：[CITY] [COUNTRY] ARCHITECTURAL STUDY 2026 以瑞士/国际平面设计、建筑展览海报、奢侈品编辑设计以及博物馆视觉识别作为美学参考。字体保持低调，留有充足的字距，并具备强烈的视觉层级。 最终美学：精致、极简、当代、文化上真实、艺术化且高端。上半部的摄影与下半部的图形应呈现为同一视觉识别的两种表达。最终成品应让人联想到世界级画廊海报、收藏级旅行版画、建筑展览艺术品或奢侈品品牌campaign。 避免：地标拼贴、不准确的建筑、虚构结构、过多文字、宣传册式的旅游审美、霓虹色、浮夸特效、厚重渐变、光泽 3D 渲染、卡通风格、游戏 UI、杂乱堆砌、过度装饰，以及千篇一律的 AI 生成城市景观。
