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。 首先明确这座城市、所在国家、建筑、景观、气候、文化特征与视觉识别。挑选 ONE（一个）标志性的、辨识度极高的真实世界地标或主体作为主角（HERO）。确定一个真实可信的摄影视点，确保每一个环境元素都逻辑性地属于该地点。不要拼贴无关的地标。 构图（COMPOSITION）：将海报分为两个完全相等的部分：顶部 50% 与底部 50%。使用暖米色、象牙色或柔和的白色背景，留出充足的负空间并保持精确的对齐。 顶部 — 主角照片（TOP — HERO PHOTOGRAPH）：从真实可信的视点，创作该地标的一张超写实、高端的编辑级摄影作品。保持准确的建筑、比例、材质、周围环境、自然光、阴影、氛围与地理特征。整体应呈现高端建筑摄影或博物馆级旅行摄影的质感，具有逼真的纹理与精致的电影感构图。 底部 — 图形化诠释（BOTTOM — GRAPHIC INTERPRETATION）：将同一个主角地标重新诠释为精致的扁平化图形设计。提取其最具辨识度的轮廓、轮廓线、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、纤细的线条、克制的分割与充足的负空间。地标必须一眼即可识别，但不得沦为写实插画、3D 渲染、卡通或游戏图形。 色彩与字体（COLOR & TYPOGRAPHY）：从这座城市的建筑、环境与主角照片中提取一个克制、约 4–6 种颜色的色彩方案。保持调性的精致感，使用略低饱和度的颜色。仅在能提升构图时，添加最少的几何点缀。 使用有限而优雅的字体，例如：[CITY] [COUNTRY] ARCHITECTURAL STUDY 2026 以瑞士/国际主义平面设计、建筑展览海报、奢华编辑设计以及博物馆视觉识别作为美学参考。保持字体的克制感，使用大字符间距与强烈的视觉层级。 最终美学（FINAL AESTHETIC）：精致、极简、当代、文化上真实、艺术化且高端。照片的上半部分与图形化的下半部分应呈现为同一视觉识别的两种表达。成品应类似世界级画廊海报、收藏级旅行印刷品、建筑展览艺术品或奢侈品牌广告。 避免：地标拼贴、不准确的建筑、凭空捏造的结构、过度文字、旅行社宣传册式的美学、霓虹色、浮夸效果、过重渐变、过度光泽的 3D 渲染、卡通风格、游戏 UI、杂乱、过度装饰，以及通用 AI 生成的城市景观。
