Minimalist Flat Vector Travel Poster

请将我上传的每张照片转换为一张独立设计的高端海报。不要制作拼贴画或合并多张图像——每张照片应单独处理并输出。采用整体的 **3:4 垂直构图**，画布被严格划分为**上下两个相等的部分**，高度比例为 **1:1**，各占图像的 **50%**。

**上半部分**应保留原始照片，维持主体的身份、结构、姿态、真实质感、自然光线和原始色彩氛围。仅应用微妙、精炼的摄影调色，使其呈现出**艺术杂志、独立出版物或展览摄影**的质感。为契合比例，可以自然延伸天空、地面或环境背景，但主体必须**不得**被拉伸、扭曲或改变。

**下半部分**应从照片中提取最具辨识度的**主体、轮廓、姿态和叙事关系**，并将其重构为**高端极简扁平矢量旅游海报**风格的插画场景。不要机械地描摹照片。相反，应根据原图的视觉个性，提炼出最具代表性的主要视觉焦点，并围绕其构建 **2–4 个辅助元素**，以最恰当地表达环境氛围、日常生活方式、地域感或生活状态。无论原图包含的是城市、建筑、人物、动物、植物、器物、车辆还是自然景观，下半部分都应感觉是为该主体**量身定制的高端旅游视觉海报**，而非应用于所有事物的固定模板。

构图应根据主体自身的特点重新组织，而不是重复相同的布局。运用**明确的焦点、清晰的前后景层次、恰当的留白以及冷静有序的视觉韵律**来构建图像。根据原图，场景可能会自然转变为街道、广场、滨水区、院落、通道、平台、植物环境、室内角落、开阔景观或带有日常生活痕迹的环境片段。主体必须始终是核心视觉中心；所有其他元素应仅用于增强**“这个地方 / 这个物体 / 这种情况”**的独特性。避免拼贴式的地标堆砌、明信片式的罗列或过于叙事性的安排。如果场景中需要人物，仅包含 **3–6 个小比例人物**，自然融入环境，且**没有单一主角**。

整体风格应为**高端极简扁平矢量插画**：灵感源自**日系文具美学、精品贴纸插画和现代社论旅游品牌**。使用**简洁的几何形状、柔和的轮廓、一致的线宽、平涂色块和克制的细节**。整体感觉应该是**清新、安静、精致且现代**的。避免写实主义、厚重的阴影、水彩纹理、纸张纹理、复杂的笔触、渐变、拥挤的背景和过度的细节。

色调应基于**柔和、透气、略显低饱和度的高级色调**，可通过从原图中提取并协调整体色温来调整，同时保持最终结果的轻盈和一致。使用**淡粉蓝、雾霾蓝、天蓝和通透的冷蓝色**构建主要氛围；用**象牙白、奶白色、浅米色、柔和的灰绿色和建筑中性色**来平衡。仅允许使用少量的**灰粉色或暗淡肤色**作为点缀——用于花朵、衣物、小招牌、遮阳篷或局部装饰细节——使画面既透气又显精致且富有层次感。

**文字逻辑**也应成为这种风格的一部分。不要简单地应用城市名称模板。相反，从原图的**地点、物体名称、主题、状况或氛围**中提取一个**简短的标题**，并将其放置在**左上角**或其他留白充裕的区域。配以**简短、克制、有品位的副标题**。排版应保持**低调、社论感、空间感和高端感**，绝不能喧宾夺主。如有必要，添加少量二级文本、坐标式注释或微小的描述性说明，使文字感觉像是来自**高端旅游品牌或精品明信片**的自然视觉识别元素，而不是事后添加的标题栏。

整体效果应感觉像是专为该主体设计的**高端旅游海报 / 精品生活明信片**：**清新、优雅、安静、现代且精致**，拥有充裕的留白和轻松的临场感。**每张海报的下半部分必须有其独立的视觉识别**——绝不能只是更改名称，同时重复使用相同的构图、相同的前景或相同的物体排列。避免任何感觉像是模板化、重复、通用或公式化的标准旅游海报设计。

Please turn each photo I upload into a separate, independently designed high-end poster. Do not make a collage or combine multiple images—each photo should be processed and output individually. Use an overall **3:4 vertical composition**, with the canvas divided into **two equal sections top and bottom**, in a strict **1:1 height ratio**, each occupying **50% of the image**.

The **upper half** should preserve the original photo, maintaining the subject’s identity, structure, pose, authentic texture, natural lighting, and original color atmosphere. Only apply subtle, refined photographic color grading to give it the feel of an **art magazine, independent publication, or exhibition photography**. To fit the format, the sky, ground, or environmental background may be naturally extended if needed, but the main subject must **not** be stretched, distorted, or altered.

The **lower half** should extract the most recognizable **subject, silhouette, pose, and narrative relationship** from the photo, and reconstruct them into a **premium minimalist flat-vector travel poster** style illustrated scene. Do not mechanically trace the photo. Instead, based on the original image’s visual personality, distill the most representative main visual focal point, and build around it with **2–4 supporting elements** that best express the atmosphere of the environment, the way of everyday life, the sense of place, or the state of living. Whether the original image contains a city, architecture, people, animals, plants, objects, vehicles, or natural scenery, the lower half should feel like a **custom-designed high-end travel visual poster** made specifically for that subject, rather than a fixed template applied to everything.

The composition should be reorganized according to the subject’s own character, rather than repeating the same layout. Build the image using **one clear focal point, distinct foreground-background layering, appropriate negative space, and a calm, orderly visual rhythm**. Depending on the original image, the scene may naturally transform into a street, plaza, waterfront, courtyard, passageway, platform, plant-based setting, interior corner, open landscape, or an environmental fragment with traces of daily life. The subject must always remain the primary visual center; all other elements should only reinforce the uniqueness of **“this place / this object / this situation.”** Avoid collage-like landmark stacking, postcard-style listing, or overly narrative arrangements. If people are needed in the scene, include only **3–6 small-scale figures**, naturally integrated into the environment, with **no single protagonist**.

The overall style should be **high-end minimalist flat vector illustration**: inspired by **Japanese stationery aesthetics, boutique sticker illustration, and modern editorial travel branding**. Use **clean geometric forms, soft contours, consistent line weight, flat color blocks, and restrained detailing**. The overall feeling should be **fresh, quiet, delicate, and contemporary**. Avoid realism, heavy shadows, watercolor textures, paper textures, complex brushwork, gradients, crowded backgrounds, and excessive detail.

The color palette should be based on a **soft, airy, slightly desaturated premium palette**, which may be adjusted by extracting and harmonizing the overall color temperature from the original image, while keeping the final result light and cohesive. Use **light pink-blue, misty blue, sky blue, and airy cool blues** to build the main atmosphere; balance them with **ivory white, creamy white, light beige, soft gray-green, and architectural neutrals**. Only allow a small amount of **dusty rose or muted blush** as subtle accents—for flowers, clothing, small signs, awnings, or local decorative details—so the image feels breathable yet still refined and layered.

The **text logic** should also become part of this style. Do not simply apply a city-name template. Instead, extract a **short title** from the original image’s **location, object name, theme, condition, or atmosphere**, and place it in the **upper left corner** or another area with generous negative space. Pair it with a **brief, restrained, tasteful tagline**. Typography should remain **understated, editorial, spacious, and premium**, never overpowering the visual. If necessary, add a small amount of secondary text, coordinate-style annotations, or tiny descriptive notes, so the text feels like a natural visual identity element from a **high-end travel brand or boutique postcard**, rather than a title bar added afterward.

The overall result should feel like a **high-end travel poster / boutique lifestyle postcard** designed specifically for the subject: **fresh, elegant, quiet, modern, and refined**, with generous negative space and a relaxed sense of presence. The **lower half of every poster must have its own independent visual identity**—you must not simply change the name while reusing the same composition, the same foreground, or the same arrangement of objects. Avoid anything that feels templated, repetitive, generic, or formulaic like a standard tourism poster.
