将输入的城市旅行照片制作成一张竖向3:4上下对比转绘海报，上半约50%保留真实照片中的城市建筑、街道、车辆、行人和地标透视；下半约50%转译为“MONOCHROME TYPE CITY｜黑白巨字城市构成风”。下半用高反差黑白建筑剪影、炭黑暖白、粗半调复印颗粒、碳粉不均和旧纸磨损，提取照片中最准确的城市地标，并用巨大裁切英文标题“CITY / STREET”作为构图骨架，让字母与建筑穿插、出画、遮挡部分笔画。只保留最多一至两种来自照片的专色，不做渐变或全图染色；下半必须改变主体尺度与信息密度并保留连续低信息空场。中线水平清晰，不要普通双色滤镜、照片拼贴、无关地标、Logo、水印、假中文、乱码或原图/AI图角标。
Transform the input city travel photo into a vertical 3:4 split-screen comparison poster. The top ~50% retains the realistic city buildings, streets, vehicles, pedestrians, and perspective from the original photo; the bottom ~50% is reimagined into 'MONOCHROME TYPE CITY' graphic style. The lower half uses high-contrast monochrome architectural silhouettes, charcoal black and warm white, coarse halftone photocopy grain, uneven toner, and distressed paper textures, extracting key landmarks from the photo. Use massive cropped English typography 'CITY / STREET' as the structural framework, letting letters interweave with architecture, clip through frames, and have partial strokes occluded. Retain at most one or two spot colors extracted from the original photo without gradients or full-bleed tinting; the lower half must alter subject scale and information density while maintaining continuous negative space. Keep the horizontal split clean, no generic duotone filters, photo collage, irrelevant landmarks, logos, watermarks, faux Chinese characters, garbled text, or corner badges.

Create a refined vertical art poster that transforms a natural landscape into a flowing topographic world.
Build the terrain from hundreds of long, smooth, continuous contour lines that follow the shape, depth, and movement of the land. The lines should feel like a fusion of topographic maps, silk threads, and abstract Chinese landscape painting — directional, elegant, and highly organized rather than random decorative waves.
Use one strong visual path, such as a river, valley, ridge, cloud road, or negative-space corridor, to guide the eye from foreground to distance.
Keep the natural environment monumental and place only one or two extremely small human figures, boats, or architectural elements as scale anchors.
Use clear spatial hierarchy:
dense flowing lines in the main terrain,
calmer negative space around the visual path,
simpler and softer details in the distance.
Control the palette with 2–4 dominant colors rather than evenly distributed rainbow tones. Use large, clean color fields and let color changes reinforce depth and movement.
Add minimal editorial typography:

[SHORT POETIC LINE]
Typography should feel like a contemporary exhibition poster or art-book cover — elegant, widely spaced, restrained, and secondary to the landscape.
The final image should feel poetic, monumental, calm, and highly designed, combining Eastern landscape aesthetics, contour-line abstraction, negative space, and modern editorial composition.
使用一张真实照片作为唯一内容来源，制作一张竖版上下对比编辑海报。上半部完整保留输入照片的真实摄影质感、主体身份、数量、姿态、空间关系、光线和构图，不把照片画成插画；下半部为同一照片的风格化转绘区：在暖白纸面上，把画面提炼成四个等大的方形像素色块索引，分别对应照片中最有辨识度的主体轮廓、建筑或物体结构、主色与光影关系、一个环境细节。每格使用有限色数的硬边像素块和低分辨率网格感，保留可追溯的形体，不做随机马赛克。四格排列为2×2，周围留出充足纸面；用细黑色十字裁切/定位标记框住索引区域，加入极少量小型双语标题与字段，例如“COLOR INDEX / SCENE STUDY”，文字克制、清晰、像印刷校样标注，不喧宾夺主。下半区必须像一张经过设计的色彩索引卡，而不是滤镜、普通像素化或重复照片；不增加无关物件，不改变照片主题。上下区域约各占一半，水平边界清楚；禁止左右并排、禁止多图拼贴、禁止“原图/AI图”角标、禁止水印和品牌标志。所有颜色从输入照片提取并压缩，四格内容随照片主体变化，适用于人物、动物、建筑、街景、自然、室内、食物和物件等任何照片。
