当代旅行艺术景观海报

创作一幅精致的当代旅行艺术海报，素材为上传的景观照片。
严格的3:4竖版格式。
上半部分必须保留原始景观照片。保留所有重要的环境结构、自然纹理、光线、阴影、地平线、建筑、人物和透视。不要重新生成场景。
下半部分使用细腻的摄影碎片、网点印刷、细微的纸张纤维和渐隐的边缘，重构景观中最强烈的叙事元素。
使用一个从景观中取样的单一水平几何色块。让重构的主体或地平线与该色块实际相交。
背景大部分保持白色，并保留源自原始图像的柔和色调。避免高饱和色彩。
成品应类似限量版博物馆旅行海报，而非普通的照片拼贴。

Create a sophisticated contemporary travel-art poster from the uploaded londscape photograph.
Strict 3:4 vertical format.
The upper half must remain the original landscape photogroph. Preserve all important environmental structures, natural textures, lighting, shadows, horizon, architecture, people and perspective. Do not regenerate the scene.
The lower half reconstructs the landscape's strongest narrative element using delicate photographic fragments, halftone printing, subtle paper fibers and fading edges.
Use a single horizontal geometric color field sampled from the landscape. Let the reconstructed subject or horizon physically intersect this field.
Keep the background most white with muted tones derived from the original image. Avoid saturated colors.
The result should resemble a limited-edition museum travel poster rather than a conventional photo collage.
