Turn Photos into Retro Illustration Posters

Chinese version: ``` 请将我上传的每一张照片分别制作成一张独立的高级设计海报，不拼接，每张照片单独输出。整体采用3:4竖版构图，上下两个区域高度严格1:1，各占画面50%。 上半部分保留原始照片，保持主体结构、真实质感、自然光影和原有色彩氛围，仅进行轻微高级摄影调色，使画面具有杂志摄影和艺术展览质感。为适配画面比例，可自然扩展天空、地面或环境背景，但不得拉伸、扭曲或改变主体。 下半部分提取照片中最具识别性的主体、轮廓、姿态与叙事关系，重构为轻盈、稚拙、复古的手绘编辑插画。不要机械描摹细节，以概括造型、略微夸张比例、符号化特征和幽默视觉隐喻重新表达，同时确保一眼可以识别原作。整体风格融合现代主义编辑插画、包豪斯构成、儿童绘本与时装速写气质，形体简洁，线条纤细且略留有手绘感，轻松、聪明、俏皮而克制。 配色从上方照片提取，采用高明度、低至中等饱和度的有限色盘，大面积米白或浅色留白，以小面积互补色作为视觉点缀。使用水彩、水粉、彩铅、粉蜡笔与干刷混合质感，保留纸张颗粒、手工边缘、留白、错版套印和不完美笔触。避免平滑矢量、写实光影、3D渲染和塑料质感。 整体构图平衡、轻盈、有呼吸感，可加入少量手绘线条、几何符号或抽象元素。文字可用于少量复古手写标题、编号或年份，使其自然融入插画。 整体气质参考老式时装画报、旅行插画、艺术出版与高级编辑设计，呈现温柔、怀旧、松弛、时髦、幽默、略带笨拙和自信洒脱的感觉，避免卡通感、廉价感、电商感和模板化。 ``` English version: ``` Please turn each photo I upload into a separate, high-end design poster. Do not combine multiple photos into a collage; output one poster per photo. Use an overall 3:4 vertical composition, strictly divided into two equal sections, with the top and bottom each occupying exactly 50% of the canvas height. For the top half, preserve the original photograph, maintaining the subject’s structure, realistic texture, natural lighting, and original color atmosphere. Apply only subtle, refined photographic color grading to achieve the aesthetic of editorial magazine photography and fine-art exhibition imagery. To adapt the image to the required aspect ratio, naturally extend the sky, ground, or environment as needed, but do not stretch, distort, or alter the main subject. For the bottom half, extract the most recognizable subject, silhouette, pose, and narrative relationships from the photograph, then reinterpret them as a light, naorie retro hand-drawn editorial illustration. Do not mechanically trace every detail. Instead, reinterpret the subject through simplified forms, slightly exaggerated proportions, symbolic features, and humorous visual metaphors, while ensuring that the original subject remains instantly recognizable. Blend the aesthetics of modernist editorial illustration, composition, children’s magazines, and fashion sketching. Keep forms concise and lines thin, delicate, and slightly imperfect by hand. The overall feel should be relaxed, intelligent, playful, and restrained. Use a color palette extracted from the photo above, with a vibrant, low-to-medium saturation limited palette. Fill with off-white, airy negative space and a few subtle complementary color accents. Use a mixed-media texture inspired by watercolor, gouache, colored pencils, pastel, and dry brush. Preserve visible paper grain, rough edges, exposed paper, translucent layers, misregistration, and imperfect brushwork. Avoid smooth vector graphics, photorealistic rendering, 3D effects, and plastic-looking finishes. Keep the entire composition balanced, airy, and alive. A small number of hand-drawn lines, geometric symbols, or abstract elements may be added. Use a small number of retro handwritten titles, numbers, or years, integrated naturally into the illustration. The overall style should evoke vintage fashion magazine spreads, travel illustration, art publications, and thoughtful editorial design, feeling gentle, nostalgic, relaxed, witty, playful, slightly naive, and timeless. Avoid anything too cartoonish, cheap, promotional, or template-driven. ```
