[Overall composition] Generate one standalone 3:4 vertical image divided into upper and lower panels of approximately equal height. The upper panel shows only the uploaded original photograph or original image, and the lower panel shows only a stylistic reinterpretation of the same subject. The entire image contains only one subject: do not add a second subject, introduce unrelated settings, create a side-by-side person-and-pet composition, or add a third panel. Both the original image and the stylized subject occupy the stable visual center of their respective panels. Leave an appropriate safe margin below. [Upper panel | Original image] The uploaded image is the sole basis for the subject's identity, structure, and pose. Preserve its original photographic or imaging texture, natural lighting, setting, colors, and authentic materials. Do not redraw the original or apply artistic filters to it. Prefer embedding the complete original image and filling the layout with blank space. If cropping is necessary, crop only irrelevant background; never crop away key identifying features, change the subject's proportions, or change its pose. Preserve the subject's silhouette, structure, color divisions, material characteristics, accessories, props, gaze, orientation, and pose. No effects from the lower panel may cover the original image above. [Lower panel | Corresponding subject] Reinterpret only the core subject in the original image and its actually present carried props or attached structures, changing the background to pure white. Maintain the same viewpoint, orientation, gaze direction, and corresponding pose. If the original is a detail or half-body composition, prioritize the corresponding framing below as well. If the original shows the full body or complete subject, retain the complete subject below; do not arbitrarily change the pose to fill the frame. Proportions, materials, and structure may change with the style, but the subject's identifying features must remain continuous. Do not replace the subject, change its identity, species, category, apparent age, color divisions, or core structure, or forcibly anthropomorphize a nonhuman subject. [Lower panel | Stencil spray-paint core style] Depict hard-edged black masses created with spray-paint stencils, localized overspray particles, and high contrast. Organize the original image's contours, structural turns, color boundaries, and key identifying features into stencil structures that could actually be cut and sprayed. Use negative shapes to retain the subject's key features, silhouette, and pose. Give hard edges and black masses a rhythm; do not turn every detail into an unrecognizable black blob. Local spray, small missed patches, and rough printing marks serve a handmade feel. Noise appears only on the subject and immediately adjacent areas and must not cover key identifying features. Redraw the subject as a stencil illustration rather than overlaying a red-and-black filter on the real original image. Keep the background pure white with breathing room. Do not add walls, slogans, sticker text, or stains across the entire frame. [Center line and transition] A few red and black spray particles stay below the center line without entering the original image above. The transition serves only to help viewers see the correspondence between upper and lower panels. Do not use a thick black horizontal line, let the subject blend across the dividing line, or fuse the two representations into one subject. [Unified quality and text rules] The upper and lower panels must be immediately recognizable as the same subject. The lower panel must clearly reconstruct the style rather than filter the original image. Lines, color blocks, light and shadow, materials, and handmade details must all serve the same style without mixing in unrelated visual styles. Avoid excessive smoothness, meaningless accumulations of detail, random decoration, extra structures, duplicated subjects, and incorrect proportions. Do not add any text, letters, numbers, slogans, logos, brand names, watermarks, borders, or recognizable interface text anywhere in the image. If the upper original image itself contains text, do not alter that original image. The new original image used for this test should instead be selected at the source to have text-free clothing, unbranded props, and a background without writing. Do not reproduce readable text from the original image in the lower panel.
Prompt (Chinese)
【整体构图】 生成一张独立的3:4竖版上下双拼图片,上下区域高度约1:1。上方仅展示上传的原照片或原始影像,下方仅展示同一个主体的风格转译。整张图片只包含一个主体,不增加第二个主体、不加入无关场景、不制作人物与宠物并列画面,也不增加第三个画面。原图与风格化主体均位于各自区域的稳定视觉中心,下方保留适当安全边距。 【上半部分|原图】 上传图是唯一的主体身份、结构与姿态依据。保留原图原有的摄影或影像质感、自然光线、场景、色彩和真实材质,不重绘原图,不为原图施加艺术滤镜。优先完整嵌入原图,以留白补齐版面;如需裁切,只能裁切无关背景,不能切掉关键识别点、改变主体比例或改变姿态。必须保留主体的轮廓、结构、颜色分区、材质特征、配饰、道具、视线、朝向和姿态。下半部分的任何特效都不得覆盖上方原图。 【下半部分|主体对应】 只转译原图中的核心主体及其实际存在的随身道具或附属结构,背景改为纯白。保持相同视角、朝向、视线方向和对应姿态;原图为局部或半身构图时,下方也优先采用对应范围;原图为全身或完整主体时,下方保留完整主体,不为填满画面而随意改变姿势。允许因风格改变比例、材质和结构,但主体辨识特征必须连续。不得替换主体、改变其身份、物种、类别、年龄感、颜色分区或核心结构,不得将非人主体强行拟人化。 【下半部分|模板喷漆核心风格】 呈现模板喷漆形成的硬边黑块、局部overspray喷雾颗粒与高对比。将原图中的轮廓、结构转折、颜色边界和关键识别点组织为可实际切割与喷涂的模板结构。用负形保留主体的关键特征、轮廓和姿态;硬边与黑块应具有节奏,不把所有细节变成无法辨认的大黑团。局部喷雾、细小漏喷与粗糙印刷痕迹服务于手作感,噪点只出现在主体及其紧邻区域,不得盖住关键识别点。主体应重绘为模板插画,而不是在真实原图上叠加红黑滤镜。背景纯白并保留呼吸感,不增添墙体、标语、贴纸文字或满幅污点。 【中线与过渡】 少量红黑喷雾颗粒停留在中线下方,不侵入上方原图。过渡仅用于辅助观看上下对应关系,不使用粗黑横线,不让主体跨线混合,也不把两种表现熔合成一个主体。 【统一质量与文字规则】 上下必须一眼认出是同一个主体,下方必须是明确的风格重构,而不是原图滤镜。线条、色块、明暗、材质与手作细节统一服务于同一风格,不混入无关画风。避免过度光滑、无意义的细节堆砌、随机装饰、额外结构、重复主体和比例错误。整张图片不得新增文字、字母、数字、标语、Logo、品牌名、水印、边框或可识别的界面文字。若上方原图本身含有文字,不得涂改原图;本次测试使用的新原图应从源头选用无文字服装、无品牌道具和无字背景。下方不得复制原图中的可读文字。
