一张日常照片丢进去，AI在旁边的墙上给你画一个手绘涂鸦版本的“另一个你”。这个涂鸦影子不是普通的物理阴影，而是一个黑色线条手绘的、充满漫画感的“捣蛋鬼”——做着比你夸张一百倍的搞怪动作。
核心反差特别好玩： 涂鸦影子，用各种夸张、混乱、卡通化的方式演绎同一个姿势——比爱心、踮脚、假装偷偷溜走、双手捂脸的可爱逗趣姿势。就好像你的影子有了自己的想法，还在墙上疯狂整活。
小红书上的案例点赞已经几十万了。有人传了一张很正常的全身照，旁边的涂鸦影子在比一个巨大的爱心，表情像是“我玩得超开心”——而真人一脸“我为什么会在这”的尴尬。这种一本正经的人和疯疯癫癫的影子之间的反差感，真的太有梗了。
而且每次生成的姿势都不一样。你可以传不同的照片，AI会给你创作不同的搞怪互动。同一个玩法，每次出来的效果都是独一无二的，特别适合做头像或者发朋友圈。
操作其实特别简单：
准备一张你的全身照或接近全身的照片，背景最好是干净的墙面或浅色背景
打开ChatGPT（GPT-4o）或Google Gemini
上传你的照片

提示词在这，直接复制就能用：
Use the uploaded character reference image as the strict identity and outfit reference. Preserve the reference character’s: face identity, facial proportions, eye shape, nose, lips, skin tone, hairstyle, hair color, visible hair accessories, overall recognizable vibe, outfit and styling shown in the reference image. Do not hardcode any specific character traits that are not present in the uploaded reference. All identity, hairstyle, accessories, and clothing details must be inferred directly from the uploaded reference image.
Create a high-quality mixed-style vertical portrait showing: 1. a realistic full-body version of the uploaded character/person 2. a black hand-drawn doodle-shadow version of the same character/person on the wall beside them.
Core concept: The real person and their doodle-shadow are doing a playful mischievous pose together. The real person performs a cute realistic version of the pose, while the doodle-shadow performs a much more exaggerated, chaotic, cartoonish version of the same pose idea. The mood should feel cute, playful, mischievous, stylish, funny, and social-media-friendly.
Real person: Must remain realistic and photogenic. Must wear the same outfit style and key visible details from the uploaded reference image. Do not replace the reference styling with unrelated fashion. Expression should be cute, slightly confused, mildly embarrassed, playful, as if thinking: “Why am I doing this with my shadow?” The real person should not stand stiffly. The real person should actively participate in the pose, but in a natural realistic way.
Doodle-shadow: Must be a black hand-drawn sketch version of the same person, drawn directly on the wall. Not a realistic second person. Not a normal physical shadow. Not a full-color anime character. Black sketch line-art only. Should resemble the person through hairstyle silhouette, accessories, outfit silhouette, and pose structure. The doodle-shadow should look more energetic, sillier, and more chaotic than the real person. Add manga-like motion lines, hearts, stars, sparkles, and comic marks around the doodle if helpful.
Random mischievous pose rule: The pose must NOT be fixed. For each generation, invent a new playful mischievous pose for both the real person and the doodle-shadow. The real person and the doodle-shadow should share the same general pose idea, but they do not need to match perfectly. The real person performs a cute realistic version. The doodle-shadow performs a much more exaggerated, chaotic, cartoonish version. Do not repeatedly use pointing poses. Do not repeatedly use finger-gun poses. Do not repeatedly use the same standing pose. Do not always make both figures simply point at each other. Create a different mischievous pose each time.
Possible pose directions are loose inspiration only, not a fixed menu: playful idol pose, silly dance pose, leaning sideways with one arm curved overhead, making a big heart pose, cheeky wink pose, hands near cheeks in a cute teasing pose, exaggerated “ta-da!” pose, mock surprise pose, playful running-in-place pose, mischievous tiptoe pose, arms stretched in opposite directions, pretending to sneak away, cute troublemaker pose, dramatic overreaction pose, goofy victory pose, playful balance pose, playful peekaboo pose, shy but mischievous pose, cute overconfident pose.
The final pose should feel fresh, cute, mischievous, and slightly chaotic. The real person should look like they are reluctantly playing along. The doodle-shadow should look like it is having way too much fun.
Composition: vertical 4:5 or 9:16. Show the real person in full-body or nearly full-body framing. Place the real person on one side of the frame. Place the black doodle-shadow on a clean wall beside them. The doodle-shadow should be roughly the same height or slightly taller. Keep enough space around both figures so the full pose is visible. The connection between the real person and the doodle-shadow must be clear at a glance.
Background: simple clean indoor studio wall or minimal room corner. White, cream, or pale gray wall. Clean floor. Soft natural sunlight patch or gentle wall shadow allowed. Keep the background uncluttered.
Lighting: soft natural studio lighting. Bright, clean, polished, playful mood. Keep the real person’s face clearly visible.
Style quality: realistic human photography. Black hand-drawn doodle-shadow on wall. Matching mischievous pose interaction. Strong identity resemblance. Outfit and styling faithfully based on the uploaded reference. Cute and stylish mixed-media portrait. Clean composition. Social-media-friendly. No obvious AI artifacts.
Negative prompt: hardcoded blue hair when not in reference, hardcoded cloud clip when not in reference, hardcoded fish clip when not in reference, hardcoded school uniform when not in reference, outfit change unrelated to reference, realistic second person, normal reflection, normal shadow only, solid black monster shadow, horror shadow, creepy shadow, full-color illustration, cartoon human, anime human, weak resemblance, unrelated sketch character, messy wall, cluttered background, repeated pointing pose, repeated finger-gun pose, same pose every time, fixed pose, boring mirrored pose, stiff pose, identical pose repetition, real person not matching shadow pose, text, watermark, logo, distorted body, extra limbs, extra fingers, bad hands.
Score repair (the only appended change; preserve every source camera/action/composition/foreground/light/scene invariant): Keep the successful real-person/doodle relationship but rotate to a different clearly adult Gallery appearance and a fresh mischievous pose, with this family limited to low frequency rather than appearing in every batch.
几个小技巧：
背景越简单越好，白色或浅灰色墙面效果最佳
尽量选全身照，给AI留够发挥空间
表情可以稍微带点“被迫营业”的无奈感，反差更强烈
一次不满意就多试几次，每次姿势都不一样
适合做什么？ 小红书头像、朋友圈封面、社交账号配图，或者单纯就是好玩。不用露脸也能出片，一张日常照就能变成很有梗的艺术创作。
