AI 小時候合照是什麼？
近期這波「跟小時候的自己合照」的 AI 合成應用來自美圖秀秀的新內建範本，使用者只要上傳兩張照片，就能生成多種有趣的合照風格，例如最夯的 y2k 電梯合照、紅色/白色背景仰拍，以及拍立得風格合照。除了跟偶像或親人合照之外，網友們也發揮創意，將自己的童年照片拿來玩合照，成果十分逼真又有趣！
AI 小時候合照指令：拍立得
指令：Take a Polaroid-style photo with a casual, candid feel. The image should have slight motion blur and even lighting, like a flash in a dark room, softly spread across the scene. Keep the faces unchanged. Replace the background behind the two subjects with a white curtain. The adult and the child should be naturally close, with gentle physical contact, such as leaning together or resting a shoulder against each other.
AI 小時候合照指令：電梯仰拍
指令：Create a composite photo of an adult and a child inside a metallic, brightly-lit elevator with a Y2K vibe. The child stands at the front-left, facing the camera with a natural, cheerful expression. The adult is positioned slightly behind to the right, looking at the child with a warm smile, and naturally resting one hand on the child’s shoulder. Both faces should retain the features of the uploaded photos for realism. The shot must be from a wide-angle, high-angle perspective, as if taken from the top corner of the elevator, making the adult appear taller and emphasizing the unique "elevator high-angle shot" style. The photo should look like a real phone snapshot, with natural skin tones, reflective elevator walls, subtle flash lighting, and detailed light and shadow for an authentic Y2K atmosphere.
AI 小時候合照指令：紅背景自拍
指令：These two photos are of the same girl, one as a child and one as her grown-up self. Please merge the two photos into a single image, where the grown-up version gently places her arm around the child’s shoulder, and they stand together taking a selfie in a red space. The background should be a vivid red wall. The photo should be shot with a wide-angle lens from a low angle, looking upward, as if taken with a real smartphone. Both should be looking directly at the camera, with facial features remaining as close as possible to the original photos. The final image should look highly realistic.

「跟小時候的自己合照」常見問題
最簡單的方法是使用美圖秀秀內建的合照範本，一鍵就能完成。不過若你想要更自由的效果，也可以用 Gemini 或豆包 AI 來合成。只要上傳一張自己的近照，再加上一張小時候的照片，搭配合適的指令，就能生成跟小時候的自己合照。
以紅色背景效果做舉例，指令為："These two photos are of the same girl, one as a child and one as her grown-up self. Please merge the two photos into a single image, where the grown-up version gently places her arm around the child’s shoulder, and they stand together taking a selfie in a red space. The background should be a vivid red wall. The photo should be shot with a wide-angle lens from a low angle, looking upward, as if taken with a real smartphone. Both should be looking directly at the camera, with facial features remaining as close as possible to the original photos. The final image should look highly realistic."（性別自行更改）
在 Gemini 中，選擇 Nano Banana 模型，並上傳兩張照片：一張是現在的你，一張是小時候的你。參考指令如下："Take a Polaroid-style photo with a casual, candid feel. The image should have slight motion blur and even lighting, like a flash in a dark room, softly spread across the scene. Keep the faces unchanged. Replace the background behind the two subjects with a white curtain. Two people should be naturally close, with gentle physical contact, such as leaning together or resting a shoulder against each other."
電梯合照形式多種，以下指令為溫馨且有搭肩的，可再依照需求修改："Create a composite photo of an adult and a child inside a metallic, brightly-lit elevator with a Y2K vibe. The child stands at the front-left, facing the camera with a natural, cheerful expression. The adult is positioned slightly behind to the right, looking at the child with a warm smile, and naturally resting one hand on the child’s shoulder. Both faces should retain the features of the uploaded photos for realism. The shot must be from a wide-angle, high-angle perspective, as if taken from the top corner of the elevator, making the adult appear taller and emphasizing the unique "elevator high-angle shot" style. The photo should look like a real phone snapshot, with natural skin tones, reflective elevator walls, subtle flash lighting, and detailed light and shadow for an authentic Y2K atmosphere.."
