🔥 AI 圖片指令第四彈登場！
近期 Google 推出了 Nano Banana，其在生圖生成能力上的提升非常顯著，尤其是在人物與物件的一致性方面。即便在多輪編輯中更改背景、髮型或服飾，主角的原始特徵仍能被保留，大幅度減少出現失真情形。
為了這次 Nano Banana 的發布，我們整理了社群上，如 Threads 和 IG 熱門指令，並調整成更豐富、更具質感的視覺風格設定。從寫實商品感、寫真風格入手，每組 Prompt 指令都經過拆解與優化，讓你可以精準控制材質、光影、構圖與攝影語感。
只要複製下面的指令（Prompt），然後根據需求在結尾加入細節調整（例如背景顏色、角色表情、環境元素等），就能快速生成高質感、符合場景語意的圖片。
