1970年代変身 AI 写真 - レトロ風自分プロンプト

顔・性別はそのままに、髪型・服装・背景を 1970 年代カリフォルニア風に変身。バイラル系自分写真変換。⚠ Gemini は時代変身で性別を入れ替える傾向があるため、プロンプト内で性別ロックを明示。

Restyle the person in the uploaded photo to a classic 1970s-era look while keeping the original biological sex and gender presentation completely unchanged. Add period-appropriate hair styling matching the original gender (e.g., if female: long wavy hair, feathered layers; if male: long curly hair, sideburns or mustache only if originally present), period clothing (e.g., wide-collar shirt, denim jacket, earth-tone turtleneck, or boho dress), and replace the background with an iconic California summer landscape (golden coastal hills, tall palm trees, hazy sunlight). Preserve the person's identity, biological sex, gender presentation, eye shape, nose, jawline, skeletal proportions, and overall facial structure exactly as the source — do not alter the face or change the person's gender. Do not add facial hair (mustache, beard) if it is not present in the source. Output at the original resolution, photorealistic and natural-looking with subtle period film-grain and warm 1970s color grading. Do not regenerate the face from scratch — only operate on the existing pixels and preserve every facial feature exactly. Avoid cartoon, anime, or modern-day elements such as smartphones or contemporary brand logos.

nano-banana」プロンプトとは?

Nano Banana は Google の Gemini 2.5 Flash Image の通称で、ユーザーがアップロードした写真を自然言語の指示で編集できる最新のマルチモーダル画像生成・編集モデルです。Stable Diffusion のようなタグ袋プロンプトではなく、ChatGPT に話しかけるような自然な英語または日本語の祈使文で「この写真の○○を××して」と伝えるだけで、複雑な画像編集タスクをこなします。 Nano Banana が特に得意な領域:(1) 背景透過・置換 — 髪のキワなど境界処理が極めて精密、(2) 被写体の同一性保持 — 顔や体型を保ちつつ服装や髪型だけを変える、(3) 一文完結指示 — マルチターン対話なしで初回指示で結果が出やすい、(4) 写実的な仕上がり — AI 加工特有の「ベタ塗り肌」「人形顔」が出にくい。 最も効果的なプロンプト構造:[1] 対象明示 `the uploaded photo` → [2] 動詞 `Replace / Remove / Change / Restore / Colorize` → [3] 詳細指定 → [4] 保持要素 `keep the face / pose / lighting unchanged` → [5] 出力フォーマット `output as a transparent PNG / 1:1 square / passport size`。例:「Replace the background with a softly blurred professional studio backdrop while keeping the person's pose, lighting direction, and skin tone exactly as in the original. Output as a 1024×1024 PNG.」 本タグでは、Nano Banana / Gemini 2.5 Flash Image 向けに最適化された写真加工指示文を、用途別(背景・人物・修復・着せ替え)に整理して提供しています。
