Geminiでカップル写真をうまく作るコツ

よくできたカップル写真のプロンプトは、いくつかの具体的な問いに答えています。写っているのは誰か、どこにいるのか、何をしているのか、そしてどんな雰囲気の写真にしたいのか、です。

手持ちの写真を加工する場合は、最初に “Keep both people’s faces, hairstyles, body proportions, and identity recognizable.”(二人の顔、髪型、体のバランスを保ち、本人だとわかるようにする)と書いておきましょう。人物そのものは変えずに、シーンやスタイリングの変更に指示を集中させやすくなります。

手順は次のとおりです。

  1. 二人の顔がはっきり写った写真をアップロードします。
  2. 下のプロンプトからひとつ選び、角括弧の中を書き換えます。
  3. SNSに投稿するなら縦長、壁紙やプリント用なら横長の画像を指定します。
  4. 1回目の結果が惜しいところまで来ていたら、“keep everything the same, but change the background to a rainy street at night.”(ほかはそのままで、背景だけ夜の雨の街に変えて)のような短い追加指示を送ります。

言い回しを練りたいときは、これらの例とあわせて、当サイトのGeminiプロンプトツールや画像編集ガイドも使ってみてください。

よくある失敗と手早い直し方

Geminiが顔を変えすぎてしまうときは、本人らしさを保つ指示をもう一度書き、それ以外の部分はシンプルにしてください。できれば、もっと鮮明な参照写真をアップロードしましょう。

手の形が不自然になるときは、複雑なジェスチャーを求めないようにします。指の位置を細かく書くより、“Holding hands naturally”(自然に手をつなぐ)とだけ書くほうが、たいていは失敗しにくくなります。

作り込みすぎた印象になったら、“natural skin texture, realistic proportions, candid expression, no heavy retouching.”(自然な肌の質感、リアルなプロポーション、自然な表情、過度なレタッチなし)を書き足します。逆にもっと洗練された仕上がりにしたいときは、“professional portrait photography”(プロが撮ったポートレート)と指定し、光の当たり方も書いてください。

よくある質問

カップル写真を加工するGeminiプロンプトには何を書けばいいですか?

場所、動作、光、服装、構図、雰囲気の希望を書きます。写真をアップロードする場合は、二人とも本人だとわかるようにし、自然な体のバランスを保つよう指示を加えてください。

参照写真をアップロードしなくても使えますか?

使えます。本人らしさに関わる部分を、“a young couple with dark curly hair and casual linen outfits.”(黒髪のくせ毛で、カジュアルなリネンの服を着た若いカップル)のようなシンプルな描写に置き換えてください。実在のカップルに似せたいときは、参照画像があったほうが役立ちます。

カップル写真を自然なスナップ風にするには?

ポーズではなく、ちょっとした行動を描写しましょう。歩く、料理する、本を選ぶ、コーヒーを一緒に飲む、おしゃべりする、などです。さらに “natural expression”、“unposed moment”、“documentary photography” といった言葉も加えてください。

背景はいいのに、二人が不自然になるのはなぜですか?

一度にたくさんの変更を頼みすぎているのかもしれません。まずは本人らしさとポーズが狙いどおりのポートレートをきれいに生成し、それから追加の指示で場所、光、服装を変えてください。

まとめ

うまくいくGeminiのカップル写真プロンプトは、シーンをはっきり伝えつつ、自然な表情が出る余地を残しています。アイデアをひとつ選んで二人に合わせて細部を調整し、全部を一度に書き直すのではなく、短い追加指示を重ねて仕上げていきましょう。
