上記の完全プロンプトとネガティブプロンプトを Replicate / ComfyUI / Forge / Automatic1111 等に貼り付けると、近い結果を再現できます (シードや解像度の違いで完全一致はしません)。

このプロンプトは、AI画像にありがちな過度に鮮やかで完璧な海のシーンを避け、ウミガメのリアルな水中ドキュメンタリー写真を生成することに焦点を当てています。「透き通るターコイズブルーの海」「海面から差し込む太陽の光芒」「自然な被写界深度」といったキーワードが、モデルに望ましい照明と雰囲気を理解させます。

より良い結果を得るには、水中写真やソニーA7R IVなどの特定のカメラモデルで学習されたLoRAを使用すると、画像の信憑性が高まります。「水中に漂う微かな微粒子」と「わずかに不完全なフレーミング」を含めることは、AI生成の水中シーンによく見られるクリーンで無菌的な見た目を打破し、ダイバーが偶然捉えた瞬間のように感じさせるために非常に重要です。
