このプロンプトは、透明度の高い青い海中で珊瑚礁の上を泳ぐアオウミガメのリアルな水中写真を生成します。海洋生物のポスター、環境教育資料、旅行ブログ、水族館やダイビング関連のコンテンツに最適です。ウミガメを主役に据え、水面から差し込む光の筋と小さな熱帯魚が奥行きと状況を添え、被写体から注意をそらさない構図になっています。
スタイルは光沢のあるCG調ではなく、ドキュメンタリー写真のルックを目指します。「自然光」「水中ハウジング」「わずかな動体ブラー」「微細なフィルムグレイン」といったキーワードが、AI生成の水中画像にありがちな滑らかすぎる人工的な印象を抑えます。珊瑚の色をより鮮やかにしたい場合は「鮮やかな珊瑚礁、赤と紫の珊瑚」を、神秘的な雰囲気にしたい場合は「薄暗い青い光、より深い水域」をプロンプトに加えてください。
Stable Diffusionを使う場合、水中や海洋生物のLoRAを併用するとリアリティが向上します。ネガティブプロンプトには「人物、人間、テキスト、ウォーターマーク、歪んだ解剖学的構造」を中心に指定しましょう。FLUXは水中のライティングを得意とするため、まずはこのプロンプトのまま試し、水の透明度や魚の密度を少しずつ調整するのがおすすめです。
Prompt Overview
This prompt generates a photorealistic underwater scene of a green sea turtle swimming above a coral reef in crystal-clear blue water. It is ideal for marine life posters, environmental education materials, travel blogs, and aquarium or diving-related content. The composition emphasizes the turtle as the main subject, with sunlight rays and small fish adding depth and context without distracting from the animal.
The style targets a documentary photograph look rather than a glossy CGI render. Keywords such as 'natural ambient light', 'underwater housing', 'subtle motion blur', and 'slight film grain' help avoid the overly smooth, artificial feel common in AI-generated underwater images. If you want more vibrant coral colors, add 'vivid coral reef, red and purple corals' to the prompt; for a more mysterious mood, try 'dim blue light, deeper water' instead.
For Stable Diffusion users, an underwater or marine life LoRA can enhance realism. Keep the negative prompt focused on 'people, human, text, watermark, distorted anatomy'. FLUX handles underwater lighting well, so start with the prompt as-is and adjust the water clarity or fish density with minor additions.
