この画像生成プロンプトは、サンゴ礁を泳ぐウミガメを自然なドキュメンタリー風に捉えた水中写真を目指しています。リアルなライティングと構図を重視し、過度に彩度が高く不自然な色味を避けています。Juggernaut XLやRealVisXLなどのリアル系モデルに加え、水中シーン用のLoRAを使用すると、コースティクス効果がより一層引き立ちます。

最適な結果を得るには、ウミガメを中心から少し外して配置し、ワイドアングルでサンゴ礁の環境を捉えてください。ヒレの微妙なモーションブラーが動きを感じさせ、作為的でない自然な瞬間のように見えます。後処理でテキストや透かしを追加しないことで、リアリティを保てます。

Prompt Overview

This image generation prompt focuses on a natural, documentary-style underwater shot of a sea turtle in a coral reef. The emphasis is on realistic lighting and composition, avoiding overly saturated or artificial-looking colors. Recommended for use with realistic models like Juggernaut XL or RealVisXL, and a LoRA for underwater scenes can enhance the caustics effect.

For best results, keep the turtle slightly off-center and use a wide-angle perspective to capture the reef environment. The slight motion blur on the flippers adds a sense of movement, making the image feel like a candid moment rather than a staged shot. Avoid adding text or watermarks in post-processing to maintain realism.
