このプロンプトは、熱帯の珊瑚礁の上を泳ぐアオウミガメをドキュメンタリー調の水中写真として生成します。こだわりは水中の自然な光学表現で、水面から差し込む光の筋、甲羅に揺らぐコースティック(光の網目)、水中に漂う微粒子、前肢のわずかなモーションブラーによって「止まった標本」ではなく「生きて動いている」カメに仕上げます。
水中カットはCGっぽいツルツルした質感に転びやすいため、水中ハウジング・35mm相当レンズ・中央を外したフレーミング・自然光といった実機カメラの手がかりを多めに入れています。水の色は「clear turquoise water」で濁りを回避。もっと深い青が欲しいときは「deep cobalt blue water」に差し替え、「distant reef silhouette」を足すと奥行きが出ます。
推奨LoRAは水中写真系または海洋生物ディテール系。甲羅の模様やサンゴの種類が豊かになります。アスペクト比は16:9で広いリーフ景観、4:5でカメ単体のポートレート風が映えます。「8k ultra detailed」などを盛りすぎず、粒子感と軽いブレを残すのがリアルさの鍵です。
Prompt Overview
This prompt produces a documentary-style underwater photograph of a green sea turtle cruising above a tropical coral reef. The emphasis is on natural water optics: sunbeams from the surface, caustic light dancing on the patterned shell, suspended particles and a slight motion blur on the flippers so the animal feels alive rather than frozen.
Because underwater scenes can drift into overly glossy CGI territory, the prompt leans on real-camera cues — underwater housing, 35mm equivalent lens, off-center framing and natural ambient light. Keep the water color keyword "clear turquoise water" to avoid muddy results; if you want deeper blue, swap it for "deep cobalt blue water" and add "distant reef silhouette" for depth.
Optional LoRA: an underwater photography LoRA or a marine-life detail LoRA helps with shell texture and reef coral variety. Generating at 16:9 works well for wide reef vistas; 4:5 crops nicely for a single turtle portrait. Avoid stacking "8k ultra detailed" — the natural grain and mild blur are what sell the realism.
