最近めっきり寒くなってきました。温泉に入ってのんびり温まりたいものです。 そこで、お湯に浸かる画像を生成するにはどんなプロンプトにしたらよいか、実験しました。 まず、Bingチャットで「お湯に浸かるを英語でいうと?」と質問したところ、3つ回答がありました。
温泉の中で、胸までお湯につかるということを英語で訳すと、次のようになります。
To soak in the hot spring water up to your chest.
To immerse yourself in the hot spring water up to your chest.
To submerge yourself in the hot spring water up to your chest.
どれもほぼ同じ意味ですが、ニュアンスとしては、soakはゆっくりと温まる感じ、
immerseは深く浸かる感じ、submergeは完全に水に覆われる感じです。
そこで、生成して比べてみます。モデルはBDさんの _BeyondDream_V01b を使わせていただきました。

考察 上の結果からみると、immerse がお湯に浸かるという点では自然な感じがしました。サンプルがまだ少ないので、今後も試してみます。
