AIが描き出す、写真のようにリアルな猫たちをお届けする「世界ねこ図鑑」シリーズ。
読者の皆様の熱いご要望にお応えして、ついに第9弾の公開です!
今回でなんと累計90品種の猫たちをご紹介することになります。
ついに100品種の到達まで目前に迫りました!!!
これまで8回にわたり、世界中の王道品種から超レアな珍種まで幅広く網羅してきましたが、今回は少し視点を変え、猫好きの間では知られているものの、独立した品種としてはまだマイナー、あるいは特定の団体でのみ認められている「メジャー品種の派生・バリエーション」に焦点を当てました。
例えば、ブリティッシュショートヘアの長毛版「ブリティッシュロングヘア」や、スコティッシュフォールドの立ち耳タイプ「スコティッシュストレート」など、メジャー品種の新しい一面を見せてくれる10品種を選びました。
実生活では「珍しい毛色の〇〇」として扱われることが多い猫たちも、AIならその特定の血統的特徴を正確に捉え、目の前に呼び出すことができます。
質感や解剖学的な正確さにこだわった共通の高品質プロンプトで生成された、成猫と子猫の美しい姿をぜひご覧ください。

成猫・子猫とも、想定していたよりも長毛種の特徴が出ませんでした。
ベンガルのイメージに引っ張られている感があります。

プロンプト(クリックしてご覧ください。文字数が多いので閲覧時はご注意ください)
A photorealistic, extremely high-resolution photograph of an adult, long-haired Cashmere cat. The cat is standing gracefully on a polished, warm-toned hardwood floor, with its entire body and all features fully visible.
Focus heavily on the specific dense, silky, and exceptionally luxurious long coat that defines the Cashmere breed.
The cat must have a very prominent and flowing ruff (mane) of long fur framing its head and neck, and a long, exceptionally bushy tail, covered in long, waving fur.
The Brown Spotted Tabby pattern is intricate and complex, composed of large, irregular rosettes and marbled swirls (not small, distinct dots) across its torso and back, with tabby bars on the legs.
All anatomical features, including precisely positioned ears, eyes with physically accurate irises and clear reflections, nose, and all four paws, are correctly formed without structural distortion.
The natural daylight from a large window creates subtle highlights and shadows, accentuating the coat’s sheen and texture.
A blurred background of rich, antique indoor furnishings (wood furniture, textile) adds depth, without unnecessary decorations.
No chromatic aberration or noise.

プロンプト(クリックしてご覧ください。文字数が多いので閲覧時はご注意ください)
An ultra-high-resolution, macro-detail photograph of a purebred long-haired Brown Spotted Tabby Cashmere kitten, with its entire body and profoundly bushy tail fully visible.
The kitten is in an elegant seated pose on a natural wool rug, looking directly at the camera with a curious, gentle gaze. Its exceedingly dense, plush, and long-piled coat, textured like soft, spun cashmere, features a prominent neck ruff and conspicuous cheek fur that adds volume around its head.
The pattern is a high-contrast Brown Spotted Tabby, with large, defined brown rosettes and intricate spots that remain distinct within the longer fur.
The tail is a standout feature, being exceptionally long, bushy, and plumed.
The head is wide-set with a well-defined muzzle, a pink nose, and wide-set, luminous aqua-green eyes with precise iris patterns and clean light reflections.
The ears are large with prominent internal ear tufts. The paws are large and well-furred, with pink paw pads clearly visible.
Each individual long hair strand is rendered with its own unique direction, texture, and natural sheen, emphasizing the volume and softness without clumpiness.
Diffused, soft daylight from a window illuminates the scene, creating gentle shadows that define the rich textures and bold patterns, avoiding harsh light.
The background is a gently blurred, clean, sunlit interior of an elegant home, providing context without distraction.
The depth of field is very shallow, focusing perfectly on the kitten.
There is no chromatic aberration or noise; the texture is indistinguishable from a real photograph.
