85mm F1.4 动漫人像对比

Goal: Create a side-by-side comparison graphic demonstrating an anime portrait prompt improvement using an 85mm F1.4 portrait look. Canvas: Horizontal 16:9 social media image, approximately 1152×768 px. Use a clean split-screen layout with a black-to-dark-gray header band across the top and two equal vertical panels divided by a thin white vertical line. Layout: Top center headline in bold white Japanese text with black drop shadow: 「プロンプト比較:85mm F1.4ポートレート」. Left panel label at the upper left: “Before” in bold white text with dark shadow. Right panel label at the upper right: “After” in the same style. Bottom-left overlay text on the left panel: 「通常生成」. Bottom-center/right overlay text on the right panel: 「85mm F1.4ポートレート」. Use large, high-contrast typography. Subject details: Show the same centered anime-style young male character in both panels, cropped from head to upper torso. He has {argument name="hair color" default="soft silver-white hair with pale lavender and blue highlights"}, fluffy layered tousled hair, delicate androgynous features, a slim neck, and a refined dreamy idol-like presence. Cover the face in each panel with one opaque muted pale-gray square censor block, exactly 2 face-covering squares total, one per panel. The character wears an ornate white shirt and navy sailor-inspired vest with star and moon motifs, a crescent moon brooch, dangling star accessories, a butterfly bow at the chest, ribbons, small gold accents, and delicate jewelry. His hands are held near his chest in a gentle pose. Left panel, Before: Render the background sharply and normally, showing a bright pastel room with a large window, soft daylight, framed pictures, drawers, flower arrangements, plants, and decorative objects. The whole scene is detailed and busy, with the background almost as clear as the character. Right panel, After: Use the same character pose and outfit, but apply a realistic 85mm F1.4 portrait effect: shallow depth of field, creamy background bokeh, soft diffused highlights, blurred flowers and lights, warmer dreamy atmosphere, and stronger subject separation. The background should be heavily defocused while the character remains crisp except for the intentional face-covering square. Visual style: Polished Japanese anime illustration, pastel colors, luminous highlights, elegant fantasy-idol styling, soft airbrushed rendering, high detail on hair and clothing. Add subtle photographic portrait lighting on the After side. Constraints: Include exactly 2 comparison panels, exactly 4 visible text overlays including the headline, exactly 2 face-covering squares, and keep the same character design on both sides. No logos, no watermarks, no extra captions.
