Tek fotoğraftan dört ifadeli portre paftası

Create a professional ultra-realistic 4-expression character reference sheet using the attached image as the immutable identity source. IDENTITY LOCK (ABSOLUTE PRIORITY) Use the attached image as the permanent biometric identity reference. The exact same person must appear in all four portraits with absolute identity consistency. Preserve facial structure, proportions, asymmetry, age, skin tone, skin texture, eye shape, nose shape, lips, hairstyle, hairline, and all natural facial characteristics exactly as shown. Do not beautify, stylize, reinterpret, idealize, or alter the person's identity in any way. HAIR & CLOTHING (HARD LOCK) Hair must remain identical in every portrait, including length, shape, texture, volume, color, flyaways, and natural imperfections. Clothing must remain exactly the same across all four portraits, preserving fit, material, folds, stitching, proportions, accessories, and every visible detail. No redesign, replacement, or simplification. EXPRESSIONS (ONLY VARIABLE) Generate exactly four distinct facial expressions while keeping every other attribute unchanged. Neutral Happy (natural smile) Angry Surprised Only the facial muscles should change. Head shape, pose, hairstyle, clothing, framing, lighting, and camera position must remain identical throughout the sheet. LAYOUT & COMPOSITION Create a professional 2×2 expression sheet with exactly four equally sized white portrait boxes arranged in a perfect grid. Canvas aspect ratio: 4:5 (portrait) Grid: 2 columns × 2 rows Exactly four portrait boxes—no more, no less Every box must be identical in size with perfectly even spacing and alignment. Each portrait must be centered within its box with identical head scale, crop, and positioning. No borders, frames, panel lines, labels, text, UI elements, or graphic overlays. CAMERA & FRAMING Use one fixed professional studio camera setup for every portrait. Lock the focal length, camera height, camera distance, perspective, crop, lens characteristics, exposure, and framing. Every portrait must have identical head size, position, and scale. HEAD POSITION Keep the subject facing directly toward the camera in every portrait. Do not rotate, tilt, lean, or reposition the head. The only change between images should be the facial expression. LIGHTING Use neutral, soft, evenly balanced professional studio lighting. Maintain identical lighting direction, intensity, shadows, and color temperature across all four portraits. No cinematic lighting, dramatic shadows, rim lighting, colored lighting, or environmental lighting. BACKGROUND Each portrait must have a pure white (#FFFFFF) background with no gradients, texture, reflections, haze, banding, light falloff, or environmental elements. The subject must be cleanly isolated against a perfectly uniform white background. OUTPUT STYLE Ultra-realistic medium-format studio photography with razor-sharp focus, highly detailed skin pores, natural skin texture, realistic eyes, accurate fabric textures, neutral color grading, smooth highlight roll-off, subtle natural film grain, and exceptional photorealistic quality.
