Большинство AI-апскейлеров либо слишком сглаживают текстуры, либо вообще меняют лицо.
Вот точный промт, который усиливает детали, убирает пикселизацию и сохраняет 100% сходство лица.

Upscale and enhance the attached source image to true 8K UHD (7680×4320) with a 4x upscale factor, delivering a masterpiece-level, ultra-detailed, hyper-realistic result. Preserve the exact same face with 100% facial similarity-no alterations, morphing, or distortion of facial features. Maintain original skin and surface textures while subtly enhancing micro-details and increasing sharpness (1.5) for crisp clarity. Apply low denoising strength (0.25) to retain natural realism.
Enhance with cinematic lighting, sharp focus, intricate texture depth, seamless high-quality gradients, and vibrant yet natural colors with professional color correction and strong gradient refinement. Avoid any plastic, over-smoothed, blurry, waxy skin, flat textures, pixelation, noise, JPEG artifacts, washed-out tones, CGI/cartoon/3D-render look, loss of detail, distorted eyes, or identity changes. Use DPM++ 2M Karras sampler, 50 steps, and CFG scale 7.0 to ensure a photorealistic, raw photography finish that significantly improves clarity and depth while staying faithful to the original image.
