Gpt 4K Identitysafe Photo Upscailers

This prompt is optimized specifically for the GPT image generation system using a reference image. It performs 4K photo upscaling while strictly preserving facial identity, structure, age, and expression. Black-and-white images are automatically colorized with natural, realistic tones, while color images retain their original palette. A single editable bracket enables controlled changes such as lighting, age, clothing, or background without breaking photographic realism.
