Realistic B&W to Colorized Portrait of Dad

"Using the uploaded black and white portrait of dad, naturally colorize the image with realistic skin tones, subtle warmth, detailed hair color (including natural graying if present), and era-appropriate clothing shades. Add balanced lighting while preserving the emotional depth and character of the original photograph. Carefully enhance facial details, eyes, and textures without oversaturation or artificial colors. Maintain a masculine, natural look while keeping the tones authentic to the time period. The final image should look like a naturally captured color photograph from the original era, not digitally altered. Output: photorealistic colorization, cinematic realism, ultra-HD, high resolution, 8K."
