Prompt Template
{
"prompt": "Restore and fully enhance this old, blurry, faded, and damaged portrait photograph. Transform it into an ultra-high-resolution, photorealistic image with HDR-like lighting, natural depth-of-field, professional digital studio light effects, and realistic bokeh. Apply super-resolution enhancement to recreate lost details in low-resolution or blurred areas. Smooth skin and textures while preserving all micro-details such as individual hair strands, eyelashes, pores, facial features, and fabric threads. Remove noise, scratches, dust, and artifacts completely. Correct colors naturally with accurate contrast and brightness. Maintain realistic shadows, reflections, and lighting dynamics, emphasizing the subject while keeping the background softly blurred. Ensure every element, including clothing and background textures, is ultra-detailed and lifelike. If black-and-white, restore accurate grayscale tones with proper contrast. Avoid over-processing or artificial look. Output should be a professional, modern, ultra-high-quality, photorealistic studio-style portrait, preserving authenticity, proportions, and mood, completely smooth yet ultra-detailed.",
