  "prompt": "Transform this portrait with professional studio lighting setup, featuring a main key light positioned at 45 degrees to the right of the subject with soft diffusion, a fill light at 45 degrees to the left at half the intensity of the key light to soften shadows, a rim light positioned behind and slightly above the subject to create separation from the background, a subtle hair light from above to add dimension to the hair, all against a neutral gray seamless backdrop. Apply subtle skin retouching while maintaining natural texture, enhance eye clarity and sparkle, balance overall contrast, and add a slight warm tone for a flattering professional headshot appearance.",
