Mountain Background

Replace the background of this photo with breathtaking [snow-capped mountain peaks under a clear morning sky], so the whole image looks like one real photograph taken on location, not a cutout placed on a backdrop. Keep the person's face, pose, and outfit unchanged, but relight them to match the scene, with crisp cool morning light and a soft ambient glow spilling naturally onto their skin and hair. Blend the peaks behind them with realistic depth, soft atmospheric haze on the distant ranges, and a gently blurred backdrop, add natural contact shadows, and match the color grade and grain across the whole frame. Keep the edges soft and natural around the hair. Photorealistic and seamless, high resolution.
