Galaxy Background

Galaxy Background

Replace a photo's background with a cosmic galaxy of stars and nebula, blended to match the subject's light.

Replace the background of this photo with a stunning cosmic [deep purple and blue galaxy] of glowing nebula clouds and scattered stars, so the whole image looks like one cohesive photograph, not a cutout placed on a backdrop. Keep the person's face, pose, and outfit unchanged, but relight them to match the scene, with a soft cosmic glow and a gentle colored rim light spilling naturally onto their skin and hair. Blend the galaxy behind them with realistic depth and a soft focus, add subtle starlight reflections, 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.
