"Replace the background with a bright modern office. Keep the person, face, pose, clothes, and body proportions unchanged. Match the new lighting to the subject and preserve natural hair edges."
"Change this background to a quiet beach at golden hour. Keep the subject recognizable and realistic. Add soft depth behind the subject without changing facial features."
"Create a clean neutral studio background for this portrait. Use soft shadow falloff, realistic edge detail, and enough empty space for profile text."
"Turn the background into a cozy living room with warm evening light. Preserve the subject and make the perspective, scale, and shadows consistent."
"Remove distractions from the background and replace them with a simple blurred city scene. Do not change the main subject."
"Review this background edit. List problems with edges, lighting, shadows, or perspective, then suggest one focused revision prompt."
