AI Background Replacement Prompt — Fantasy Landscape

“Keep the person in the foreground exactly as they are — same pose, clothing, lighting on their body, and facial expression. Replace the entire background with a breathtaking fantasy landscape: floating islands with waterfalls cascading into clouds, a massive double moon in a twilight purple-orange sky, bioluminescent plants glowing along the cliff edges. Match the lighting direction on the background to the existing light on the person so the composite looks natural. Cinematic color grading.”

1. The key instruction is 'match the lighting direction' — this makes composites look natural
2. Being specific about what to keep ('same pose, clothing, lighting') prevents unwanted changes
3. GPT Image 2 handles foreground/background separation very well with clear instructions
