Nano Banana can perform virtually any image editing task you describe: remove unwanted objects or people, replace backgrounds completely, enhance photo details and sharpness, change colors and lighting, modify clothing and outfits, add creative elements or text, fix imperfections, adjust composition, transform time of day or season, swap objects, and much more. The AI understands complex prompts and maintains natural lighting, shadows, and perspective for photorealistic results. If you can describe it, Nano Banana can likely create it.
