Nano Banana Pro 提示词 - 写实双足与自然接触阴影

Edit only the feet in the uploaded image. Generate or complete both feet so they are natural, realistic and visible. If the feet are missing, cropped out or obscured, infer a plausible placement from the legs, body pose and supporting surface. Keep the person's identity, face, pose, clothing, background and composition unchanged. Do not beautify the image or change its style. Ensure correct foot proportions, ankle anatomy and toe count, with no deformities. Match the original skin tone, perspective, lighting, shadows and sharpness, and add natural contact shadows. The result should be photorealistic and blend seamlessly into the original image, with no visible changes outside the foot area.
