پرامپت عوض کردن پس‌زمینهٔ عکس

Edit the first reference image. Keep the main subject exactly as it is: same shape, pose, proportions, colours, textures, logo and text, and the same position and size in the frame. Replace everything except the subject (the background, the surface it stands on and any clutter around it) with دیوار گچی کرم با نور ملایم عصر و سایهٔ برگ گیاه; if that scene has no surface of its own, stand the subject on a simple matching surface. If a second reference image is provided, use it as the new background instead, matched in perspective and scale. Relight the subject subtly so its light direction, colour temperature and shadows match the new scene, add a natural contact shadow where it touches a surface, and keep the edges clean with realistic depth of field. Photorealistic, seamless composite. No added text, no extra logos, no watermark.
