Remove and Replace Photo Background

📸 INPUT REFERENCE: Use the uploaded photo as the base — preserve the main subject exactly as they appear, including precise edge detail around hair strands, fingers, clothing fabric edges and any fine or semi-transparent areas (loose hair, sheer fabric, glasses) ✂️ SUBJECT EXTRACTION: Cleanly separate the main subject from its original background with pixel-accurate edges — no harsh cutout lines, no leftover background color fringing, no loss of fine detail around hair or edges 🌄 BACKGROUND REPLACEMENT: Replace the original background with [DESCRIBE DESIRED BACKGROUND — e.g. "a softly blurred modern office," "a clean seamless studio white backdrop," "a sunlit outdoor park," "a minimalist gradient backdrop"]. Choose lighting, color temperature and depth that realistically complements the subject 💡 LIGHTING MATCH: Adjust the lighting and color grading on the subject so it naturally matches the new background's light direction, color temperature and shadow softness — the subject must look like they were originally photographed in that environment, not pasted on top 🪞 SHADOW & GROUNDING: Add a soft, realistic contact shadow beneath the subject where it naturally meets the new background surface so the subject feels physically grounded in the scene rather than floating 🖌️ STYLE: Photorealistic compositing — final image must look like a single, naturally captured photograph, with zero visible seams, halos or mismatched lighting 🚫 IDENTITY PRESERVATION: Never alter the subject's face, body, pose, or clothing — only the background changes 📐 ASPECT RATIO: Preserve the original photo's aspect ratio unless a new ratio is specifically requested
