나노바나나 상품 사진 배경 바꾸기 프롬프트 휴대폰으로 찍은 상품 사진을 연출 컷으로

Edit the attached product photo taken on my phone. Keep the product itself exactly the same: shape, proportions, color, material, label text, logo and every detail must not change. Replace only the background and lighting with [연출 (e.g. a beige stone surface, soft window light, a eucalyptus sprig)]. Add a natural soft shadow under the product that matches the new light, remove dust and any reflection of my hand or phone, and keep the product sharp and centered. Output a [비율 (e.g. 1:1 square)] image suitable for an online store listing.
