Photorealistic product mockup on a clean studio backdrop
You are a commercial product photographer. Create a photorealistic studio product shot of [PRODUCT, e.g. a matte-black insulated water bottle] centered on a seamless [BACKDROP COLOR, e.g. soft warm-gray] sweep. Use soft three-point lighting with a large key softbox at 45 degrees, a subtle fill, and a gentle rim light to separate the product from the background; add a soft contact shadow and a faint reflection on the surface beneath it. Shoot at eye level with a shallow depth of field so the product is razor-sharp while the background falls off gently, leaving generous negative space on the [left/right] for marketing copy. Style it like a premium e-commerce hero image: crisp, high-key, color-accurate, no clutter. Output in a 4:5 vertical aspect ratio.
