Premium burger commercial hero shot with five clean layers

High-end commercial food photography of a premium burger. The burger fills approximately 90% of the frame, centered, fully visible, not a macro close-up. Exactly five clearly readable layers: glossy brioche bun, juicy beef patty, melted cheese, fresh lettuce, ripe tomato. Shot at a clean three-quarter angle to emphasize height, volume, and structure. Backdrop is bright, modern, and advertising-style: smooth vibrant gradient (warm amber to soft orange, or red to golden yellow), evenly lit, with subtle light falloff for depth. No texture, no clutter. Lighting is bold and appetizing: strong soft key light, controlled specular highlights on the bun, visible juice and gloss on the patty and cheese, crisp freshness on vegetables. Shadows are soft and directional, adding dimension without darkening the scene. Ultra-realistic, saturated but natural colors, sharp focus, premium fast-food advertising quality.
