تصویر تبلیغاتی شمش های طلا در کیسه شفاف

Create a photorealistic luxury product advertisement in a vertical composition. Show several polished rectangular gold bars stacked inside a transparent resealable zip-lock plastic bag. The gold bars should have realistic metallic reflections, sharp beveled edges, subtle engraved markings, and rich warm golden tones. The plastic bag must be clearly visible with natural folds, wrinkles, highlights, and realistic transparency. Place the bag upright on a dark reflective surface against a pure black studio background. Use dramatic high-contrast studio lighting, a soft rim light, controlled specular highlights, realistic shadows, premium commercial product photography, centered composition, front-facing camera, crisp focus, ultra-detailed materials, elegant and luxurious mood, 4:5 aspect ratio. Avoid extra objects, hands, labels, logos, distracting reflections, distorted geometry, melted gold, unrealistic plastic, excessive glare, blur, noise, and illegible large text.
