Use the uploaded image of the leather backpack exactly as it is — do not modify, stylize, or change any part of the product. The shape, texture, color, logo, label, and any text on the backpack must remain 100% untouched and clearly visible, regardless of language. No distortions, replacements, or alterations are allowed.Scene Setup: • Surface: The bottom surface should be fully covered in a fine, light-colored sand layer. The sand must have a natural, realistic texture with soft shadows, unevenness, and subtle granularity. It should feel warm and organic, contrasting gently against the premium leather material. • Pedestal: The backpack must stand upright in a perfectly balanced, natural position on two stacked rectangular stone blocks: • Bottom Block: A porous beige concrete or rough stone block with slightly chipped edges. • Top Block: A flat, dark slate-like stone with a naturally cracked surface and irregular edges, adding rustic character and visual depth. • Shadows: Cast a realistic shadow from the backpack onto the background and surrounding sand. The shadow must be soft and directional, matching the lighting to enhance realism.Background: • A smooth vertical gradient in warm caramel tones, slightly darker at the top and lighter at the bottom. The background tone must dynamically complement the exact leather color of the backpack, reinforcing a luxury aesthetic. • No textures or patterns — the gradient must feel clean, elegant, and studio-lit.Lighting: • Use controlled, soft studio lighting from above and slightly to the side to reveal the rich texture of the leather. Ensure highlights on the curves and natural shadows underneath the product and around the stone base. • Avoid hard reflections or flat lighting. Keep the contrast balanced and elegant.🔍 Focus & Framing: • Full focus on the product — sharp details, premium clarity. • Camera angle: Eye-level or slightly below to make the backpack feel grounded and solid. • Orientation: Vertical 9:18 • Center the backpack in the frame with equal spacing above and below. Must look hyper-realistic, clean, and natural. Do not blur, stylize, or over-light the scene. Do not crop, rotate, or edit any part of the product. No CGI look, no surreal effects.
