Schulstart-Kampagne für Rucksäcke

Transform the uploaded plain backpack product photo into a polished American back-to-school campaign. Preserve the backpack’s exact navy canvas, tan leather trim, buckles, pockets, zippers, proportions, camera angle and scale. Place it beside a cobalt school locker with a few coordinated notebooks, pencils and a reusable bottle; add crisp late-summer morning window light, energetic blue-and-yellow accents, realistic contact shadows and premium retail detail. Keep the backpack fully visible and unobstructed. Do not add brand marks, readable text, people or alter the product design.
