A rugged waxed-canvas backpack product shot, olive-green fabric with brown full-grain leather straps and brass buckles, a leather patch with a stitched brand logo on the front pocket, standing upright on a weathered wooden bench in a vintage outdoor-gear workshop, a tin cup, rolled map, carabiner and small axe hanging from the straps, coils of rope and a lantern on the bench, a wool blanket folded on the bench corner, sawdust and wood shavings on the floor, shelves of tools and old posters blurred behind, warm amber tungsten light. Warm tungsten light from the upper left, cozy workshop evening quality, rich highlights on the waxed canvas, deep soft shadows, subtle grain of the fabric visible, gentle reflection on the brass hardware. Medium close-up shot, three-quarter angle, shallow depth of field, photorealistic canvas, leather and brass detail, 4k
