Prompt
A battered leather boot lies on its side, heel first, on a short conveyor belt that runs in profile across the frame, its leather crazed and its toe scuffed, laces slack along the upper. The belt carries that boot into a small boxy desktop machine standing at the centre of the frame, whose dark entry slot sits at the boot's own height; from the machine's exit the same boot emerges restored, standing upright and polished on the belt, matching the boot that went in in silhouette, lace pattern, leather tone and stitching, with only its condition renewed.
The machine is matte off-white with crisp panel seams, and on the face above its exit sits one circular restart-arrow symbol in relief. No letters or text of any kind appear on the machine or the belt. The camera is level with the belt in a straight side view, so the worn boot, the machine and the restored boot line up along one continuous before-and-after axis, neutral studio light falling evenly from the front-top and a soft contact shadow gathering under each boot where it meets the belt.
The whole apparatus - the conveyor segment, the machine and both boots - is isolated on a fully transparent background - no background at all, alpha = 0, not white, not colored, no checkerboard pattern - carrying only its soft natural contact shadow rendered as semi-transparent black in the alpha channel, darkest where the conveyor frame meets the ground and fading softly outward, delivered with a real alpha channel. The apparatus sits at the centre of a 16:9 wide composition, fully inside the frame with clear margin on every side.
